Description

Hair care compositions comprising sucrose polyesters

Technical Field

The present invention relates to hair care compositions for delivering conditioning benefits and comprising sucrose polyesters.

Background

Human hair becomes dry and/or damaged due to the surrounding environment, styling, drying and/or coloring or otherwise chemically treating the hair.

Various methods have been developed to condition hair. A common method of providing conditioning benefits is to employ hair care compositions comprising conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point fats and oils, silicone compounds, and mixtures thereof. Silicones are commonly used as conditioning actives for many hair care compositions. However, the rising cost, inefficient conditioning of damaged hair, and petroleum-based nature of silicones have minimized their desirability as conditioning actives.

Based on the foregoing, there is a need for conditioning actives that can provide conditioning benefits to hair that can be used in place of or in combination with silicones or other conditioning actives to maximize the conditioning activity of hair care compositions. Furthermore, there is a need to find conditioning actives that are capable of delivering conditioning benefits to damaged hair that has previously been difficult to condition with conventional conditioning actives. Finally, there is a need to find conditioning actives that can be derived from natural sources, thereby providing conditioning actives derived from renewable resources.

None of the prior art provides all of the advantages and benefits of the present invention.

Furthermore, the hair care compositions of the present invention deliver different, cleaner and/or softer softness than traditional silicones. Each of these components, as well as other related components, is described in detail below.

I. Sucrose polyesters

The hair care compositions of the present invention comprise one or more types of sucrose polyesters (also referred to herein as "sefoses"). Sucrose polyesters are derived from natural sources and therefore the use of sucrose polyesters as conditioning actives can have a positive environmental impact.

Sucrose polyesters are polyester materials with multiple substitution sites around the sucrose backbone in combination with chain length, saturation and derivatized variants of fatty chains. The sucrose polyester showed a range of degrees of esterification and saturation as shown in figure 1.

The sucrose polyesters of the present invention have a degree of esterification ("IBAR") greater than about 5. In one embodiment, the sucrose polyester may have an IBAR of from about 5 to about 8. In another embodiment, the sucrose polyester has an IBAR of about 5 to 7, and in another embodiment, the sucrose polyester has an IBAR of about 6. In another embodiment, the sucrose polyester has an IBAR of about 8. Since the sucrose polyester is derived from natural sources, there may be a distribution and chain length of IBAR. For example, a sucrose polyester having an IBAR of 6 may comprise predominantly about 6 IBAR, and a mixture of some about 5 IBAR and some about 7 IBAR. In addition, the sucrose polyesters of the present invention may have a saturation or iodine value ("IV") of about 3 to about 70. In another embodiment, the sucrose polyester of the present invention may have an IV of about 3. In another embodiment, the sucrose polyester of the present invention may have an IV of about 40. The sucrose polyesters of the present invention have a melting point greater than about 30 ℃. In addition, the sucrose polyesters of the present invention have a chain length of about C12-C14, and may contain some C16 for sucrose polyesters having IBAR of about 5 to about 7. For sucrose polyesters with an IBAR of about 8, the chain length is about C16-C18.

In another embodiment, the conditioning active comprises one or more sucrose polyester blends comprising two or more sucrose polyesters, wherein at least one sucrose polyester has a melting point greater than about 30 ℃, an IBAR greater than about 5, an IV of about 3 to about 70, and at least one sucrose polyester has an IBAR between about 1 and about 8, and an IV between about 1 and about 135, and wherein the sucrose polyester blend has an IBAR of at least 5 and an IV of about 1 to about 135. In one embodiment, the sucrose polyester blend is in a ratio of about 1: 1; in another embodiment, the sucrose polyester blend is in a ratio of about 1: 2; in another embodiment, the sucrose polyester is in a ratio of about 1: 3; in another embodiment, the sucrose polyester is in a ratio of about 1: 5; in another embodiment, the sucrose polyester is in a ratio of about 3: 4; and in another embodiment, the sucrose polyester is a sucrose polyester having a melting point greater than about 30 ℃, an IBAR of greater than about 5, an IV of about 3 to about 70, and a ratio of sucrose polyester having an IBAR between about 1 and about 8, and an IV between about 1 and about 135 of about 3: 10. In one embodiment, the sucrose polyester blend has a G' value at 0.01Hz of from about 0.22Pa to about 10,030 Pa. Further, in one embodiment, the sucrose polyester blend has a G "value at 0.01Hz of from about 0.83Pa to about 23,960 Pa.

