Description

Oily liquid cleansing composition

Technical Field

The present invention relates to an oil-based liquid cleansing composition.

Background

Oily liquid cleansing compositions for washing off dirt on the skin and makeup cosmetics are commercially available. The oil-based liquid cleansing composition has a superior cleansing effect compared to emulsion-type cream-like, emulsion-like cleansing compositions or aqueous liquid/gel-like cleansing compositions.

A technique for improving the viscosity of an oily liquid cleansing composition has been developed (japanese patent laid-open nos. 2003-267835 and 2005-2047 of patent document 1) and a technique for improving the solubility of an oily liquid cleansing composition and allowing the composition to be used by wet hands has been developed (japanese patent laid-open No. 3-2005-194249). The present inventors have conducted extensive studies and applied for a patent for the above-described technology (japanese patent application laid-open nos. 2003-252726 and 2005-162691, patent document 4 and 5).

However, since makeup cosmetics having excellent durability such as water resistance and oil resistance have been developed, a cleaning composition having a further excellent cleansing effect has been desired.

Detailed Description

The present invention uses a diester formed from a fatty acid having 6 to 10 carbon atoms and a diol. When a diester with a fatty acid having 11 or more carbon atoms is used, the compatibility with cosmetics is poor, and the feeling is heavy, so that the usability is poor. The fatty acid having 6 to 10 carbon atoms may be 2-ethylhexanoic acid, isononanoic acid, hexanoic acid, octanoic acid, decanoic acid, or the like. Among fatty acids having 6 to 10 carbon atoms, branched fatty acids are more excellent in detergency and in wet-hand usability. The dihydric alcohol can be ethylene glycol, propylene glycol, 1, 3-butanediol, dipropylene glycol, neopentyl glycol, 1, 2-pentanediol, etc. Among the diols, propylene glycol, 1, 3-butanediol and dipropylene glycol are preferable because they can obtain higher detergency.

The diester of a fatty acid having 6 to 10 carbon atoms and a glycol may specifically be ethylene glycol di-2-ethylhexanoate, propylene glycol di-2-ethylhexanoate, 1, 3-butanediol di-2-ethylhexanoate, dipropylene glycol di-2-ethylhexanoate, neopentyl glycol di-2-ethylhexanoate, 1, 2-pentanediol di-2-ethylhexanoate, ethylene glycol di-isononanoate, propylene glycol di-isononanoate, 1, 3-butanediol di-isononanoate, dipropylene glycol di-isononanoate, neopentyl glycol di-isononanoate, 1, 2-pentanediol di-isononanoate, ethylene glycol di-hexanoate, propylene glycol di-hexanoate, 1, 3-butanediol di-hexanoate, dipropylene glycol di-hexanoate, neopentyl glycol di-hexanoate, 1, 2-pentanediol di-octanoate, ethylene glycol di-octanoate, Propylene glycol dicaprylate, 1, 3-butylene glycol dicaprylate, dipropylene glycol dicaprylate, neopentyl glycol dicaprylate, 1, 2-pentanediol dicaprylate, ethylene glycol dicaprate, propylene glycol dicaprate, 1, 3-butylene glycol dicaprate, dipropylene glycol dicaprate, neopentyl glycol dicaprate, 1, 2-pentanediol dicaprate, and the like.

Among the above diesters, ethylene glycol di-2-ethylhexanoate, propylene glycol di-2-ethylhexanoate, 1, 3-butanediol di-2-ethylhexanoate, dipropylene glycol di-2-ethylhexanoate, neopentyl glycol di-2-ethylhexanoate, 1, 2-pentanediol di-2-ethylhexanoate, ethylene glycol di-isononanoate, propylene glycol di-isononanoate, 1, 3-butanediol di-isononanoate, dipropylene glycol di-isononanoate, neopentyl glycol di-isononanoate, and 1, 2-pentanediol di-isononanoate are preferable because they can obtain high detergency. Propylene glycol di-2-ethylhexanoate, 1, 3-butanediol di-2-ethylhexanoate, dipropylene glycol di-2-ethylhexanoate, propylene glycol di-isononanoate, 1, 3-butanediol di-isononanoate, and dipropylene glycol di-isononanoate are particularly preferable because they can provide excellent cleaning ability, rinsing performance, and usability for wet hands.

