DETAILED DESCRIPTION OF INVENTION

[0034] The present invention provides personal care formulations which are particularly useful in depositing silicone personal care ingredients on hair fibers much like polyquaternium ingredients and cationic guar. The cationic starches of the invention have been found to provide improved conditioning properties to cosmetic and dermatologically acceptable personal care compositions. Of particular interest to the present invention is the fact that the cationic starches being used are generally unthinned and are used at molecular weights close to those of their native starches. This is in contrast to prior art formulations which generally use thinned and sometimes significantly thinned starches. Not only do the personal care formulations of the invention provide similar or superior functionality to commercially-available polyquaternium and cationic guar formulations they are further characterized by superior solubility profiles and higher or comparable bio-based contents than prior art products.

[0035] According to one aspect of the invention the cationic starch ingredients derived from potato, rice, waxy rice, and waxy corn not only enhance the deposition of silicone conditioning polymers but surprisingly provide conditioning benefits when used without any added silicone. Not only do the personal care formulations of the invention provide similar or superior functionality to commercially available polyquaternium and cationic guar formulations they are further characterized by superior solubility profiles and comparable or higher bio-based contents than prior art products. According to a further surprising aspect of the invention it has been found that cationic starches derived from mung bean, potato, rice and starches provide desirable conditioning properties to personal care compositions which are free of silicone polymers.

[0036] According to one aspect of the invention a personal care formulation is provided comprising: water; a personal care ingredient and a cationic starch characterized by: a) an amylopectin/amylose weight ratio of greater than or equal to 60/40; b) an apparent cationic molecular weight of greater than or equal to 12 million daltons; and c) a cationic degree of substitution of from 0.5 meq/g to 2.5 meq/g. Suitable cationic starches for use in the invention include selected those from the group consisting of potato, rice, waxy rice, and waxy corn having the desired amylopectin/amylose ratios and apparent cationic molecular weights.

[0037] According to a further aspect of the invention cationic mung bean starch which is characterized by a cationic molecular weight of about 10 million daltons but has an amylopectin/amylose ratio of close to 60/40 is also surprising useful in personal care formulations and can be used not only to enhance the deposition of silicone polymers and improve their conditioning effects but also to replace silicone polymers and provide silicone-free personal care compositions with improved conditioning properties

[0038] According to one aspect of the invention a particularly useful dry, cationic potato starch for personal care conditioning applications is produced which falls under CAS#56780-58-6. The starch has a positive charge density that can vary from 0.7 and 2.5 meq/g. It is an alternative to naturally derived Polyquaternium-10, CAS# 81859-24-7 and Cationic guar, CAS# 65497-29-2 as well as synthetic cationic polymers such as Polyquaternium-6 (PQ-6) and Polyquaternium-7 (PQ-7) and the like.

[0039] The personal care compositions of the invention include those of the “rinse off” category such as shampoos, rinse-off conditioners, body washes, facial washes, liquid and bar soaps, hydro-alcoholic based products such as hand sanitizers and the like which can be readily washed off with water and those categorized as “leave-ons” such as sunscreen, lotions, combing creams, insect repellants and the like which are intended to remain on the skin or hair for an extended period. Additional leave-ons include color cosmetics such as pigmented skin colorants, nail polish and nail polish remover, mascara, rouge, lipstick and balm.

[0040] The cationic starch components of the invention are combined with cosmetic or dermatological ingredients in cosmetically or dermatologically acceptable media which are compatible with application to keratinous substances such as skin and hair. The compositions preferably have a pH of from about 1 to about 13 and more preferably from 2 to 12 but those of ordinary skill in the art would understand to select a pH most compatible with the body part to which the compositions are being applied and the components within the personal care ingredients.

[0047] Still other suitable anionic surfactants are the reaction products of fatty acids esterified with isethionic acid and neutralized with sodium hydroxide where, for example, the fatty acids are derived from coconut oil or palm kernel oil, and sodium or potassium salts of fatty acid amides of methyl tauride where, for example, the fatty acids are derived from coconut oil or palm kernel oil.

[0048] Other anionic surfactants suitable for use in the shampoo compositions are the succinnates, examples of which include disodium N-octadecylsulfosuccinnate, disodium lauryl sulfosuccinate, diammonium lauryl sulfosuccinate, tetrasodium N-(1,2-dicarboxyethyl)-N-octadecylsulfosuccinnate, diamyl ester of sodium sulfosuccinic acid, dihexyl ester of sodium sulfosuccinic acid, and dioctyl esters of sodium sulfosuccinic acid.

[0049] Other suitable anionic surfactants include olefin sulfonates having about 10 to about 24 carbon atoms. In this context, the term “olefin sulfonates” refers to compounds which can be produced by the sulfonation of alpha-olefins by means of uncomplexed sulfur trioxide, followed by neutralization of the acid reaction mixture in conditions such that any sulfones which have been formed in the reaction are hydrolyzed to give the corresponding hydroxy-alkanesulfonates. The alpha--olefins from which the olefin sulfonates are derived are mono-olefins having from about 10 to about 24 carbon atoms, preferably from about 12 to about 16 carbon atoms. Preferably, they are straight chain olefins.

[0050] Another class of anionic surfactants suitable for use herein is the beta-alkyloxy alkane sulfonates. These surfactants conform to the formula:

Publishing Co.

[0053] The surfactants are preferably included in the formulations at concentrations below 35%, more preferably 20% and most preferably below 15%. Other optional ingredients include compounds and mixtures that modify the aesthetics of the final composition. Fragrances and natural oils may be used to provide a desirable odor while dyes, pigments, opacifying or pearlescent agents can be used to impart a more appealing appearance. From a performance perspective, silicones can be employed to impart a conditioning benefit such as reduced wet combing force or enhanced shine, while Vitamins, amino acids and humectants can provide enhanced protective and reparative functionality. Of particular utility are ingredients designed to protect, prolong or enhance the intensity of hair colorants or skin and nail coloring compositions.