Table 1 reports the average values of G' and G "from 0.01Hz up to 100Hz for different blends of sucrose polyesters with melting points greater than about 30 ℃, IBAR greater than about 5, IV from about 3 to about 70 (Sefose 1618H, P & G Chemicals) and sucrose polyesters with IBAR between about 1 and about 8, and IV between about 1 and about 135 (Sefose 1618U, P & G Chemicals). The blends were prepared by formulating the amount and type of sucrose polyester in a stainless steel beaker heated at about 75 ℃ in a water bath at the specified ratio. At this temperature, any solid sucrose polyester present in the blend melts and intimately mixes with all other sucrose polyesters to form a homogeneous mixture. After this time, the beaker was removed from the water bath and allowed to cool to room temperature. Samples from these blends were transferred to a rheometer for measurement of G' and G ".

TABLE 1

Examples of sucrose polyesters suitable for use in the present invention include, but are not limited to, Sefose 1618H, Sefose2275C, 1618S, both available from Procter and Gamble Co.

The following data (shown in table 2) show that sucrose polyesters have the above-described characteristics associated with conditioning that deliver dry-comb benefits over those of sucrose polyesters that do not have the above-described characteristics. For example, Sefose C1618IB6IV85 has a lower dry combing benefit than Sefose C1618IB6IV40 and IV 56, and Sefose C1618IB6IV 3. In addition, Sefose C1618IB8IV135 and Sefose C1618IB8IV85 have lower dry combing benefits than Sefose C1618IB8IV38, Sefose C2275IB8IV5, and Sefose C1618IB8IV 3.

Low-lying Hair (Low Lift Hair) easy-to-dry comb-body

In addition to use in hair care compositions, the sucrose polyesters of the present invention can be beneficially used as conditioning agents in personal care compositions, especially personal cleansing compositions such as body washes.

Conditioning benefits

Silicones have traditionally not been as effective in conditioning damaged hair or low-voltage hair as undamaged hair. Low-voltage hair includes hair that has been exposed to bleach or other coloring agents. Hair care formulations, particularly shampoo formulations, comprising the sucrose polyesters of the present invention alone or in combination with silicone conditioning actives deliver improved dry comb benefits to damaged or low voltage hair. The addition of silicone, in particular particulate silicone, increases the combing benefit. The silicone and sucrose polyesters do not offset each other. Tables 3-4 below show that sefoses in the cleansing shampoo base have better dry combing benefit (which is associated with conditioning benefit) than the cleansing shampoo alone for low lying hair and virgin brown hair. Furthermore, tables 3-4 below show that Sefosen combined with particulate silicone in a cleansing shampoo base is nearly equivalent in dry combing benefit to cleansing/Si conditioners used as low-voltage hair conditioners, and equivalent in dry combing benefit to cleansing/Si conditioners used for virgin brown hair. The formulations described in tables 3-4 are seen in tables 5-7.

Method for producing shampoo preparations

Any suitable method of preparing a shampoo of the invention may be used.

A typical procedure for a cleansing shampoo is to mix the undecyl sulfate paste or undecyl polyether sulfate paste, or mixtures thereof, with water, add the desired water soluble co-surfactant and obtain the composition by adding preservatives, pH control agents, perfume and salt to obtain the target physical characteristics. If a water-insoluble co-surfactant is desired, the mixture of surfactant and water can be heated to a suitable temperature to facilitate their blending. If a rheology modifier is desired, it can be added to the surfactant mixture prior to the final step.

In the case of conditioning shampoos, the surfactant paste is typically mixed with a co-surfactant as above and diluted with water to a comparable target level to achieve final activity. At this point, the rheology modifier may be added followed by conditioning agents such as sucrose polyesters, silicone or silicone emulsions or other oils, cationic polymers from polymer premixes, perfumes, pearlizing or opacifying agents, perfumes, and preservatives. Suitable mixing steps can be used as required to ensure homogeneity. The product is completed by adding a pH control agent, a hydrotrope, and a salt to the desired physical characteristics.

Concentrated formulations are formulations that deliver the same benefit to the consumer at lower usage levels. Concentrated formulations and methods of making concentrated formulations are described in U.S. patent provisional application serial No. 61/011631 filed 1/18/08.