In addition, it is likewise possible to use particularly preferably propylene glycol di (2-ethylhexanoic acid/isononanoic acid), 1, 3-butanediol di (2-ethylhexanoic acid/isononanoic acid), dipropylene glycol di (2-ethylhexanoic acid/isononanoic acid) as a mixed ester of 2-ethylhexanoic acid and isononanoic acid.

Commercially available diesters of these fatty acids having 6 to 10 carbon atoms and glycols can be used.

Alternatively, the ester can be obtained by combining a fatty acid having 6 to 10 carbon atoms with a diol by a usual method.

For example, an alcohol (1mol) and a fatty acid (2.2mol) are heated to 200 ℃ in the presence of a catalyst, and the water produced is distilled off. After the reaction was sufficiently performed, the excessive fatty acid and the catalyst were removed, and the obtained reaction solution (about 150 to 200 ℃ C., about 0.1Torr) was purified by distillation under reduced pressure to obtain the target ester. The catalyst may be a conventional esterification catalyst (acid catalyst, base catalyst, metal catalyst, etc.).

The oily liquid cleansing composition of the present invention may contain an oil agent other than the diester of the fatty acid having 6 to 10 carbon atoms and the diol, for example, a hydrocarbon oil, a natural oil, an ester oil, a silicone oil, a higher fatty acid, a higher alcohol, and the like.

The hydrocarbon oil may be liquid paraffin, squalane, etc., the natural oil may be olive oil, jojoba oil, etc., the ester oil may be 2-ethylhexyl isononanoate, isononyl isononanoate, isodecyl isononanoate, octyl palmitate, cetyl 2-ethylhexanoate, glyceryl tri (octyl/decanoate), glyceryl tri-2-ethylhexanoate, etc., the silicone oil may be methyl polysiloxane, methylphenyl polysiloxane, etc., the higher fatty acid may be isostearic acid, oleic acid, etc., and the higher alcohol may be octyldodecanol, oleyl alcohol, etc.

The amount of all oils added together with the diester of a fatty acid having 6 to 10 carbon atoms and a diol and other oils used in the present invention is preferably 40 to 95% by mass based on the total composition of the oily liquid cleansing composition of the present invention. If the content is less than 40%, the effect of floating the cosmetic from the skin is insufficient, and the composition is not preferable as an oily liquid cleansing composition. Further, if the content is 95% or more, it is difficult to wash with water.

The amount of the diester of a fatty acid having 6 to 10 carbon atoms and a glycol used in the present invention is preferably 5 to 95% by mass, more preferably 40 to 95% by mass, based on the total composition of the oil-based liquid cleansing composition of the present invention. If the content is less than 5%, the effect of compatibility with cosmetics and the cleansing effect cannot be sufficiently exhibited. When the amount of the surfactant is more than 40% by mass, the compatibility with the cosmetic and the cleansing effect are particularly excellent.

The surfactant used in the present invention is a nonionic surfactant. When only anionic surfactants, cationic surfactants or amphoteric surfactants are used, the compatibility with the oil agent is poor, and the composition is not suitable for use in a cleaning composition. The nonionic surfactant may be used in combination with an anionic surfactant, a cationic surfactant or an amphoteric surfactant, as long as the effects of the present invention are not impaired.

The nonionic surfactant used in the present invention may be a polyglycerol fatty acid ester, a polyoxyethylene glycerol fatty acid ester, a polyoxyethylene sorbitan fatty acid ester, a polyoxyethylene alkyl ether, a hydrogenated castor oil polyoxyethylene ether, a polyoxyethylene sorbitol tetrafatty acid ester, a glycerol fatty acid ester, a sucrose fatty acid ester, an alkyl glucoside, an alkyl polyglucoside, a fatty acid alkanolamide, or the like. The HLB of the nonionic surfactant used in the present invention is preferably 5 to 15, more preferably 6 to 13, from the viewpoint of compatibility with an oil agent and dispersibility in water.

