Description

TITLE OF THE INVENTION DETERGENT COMPOSITION BACKGROUND OF THE INVENTION Field of the Invention: The present invention relates to a detergent composition comprising specific detergent surfactants and silicone having a specific viscosity, and, more particularly, to a detergent composition comprising an amidoamine amphoteric surfactant, a sulfosuccinate surfactant, and a non-volatile silicone. It possesses high lathering capability and excellent detergency, is only slightly irritatant to the skin and the eye, and provides excellent hair conditioning effects; e.g. easy hair-setting and combing through the hair after drying. The detergent composition is suitable for use as a shampoo, a light-duty detergent for fine fabrics such as wools, and the like.

Description of the Background Art: Anionic surfactants such as alkylsulfates, polyoxyethylenealkyl sulfates, alkylbenzene sulfonates, m- oleo in sulfonates, and the like have conventionally been used as surfactants for detergent compositions. All of them are, however, more or less irritant to the skin. Continued use of a detergent composition containing these surfactants results in chapped skin. On the other hand, amidoamine surfactants are known as excellently mild surfactants with low irritation to the skin and the eye, and thus have been used as a component for detergent compositions.

However, since amidoamine surfactants are inferior in the detergency, lathering capability, thickening effect, and conditioning effect, all of which are essential characteristics for a detergent composition, they can scarcely be used as a major surfactant for detergent compositions. Development of a detergent composition making the best use of the advantageous characteristics of amidoamine surfactants has been desired.

Sulfosuccinate surfactants are also known to be excellently mild to the skin. However, since sulfosuccinate surfactants have poor lathering capability and exhibit only an insufficient thickening effect, they are seldom used as a major surfactant component of detergent compositions and have been used merely as an auxiliary component. The use of such sulfosuccinate surfactant as a detergent component has been disclosed, for example, in Japanese Patent Publication No. 43,276/1981 which proposed a combined use of a sulfosuccinate surfactant with a conventional imidazoline amphoteric surfactant or alkylbetaine amphoteric surfactant and an N-acylamino acid salt-type anionic surfactant.

Japanese Patent Publication No. 43,479/1987 discloses a detergent composition using an ammonium sulfate of secondary alcohol ethoxylate in combination with a sufosuccinic acid half ester of secondary alcohol ethoxylate and alkylalkanolamides and/or alkylamine oxides. Furthermore, a number of patent applications have been laid-open which disclose detergent or shampoo compositions using a sulfosuccinate surfactant in combination with other detergent components; e.g. Japanese Patent Laid-open Nos.

38,395/1981, 82,895/1981, 82,897/1981, 82,898/1981, 159,897/1982, 102,996/1984, 146,864/1985, 140,514/1986, 109,897/1987, 127,396/1987, 148,599/1987, 164,797/1987, 260,893/1987, and 161,098/1988.

Although these patent applications disclose that compounds of the type used in the present invention are usable as components for detergent compositions, they do not teach nor suggest a detergent composition which make the best use of the advantageous characteristics of a sulfosuccinate surfactant, while satisfying various characteristics such as good lathering capability, excellent detergency, high thickening effect, as well as characteristics of providing a smooth pliable feeling and superb hair conditioning effect to the hair after washing.

Furthermore, Japanese Patent Laid-open No. 84,198/1987 discloses a liquid detergent composition prepared by using a monoester of sulfosuccinic acid in conjunction with a silicone derivative. Even though this patent specification claims that the detergent composition can be improved in the creaminess of lather and lather-lasting capability, the composition actually exhibits only an insufficient hair conditioning effect.

A detergent composition in which a cationic polymer is incorporated is known to exhibit an improved feeling upon use and a good conditioning effect after washing. However, an addition of such a cationic polymer to a detergent composition in an amount sufficient to exhibit a good conditioning effect and an improved feeling tends to impart a disagreeable sticky feeling while drying the hair and further entails the problem that a complex of the cationic polymer is solidified as it becomes dried, resulting in increased stiffness and hardness.

Shampoo compositions provided with a good conditioning effect by dispersing a hard silicone polymer into an anionic surfactant are disclosed in Japanese Patent Laid-open Nos.

210,022/1986, 13,012/1989, 13,013/1989, and so on. A problem in these shampoo compositions is irritation to the skin due to the anionic surfactant. Their continued use damages hair-setting due to accumulation of hard silicone polymers on the hair.

A desire has, therefore, existed for the development of a detergent composition making the best use of a low irritant surfactant, and yet possessing high lathering capability and excellent detergency, and giving excellent smoothness and pliability to the hair after washing and a superb hair conditioning effect without stickiness after drying.