Method for preparing concentrated preparation

To achieve surfactant activity levels that result in 1/3 products at typical shampoo weight or volume levels, it is desirable to use one or more components derived from the more highly active lamellar phase paste. These materials can include, but are not limited to, SLE (1) S, C11E (1) S, C13-15 alkanesulfonates as the flowable fluid. Isotropic pastes containing concentrated C10 content (38%) C11S (35%) and higher SLS activity can also be prepared to facilitate these formulations. In a typical process, the isotropic paste may be mixed with a co-surfactant, a preservative and the desired amount of lamellar phase paste. This can be mixed on a Flak Tek speed mixer until homogeneous. The pearlescent agent dispersion (EGDS), cationic polymer and perfume were added and mixed again until a homogeneous mixture was obtained. Finally, the sucrose polyester, silicone emulsion, additional preservatives and pH control agents are mixed with milder agitation to obtain the desired end product mixture.

The conditioning compositions of the present invention are particularly suitable for use in rinse-off conditioners. Such compositions are preferably used by the following steps:

(i) after shampooing, applying an effective amount of the conditioning composition to the hair to condition the hair; and

(ii) the hair is then rinsed.

Test method

G 'and G' test methods

The process provides G' and G "values for a given sucrose polyester blend composition. Each blend was carefully transferred to a rheometer plate while avoiding the application of intense shear to each blend composition.

A suitable Rheometer for use in the method is a Haake RS-150RheoStress Rheometer, connected to a computer with suitable data recording and analysis software. The test was performed at a temperature of 35 ℃ and an equilibration time of 3 minutes. The rheometer was set with a 35mm diameter, 4 degree steel cone, as measured from the center of the cone, to a gap of 140 μm across the plate. Angular frequency was applied, starting at 0.01Hz, where G 'and G "were measured three times and the average of G' and G" was recorded with the software. Similarly, these measurements were repeated at each decade after 0.01Hz and up to 100 Hz. All measurements were performed under a constant stress of 1 Pa.

Wet conditioning and dry conditioning test methods

This test method is intended to enable subjective assessment of the essential performance of conditioning shampoos in terms of wet and dry combing efficacy. The control treatment was a cleansing shampoo using only surfactant and no conditioning material, and this same shampoo was used in the wash process, followed by application of a medium range of hair conditioner. These treatments enable easy differentiation of the performance of a range of prototype conditioning shampoos. In a typical test, the performance of 3 to 5 individual formulations can be assessed. The substrate was brown virgin hair from multiple sources, which was screened to ensure uniformity and no significant surface damage.

Treatment step

Five hair switches weighing 4 grams and 8 inches long were combined in a hair switch holder and wetted with water at 40 c and typical hardness (9-10gpg) for ten seconds under rubbing to ensure complete and uniform wetting. The switches were slightly water-removed and the product was applied evenly along the length of the combined switches from one inch below the holder to the end at an amount of 0.1g product per gram of dry hair (0.1g/g hair, or 2g/20g hair). For more concentrated stock solutions, the level used was reduced to 0.05g/g of hair. The switch combination was allowed to foam for 30 seconds by a rubbing motion typical for consumers and then rinsed with 1.5L/min (1.5gal/min) of flowing water at 40 ℃ for 30 seconds (while rubbing the hair) to ensure complete cleaning. This step is repeated. When the conditioner is applied, it is applied to the hair switch combination in the same manner as the shampoo above, the hair switch combination is thoroughly rubbed and rinsed thoroughly under rubbing. The switches were slightly dewatered, separated from each other, hung on a hanger so that they did not touch, and smoothed with a wide-tooth comb.

Rating step

For wet comb evaluation with a professional grader, the switches on the rack were divided into five groups, one switch from each treatment being included in the rating group. Only two combing assessments were performed for each switch. The raters were asked to compare the treatments by combing with narrow-tine nylon combs, typical of those used by consumers, and rated for ease/combability on a scale of zero to ten. Ten separate assessment results were collected and the results were analyzed with a statistical analysis package to determine statistical significance. Control charts are often used to ensure that low and high control data are sorted into their regular domains. Statistical significance of differences between treatment agents was determined using Statgraphics Plus 5.1. All conditioning stock had to be two more LSDs than the cleansing control to be considered acceptable.

For dry combing evaluation, the switches from above were transferred to a temperature and humidity controlled room (72F/50% RH) and allowed to dry overnight. They were kept separate as above and panelists were asked to rate dry conditioning performance by making three assessments; ease of drying and combing in the middle of the switches, ease of drying and combing of the tips, and sensory evaluation of the tip feel. For these controls, the same ten point scale was used. Likewise, only two panelists rated each switch group once. Statistical analysis of score gaps was performed using the same method as above.