Among the nonionic surfactants, polyglycerol fatty acid esters, polyoxyethylene glycerol fatty acid esters, polyoxyethylene sorbitan fatty acid esters, hydrogenated castor oil polyoxyethylene ethers, and castor oil polyoxyethylene ethers are particularly preferred because they can provide an oily liquid cleansing composition having excellent stability, easy rinsing properties, and excellent performance for use with wet hands.

The polyglycerin fatty acid ester may be decaglyceryl diisostearate, eicosylglycerol hexacaprylate, polyglycerin isostearate, polyglycerin diisostearate, polyglycerin triisostearate, polyglycerin tetraisostearate, polyglycerin laurate, polyglycerin dilaurate, polyglycerin trilaurate, polyglycerin tetralaurate, polyglycerin caprylate, polyglycerin dicaprylate, polyglycerin tricaprylate, polyglycerin tetracaprylate, polyglycerin palmitate, polyglycerin dipalmitate, polyglycerin tripalmitate, polyglycerin tetrapalmitate, or the like.

Examples of the polyoxyethylene glycerin fatty acid esters include polyoxyethylene glycerin triisostearate (20E.O.), polyoxyethylene glycerin mono-coconut oil fatty acid ester (7E.O.), polyoxyethylene glycerin monostearate (5E.O.), and polyoxyethylene glycerin monooleate (15 E.O.).

The polyoxyethylene fatty acid ester may be polyethylene glycol monoisostearate or the like.

The polyoxyethylene sorbitan fatty acid esters include polyoxyethylene sorbitan coconut oil fatty acid ester (20E.O.), polyoxyethylene sorbitan monostearate (20E.O.), polyoxyethylene sorbitan monooleate (20 E.O), and the like.

The sorbitan fatty acid ester may be sorbitan monoisostearate, sorbitan monostearate or the like.

The polyoxyethylene alkyl ether may be polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, polyoxyethylene isostearyl ether, or the like.

The amount of the nonionic surfactant used in the present invention is preferably in the range of 1to 40%, particularly preferably in the range of 5 to 25%, based on the total composition of the oil-based liquid cleansing composition of the present invention. If the content is less than 1%, the detergency and washing performance of the composition are insufficient, and if the content is more than 40%, there is a possibility that "the composition is poor in fluidity and cannot retain an oily liquid state" or "there is a problem such as irritation to the skin during use" may occur.

The oil-based liquid cleansing composition of the present invention may contain water. However, if water is incorporated in a large amount, the oil phase cannot be completely covered with water, and an oil-in-water type emulsified composition is formed. Therefore, the amount of water is preferably less than 50% by mass, and particularly preferably less than 20% by mass.

Functional components such as polyols, polyalkylene glycols, saccharides, lower alcohols, high-molecular substances, organic and inorganic powders, preservatives, antioxidants and the like may be added to the oil-based liquid cleansing composition of the present invention within a range not to impair the functions of the present invention.

Examples

The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples.

The oily liquid cleansing compositions having the compositions shown in tables 1to 4 were prepared according to the following methods, and the transparency, low-temperature stability, high-temperature stability, cosmetic compatibility, washability, and hand-wetting properties of these oily liquid cleansing compositions were evaluated according to the following procedures. The results are shown in tables 1to 4.

(preparation method)

Heating the oil agent and the surfactant to 80 ℃, mixing, and cooling to normal temperature.

(transparency)

The appearance of the oil-based liquid cleansing composition was observed and evaluated according to the following criteria.

O: is transparent

And (delta): semi-transparent

X: not dissolving

(Low temperature stability 5 ℃ C.)

The oily liquid cleansing composition was stored in a thermostatic bath at 5 ℃ for 24 hours and evaluated according to the following criteria.

O: is transparent

And (delta): semi-transparent

X: cloudiness or separation

(high temperature stability 40 ℃ C.)

The oily liquid cleansing composition was stored in a thermostatic bath at 40 ℃ for 24 hours and evaluated according to the following criteria.