In view of this situation, the present inventors have conducted extensive studies, and, as a result, found that a detergent composition comprising a specific type of amidoamine amphoteric surfactant, sulfosuccinate surfactant, and non-volatile silicone exhibited excellent detergency and lathering capability, while maintaining excellent characteristics inherent to amidoamine amphoteric surfactants and sulfosuccinate surfactants, e.g. low irritation to the skin and the eye mucosa. This finding has led to the completion of this invention.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a detergent composition comprising: (A) one or more amidoamine amphoteric surfactants; (B) one or more sulfosuccinate surfactants; and (C) a non-volatile silicone having a viscosity of 515,000,000 cSt at 250C.

Other objects, features and advantages of the invention will hereinafter become more readily apparent from the following description.

DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS Given as examples of amidoamine amphoteric surfactants are compounds represented by the following formulae (I) and (if):

wherein R1 and R3 independently represent a saturated or unsaturated hydrocarbon group having 7-19 carbon atoms, R2 and R4 independently represent a group -CH2COOM1, -CH2CH2COOMl, or

wherein M1 represents a hydrogen atom, alkali metal, or an alkanolamine, and R5 represents a hydrogen atom, a group -CH2COOM1, -CH2CH2COOM1, or

wherein M1 has the same meaning as defined above.

Specific examples of preferable compounds represented by formula (I) are N-lauroyl-N'-carboxymethyl-N'-(2 hydroxyethyl ) ethylenediamine, N-lauroyl-N' -carboxyethyl-N' - (2-hydroxyethyl)ethylenediamine, N-myristoyl-N' - carboxymethyl-N'-(2-hydroxyethyl)ethylenediamine, N-myristoyl-Nt-carboxyethyl-N'-(2-hydroxyethyl)- ethylenediamine, N-palmitoyl-N'-carboxymethyl-N'-(2 hydroxyethyl ) ethylenediamine, N-palmitoyl-N' - carboxyethyl N'-(2-hydroxyethyl)ethylenediamine, and the like, as well as their salts. Enumerated as specific examples of preferable compounds represented by formula (II) are N-lauroyl-N-(2 hydroxyethyl ) -N' -carboxymethyl-ethylenediamine, N-lauroyl-N-(2-hydroxyethyl)-N',Nt-bis(carboxymethyl)- ethylenediamine, N-lauroyl-N-(2-hydroxyethyl)-N',N'- bis(carboxyethyl)ethylenediamine, N-myristoyl-N-(2 hydroxyethyl) -N' -carboxymethyl-ethylenediamine, N-myristoyl-N-(2-hydroxyethyl)-N',N'-bis(carboxymethyl)ethylenediamine, N-myristoyl-N-(2- hydroxyethyl)-N',N'bis(carboxyethyl)ethylenediamine, N-palmitoyl-N-(2 hydroxyethyl ) -N' carboxymethyl-ethylenediamine, N-palmitoyl-N-(2-hydroxyethyl)-N',N'-bis(carboxymethyl)ethylenediamine, N-palmitoyl-N-(2-hydroxyethyl)-N',N'- bis(carboxyethyl)ethylenediamine, as well as their salts.

The salt may be a salt of an alkali metal, e.g. sodium; a salt of an alkaline earth metal, e.g. magnesium; a salt of alkanolamine, e.g. triethanolamine; or an ammonium salt.

Since these salts often contain inorganic salts as impurities, they are desalted to remove a part or all of the inorganic salts to the extent that a content of impurity inorganic salts is less than 1% by weight to produce purified organic salts.

A desalted amidoamine amphoteric surfactant may be adjusted by means of solvent extraction, electrodialysis, or the like methods. A particularly preferable amidoamine amphoteric surfactant is an ammonium or triethanolamine salt of secondary amidoamino acid of formula (Ia) shown below, in which the content of impurity inorganic salts is less than 18 by weight. By using such an ammonium or triethanolamine salt, a polymer which is soluble in water and insoluble in a concentrated inorganic solution, e.g. in a 2% sodium chloride solution, can easily be incorporated in a detergent composition in an amount of 0.05-108 by weight.

Here, the polymers which are soluble in water and insoluble in a concentrated inorganic solution are, for example, cationic polymers such as cationic cellulose, cationic starch, cationic natural gum, diallyl quaternary ammonium salt homopolymer, and the like, which can provide a conditioning effect to the skin, the hair, or fabrics; anionic polymers such as alginic acid, carboxymethyl cellulose, carboxyvinyl polymer, and the like, which can provide a thickening effect; and nonionic polymers such as hydroxyethyl cellulose, polyvinyl alcohol, polyvinyl pyrrolidone, polyethylene oxide, and the like, which can provide a thickening effect and an excellent feel to the hair and skin.