EXAMPLES

[0064] The conditioning properties of a standard shampoo composition containing various cationic substituted starches were evaluated. All testing was performed on hair procured from International Hair Importers & Products (Glendale, NY). The hair tresses weighed approximately 3 g and measured 8″ in length and 1″ in width. Prior to testing, the tresses were bleached using a 6% hydrogen peroxide at a pH of 10.2. The tresses were left in contact with the bleach solution for 40 minutes under controlled temperature conditions (40° C.). At the end of this process, tresses were thoroughly rinsed under an Intellifaucet rinsing apparatus set at 40° C. with a controlled flow rate of 1.0 GPM. Various shampoo formulations with and without Silicone were produced and tested.

[0067] All product treatments were conducted according to the following procedure: Shampoo was applied at a quantity of 0.1 g/g of hair of shampoo applied to tress of wet hair and massaged in between thumb and forefinger for thirty (30) seconds. The tress is then rinsed under Intellifaucet rinsing apparatus set at 38° C. and 1gal/min for 30 seconds.

Wet Combing Force

[0068] The primary technical function of most conditioning products is to lubricate the hair surface; and, in doing so, facilitate manageability and provide detangling benefits and lower combing friction. A common and highly consumer-relevant approach for measuring this lubrication involves an instrumental combing experiment. Testing involves use of an Instron brand tensile tester to measure frictional forces while a hair tress is pulled through a comb. Wet combing force was measured by testing eight (8) tresses (each 3.0 g, 8in in length) were used per treatment group. The tests are carried out in accordance with the method first proposed by Garcia & Diaz (JSCC, 27, (1976) 379-398 - Combability Measurements on Hair). Combing experiments were performed in the wet state after treatment. Six (6) measurements were taken per swatch using an Instron brand tensile tester to evaluate product performance and are reported in units of Grams of Force (gF) where 1 gF equals about 0.0098 Newtons.

Shine

[0069] The commercially-available Samba device by Bossa Nova was used to quantify shine on hair tresses. The equipment operates in accordance with a collection of referenced literature articles (e.g. Bustard & Smith, Appl.Optics, 30, (1991), 3485; McMullen and Jachowicz, JSCC, 54, (2003), 335; McMullen and Jachowicz, JSCC, 55, (2004), 29) whereby the ratio of polarized and non-polarized light reaching the detector as an indicator of specular and diffuse reflection. These two values can then be employed in accordance with any of the equations in the scientific literature to produce numerical shine values.

[0070] The intensity, breadth and contrast of the shine bands on the hair affect the impression of shine and are quantified as shine indices which are calculated from the measurement in the Samba device. These phenomena may be affected by hair color, reflectivity of the fibers’ surface as well as the degree of alignment of the hair fibers. A commercial tress holder that does not impose a manual alignment of the hair fibers was used to allow this to be a driving variable between samples. Consequently, devices that provide a higher degree of alignment may yield a higher shine index. In all instances, four shine measurements were performed on each tress, with eight replicate tresses being used per sample to ensure statistical relevance. All experiments were performed on bleached hair. The shine data show that use of the ingredients of the invention does not adversely affect shine.

[0071] The wet combing results of conventional shampoo formulations including sulfates (the Miracare® LSC-217 shampoo base) containing cationic starches are show in Tables 1A, 1B, 2 and 3 below and in FIGS. 1 and 2. The results in FIGS. 1 and 2 are shown using box & whisker plots using Statistica™ while JMP™ analytical software was used to perform the statistical analysis. Statistics were performed using the student’s t-test at the 95% confidence level.

[0073] The shampoo comprising 615-149A cationic potato starch gave rise to substantially lower combing forces when compared with Polyquaternium-10 (Dow U-Care™ Polymer JR-400) and has the lowest wet combing force and shows a decrease in wet combing force of approximately 48% when compared to treatment Polyquaternium-10 only.

[0074] Shampoo compositions with and without silicone comprising cationic potato starch with medium (1.33 meq/g) and high (1.99 meq/g) charges and cationic mung bean starch with a medium cationic charge (1.39 meq/g) according to the invention were tested against shampoos made with Polyquaternium-10 (Dow U-Care™ Polymer JR-400) and with cationic guar gum (Ashland N-Hance™ 3196) for mean combing force with the results shown in Table 4 below.

[0075] The results show that the formulations of the invention provide combing qualities superior to compositions comprising polyquaternium-10 and roughly equivalent to those provided by cationic guar gum.

[0076] Sulfate-free shampoo formulations using the Miracare® Plaisant formulation described above were also tested according to the above-described protocol with sample 615-130B comprising cationic guar gum, 615-145B comprising highly charged cationic potato starch and sample 615-149A comprising medium charged potato starch. The results shown in FIG. 3 demonstrate a trend of lowered combing forces for the cationic potato and waxy corn compared with cationic guar gum containing formulations.

[0077] Shampoo formulations using the Miracare® LSC-217 formulation described above were tested in accordance with the methods described above with samples 615-130B comprising cationic guar gum, 615-145B comprising highly charged cationic potato starch, 615-147A comprising cationic mung bean starch and 615-149A comprising medium charge waxy dent starch but comprising reduced levels of the test polymer (0.5% wt.) and (0.2% wt.) with the results shown in FIGS. 4 and 5. Those results show that the compositions of the invention provide wet combing results roughly equal to those of the cationic guar control.