O: is transparent

And (delta): semi-transparent

X: cloudiness or separation

(compatibility of cosmetics)

The compatibility with the cosmetic was evaluated by the following method. About 0.1g of liquid foundation was uniformly applied to a circular artificial skin plate (white) (Beaulax, Japanese original name: ビユ - ラツクス) having a diameter of 5cm, which was manufactured by Beaulax, a hair dryer, and a facial tissue was pressed with a hand, so that the skin could not be rubbed and the liquid foundation did not adhere even when the skin tissue was peeled off. Then, 5g of the oily liquid cleansing composition was put into a shallow pan having an inner diameter of 8.5cm, and the liquid foundation application part of the artificial skin plate was faced downward to be in contact with the liquid surface and floated on the oily liquid cleansing composition in the shallow pan. The tray was tilted up and down and left and right, the floating artificial skin plate was reciprocated up and down for 2.5 times and left and right for 2.5 times, and then taken out of the tray, the face tissues were pressed by hand and could not be rubbed, and then removed, and this operation was performed ten times to evaluate the dropping state of the liquid foundation by color difference measurement. The L of an artificial skin plate prepared by applying a liquid foundation before, after, and after dissolving in an oil-based liquid cleansing composition and removing by pressing a facial tissue with a hand, was measured using a spectral variable goniochromatometer model GC5000 manufactured by Nippon Denshoku industries Ltd^*a^*b^*The value is obtained.

Set L of Artificial skin plate before application of liquid Foundation^*a^*b^*A value of L^*(A)、a^*(A)、b^*(A) L of Artificial skin plate after application of liquid Foundation^*a^*b^*A value of L^*(B)、a^*(B)、b^*(B) L of an artificial skin plate which is compatible with an oily liquid cleansing composition and removed by pressing a facial tissue^*a^*b^*A value of L^*(C)、a^*(C)、b^*(C)。

The color difference Δ E (0) between after application and before application of the liquid foundation was obtained by equation 1.

Formula 1

ΔE(0)＝[(L^*(B)-L^*(A))²+(a^*(B)-a^*(A))²+(b^*(B)-b^*(A))²]^1/2

The color difference Δ E (1) between the artificial skin sheet after applying the liquid foundation and dissolving the liquid foundation in the oil-based liquid cleansing composition and after removing the sheet by pressing the tissue paper and the artificial skin sheet before applying the liquid foundation was determined by equation 2.

Formula 2

ΔE(1)＝[(L^*(C)-L^*(A))²+(a^*(C)-a^*(A))²+(b^*(C)-b^*(A))²]^1/2

The residual ratio of the liquid foundation was determined by equation 3.

Formula 3

Residual rate of liquid foundation ═ Δ E (1)/Δ E (0) × 100

The evaluation criteria are as follows.

O: the residual rate of the liquid foundation is less than 50%

And (delta): the residual rate of the liquid foundation is 50% or more and less than 80%

X: the residual rate of the liquid foundation is more than 80%

Or the oil agent and the surfactant are not compatible or uniform, and thus the measurement cannot be performed.

(easy washability)

To a 100mL beaker, 90g of water was added, and 0.1mL of an oily liquid cleansing composition was added, followed by 10-time stirring with a spatula. Since the easily washable oil-based liquid cleansing composition was uniformly dispersed, the following criteria were used for evaluation.

O: and (4) uniformly dispersing.

And (delta): the trace oil floats.

X: oil floats, or non-dispersed suspended matter exists in water.

Or the oil agent and the surfactant are not compatible or uniform, and thus the measurement cannot be performed.

(Wet-hand usable Property)

The transparency was visually evaluated by adding 3.5g of the oily liquid cleansing composition to a test tube and 0.105g of water. If it is transparent, water dissolves in the oil-based liquid cleansing composition, and the cleansing function can be exhibited. If the degree of haze is slight, a cleaning effect may be exerted. On the other hand, if the composition is white and turbid, water is in a dispersed state insoluble in the oily liquid cleansing composition and cannot exert a cleansing function. Therefore, the evaluation was made according to the following criteria.