A process for the preparation of amidoamine amphoteric surfactants used in the present invention are described, for example, in Japanese Patent Laid-open No. 115,512/1985.

The amidoamine amphoteric surfactants can be used singly or as a mixture of one or more of them, and preferably incorporated in the detergent composition of the present invention in an amount of 1-45% by weight, and particularly preferably 5-30% by weight.

Given as examples of sulfosuccinate surfactants, which are component (B) of the present invention, are sulfosuccinates of higher alcohols or their ethoxylates,or sulfosuccinates derived from higher fatty acid amides represented by formula (III) or (IV):

wherein R6 represents a group

(wherein R7 represents a linear or branched alkyl or alkenyl group having 8-22 carbon atoms, R8 represents a hydrogen atom or a methyl group, Rg represents a linear or branched alkyl or alkenyl group having 7-21 carbon atoms, and m denotes a value of 0-20), and M2 represents a hydrogen atom or a cationic ion which can produce a water-soluble salt and is selected from alkali metals, alkaline earth metals, ammonium, and organic ammonium.

Of the compounds represented by formula (III) or (IV), typical sulfosuccinates of higher alcohol or its ethoxylate are disodium salt of sulfosuccinate of a secondary alcohol having 11 to 13 carbons [Softanol MES 3, 5, 7, 9, 12, manufactured by NIPPON SHOKUBAI KAGAKU KOGYO CO., LTD (each number denotes an average addition mol of ethylene oxide (EO))], di-sodium salt of sulfosuccinate of lauryl alcohol or lauryl alcohol ethoxylate (EO=3, 4, 6, 9, 12, Kohacool L-400, etc., manufactured by Toho Chemical Industries Co., Ltd.), di-sodium salt of sulfosuccinate of synthetic primary alcohol with a C12-15 carbon atom content or its ethoxylate (EO=2-12), di-sodium salt of sulfosuccinate of Guerbet alcohol with a C8-22 carbon atom content or its ethoxylate (EO=2-12), and the like.Given as examples of the sulfosuccinates derived from a higher fatty acid amide are di-sodium salt of sulfosuccinate of polyethylene glycol (EO=1, 2) amide laurate, di-sodium salt of sulfosuccinate of polyethylene glycol (EO=1, 2) oleate, di-sodium salt of sulfosuccinate of coconut oil fatty acid polyethylene glycol (EO=4), and the like. Among these, linear higher alcohol mono succinate with a Cll-13 carbon atom content is preferable in view of an agreeable feeling and lathering capability.

These sulfosuccinate surfactants can be used either singly or as a mixture of one or more of them, and preferably incorporated in the detergent composition of the present invention in an amount of 1 to 45% by weight, and particularly preferably 2 to 20% by weight.

The total amount of amidoamine amphoteric surfactants and sulfosuccinate surfactants to be incorporated into the detergent composition of the present invention is preferably 5 to 50% by weight, with 10 to 30% by weight being particularly preferable. The proportion of amidoamine amphoteric surfactants and sulfosuccinate type surfactants may be arbitrarily selected from the range of 1:9 to 9:1.

The range of 1:4 to 4:1 is particularly preferable.

Examples of non-volatile silicone derivatives, component (C) of the present invention, are those having a viscosity of 5-15,000,000 cSt at 250C, e.g.

dimethylpolysiloxane, methylphenylpolysiloxane. These silicone derivatives may be used either singly or as a mixture of two or more of them, and incorporated in the detergent composition of the present invention in an amount of 0.01-10% by weight, preferably 0.5-8% by weight, and particularly preferably 1-5% by weight. If the amount is less than 0.01% by weight, only an insufficient conditioning effect is obtained, while if the amount is greater than 10% by weight, lathering capability is impaired. A mixture of silicone derivatives having various viscosities can be used for the detergent composition of the present invention.

From the aspect of a better conditioning effect, silicone derivatives having a viscosity of 5,000-15,000,000 cSt, and particularly 1,000-15,000,000 cSt, singly or as a mixture, are preferable. Volatile silicone derivatives having a viscosity less than 5 cSt provides only an insufficient feeling upon use. Silicone derivatives having a viscosity greater than 15,000,000 cSt are difficult to handle because of the high viscosity. They may be accumulated on the hair during repeated use, resulting in an impaired hair-setting effect. The viscosity of these silicone derivatives are measured at 250C by means of a Bruckfield rotary viscometer according to Cosmetic Material Standard, Vol 2, General Experiment, Viscosity Measuring Method No. 2.

In addition to the above essential components, other components commonly used in detergent compositions may optionally be incorporated into the composition of this invention to the extent that the effects of the invention are not impaired.