O: is transparent

And (delta): slightly cloudy

X: white turbidity

Or the oil agent and the surfactant are not compatible or uniform, and thus the measurement cannot be performed.

TABLE 3

TABLE 4

The oily liquid cleansing compositions of examples 1to 3, in which 1, 3-butylene glycol di-2-ethylhexanoate, propylene glycol di-isononanoate and a nonionic surfactant were blended, each of which was a diester of a fatty acid having 6 to 10 carbon atoms and a glycol, had a cosmetic residual ratio of less than 50%, and were particularly excellent in the compatibility with cosmetics. On the other hand, the oily liquid cleansing compositions of comparative examples 3 to 11, which contained hydrocarbon oil liquid paraffin, ester oil cetyl 2-ethylhexanoate formed from a monobasic fatty acid and a monobasic higher alcohol, triglyceride oil glyceryl tri-2-ethylhexanoate, and a nonionic surfactant, all had a cosmetic residual ratio of 50% or more, or 80% or more, and had poor cosmetic compatibility. In addition, the measurement may not be possible because the oil agent and the surfactant are not uniformly compatible with each other. The oil-based liquid cleansing compositions of examples 1 and 3 of the present invention were excellent in all of transparency, low temperature stability (5 ℃), high temperature stability (40 ℃), easy washability, and usability by wet hands. Example 2, which contains polyoxyethylene sorbitan monostearate (20E.O.) and sorbitan monoisostearate as surfactants, has slightly poor low temperature stability (5 ℃), high temperature stability (40 ℃), easy washability, and wet-hand usability, but has excellent detergency (compatibility with cosmetics) which is the main object of the present invention. In comparative examples 4, 7 and 10 in which the same surfactant as in example 2 was used and liquid paraffin, cetyl 2-ethylhexanoate and glycerol tri-2-ethylhexanoate were blended, neither the oil agent nor the surfactant was uniformly compatible with each other. Therefore, the diester of a fatty acid having 6 to 10 carbon atoms and a glycol is more suitable for a formulation when combined with a nonionic surfactant than other oils. In comparative examples 3 and 5 in which liquid paraffin was added, the oil agent and the surfactant were not uniformly dissolved, and the cleaning function could not be measured, although the nonionic surfactant was added. Comparative examples 6 and 8, in which cetyl 2-ethylhexanoate and a nonionic surfactant were blended, were excellent in all of transparency, low temperature stability (5 ℃), high temperature stability (40 ℃), easy washability, and usability by wet hands, but as described above, the detergency (cosmetic compatibility) which is the main object of the present invention was poor. Comparative examples 9 and 11, in which glycerol tris-2-ethylhexanoate and a nonionic surfactant were blended, were excellent in transparency, low temperature stability (5 ℃ C.) and high temperature stability (40 ℃ C.), but poor in compatibility with cosmetics and washability, and in particular, poor in usability for wet hands. In addition, as shown in comparative examples 1 and 2, even when a diester of a fatty acid having 6 to 10 carbon atoms and a glycol is used, the diester is not compatible with an anionic surfactant and cannot function as a cleaning composition.

Examples

The present invention will be described in detail with reference to examples, but the present invention is not limited to these examples.

The oily liquid cleansing compositions having the compositions shown in table 5 were prepared by the same preparation method as that of the oily liquid cleansing compositions shown in tables 1to 4, and the transparency, low temperature stability, high temperature stability, cosmetic compatibility, easy washability, and usability by wet hands were evaluated by the same method as that of the oily liquid cleansing compositions shown in tables 1to 4. The results are shown in Table 5.

TABLE 5

The oily liquid cleansing compositions of examples 4 to 6, in which diisononanoic acid 1, 3-butylene diester of a fatty acid having 6 to 10 carbon atoms and a diol was blended with a nonionic surfactant, had a cosmetic residual ratio of less than 50%, and were particularly excellent in the solubility in the cosmetic. The oil-based liquid cleansing compositions of examples 4 to 6 of the present invention were excellent in all of transparency, low temperature stability (5 ℃), high temperature stability (40 ℃), easy washability, and usability by wet hands.
