Description

[0001]P0000785CPL WASH COMPOSITION WITH ANIONICS HAVING REDUCED PALM KERNEL OIL RE-LIANCE Field of the Invention 5The present invention is directed to a wash composition having a reduced amount of palmkernel oil derived anionic surfactant. More particularly, the invention is directed to a washcomposition comprising anionic surfactant which is a C16-C20 lactylate, a C16-C20 glycolateor a mixture thereof. The composition is surprisingly stable, and unexpectedly, providesexcellent sensory and lathering characteristics. The wash composition of the present in- 10 vention is suitable to be formulated substantially free of at least one of a sulfate-basedsurfactant, paraben, hydantoin, isothiazolinone, phthalate, dye, dioxane, soap and sili-cone oil. Background of the Invention Wash compositions are typically employed to cleanse skin and to reduce shine associated15 with sebum produced in specialized epithelial cells known as sebocytes. They are alsoused to minimize bacteria on the hands and face such that washing is viewed as the most effective way to prevent the spread of germs and bacteria. In fact, experts believe that pe- riodic washing throughout the day can reduce the number of consumers catching colds by about 50%. In addition to skin, wash compositions are conventionally used on hair and to20 clean objects within the home, like counters, windows, and clothes.Consumers prefer compositions that are mild, especially on skin and hair, and they alsodemand compositions that are more favorable to the environment. Particularly, use ofless palm kernel oil is desired by consumers and environmentally conscious companies since less palm kernel oil usage invariably leads to a reduction in global deforestation.25 The present invention, therefore, is directed to a wash composition having a reduced amount of palm kernel oil derived anionic surfactant. More particularly, the invention isdirected to a wash composition comprising anionic surfactant which is a C16-C20 lactylate,a C16-C20 glycolate or a mixture thereof. The composition is stable, and unexpectedly,30 provides excellent sensory and lathering characteristics, and surprisingly, with longer chain C16-C20anionic surfactants. The wash composition of the present invention is P0000785CPL suitable to be formulated substantially free of at least one of a sulfate-based surfactant, paraben, hydantoin, isothiazolinone, phthalate, dye, dioxane, soap and silicone oil.Additional Information Efforts have been disclosed for making wash compositions.

In a fourth aspect, the invention is directed to the use of C16 -C20 lactylate or C16 -C20 glyco-late or both with additional anionic surfactant, and zwitterionic and / or amphoteric surfac-tant to yield a wash composition having reduced palm kernel oil reliant surfactant and su- 25 perior lather characteristics. All other aspects of the present invention will more readily become apparent from the de- scription and Examples which follow. Skin, as used herein, is meant to include skin on the arms (including underarms), face, 30 back, feet, neck, chest, hands, legs, buttocks and scalp (including hair). Stable means thecomposition of the invention has initial viscosity (i.e., viscosity taken within 24 hours of thecomposition being made) that changes by no more than 15% after being stored for 1 P0000785CPL month, and preferably, 2 months at 45°C. Stable also means that after being stored at45°C for one month, and preferably, 2 months, wash compositions consistent with the in-vention display no malodor, color change, syneresis, or precipitate. Palm kernel oil derived or reliant means a component like a surfactant having a fatty por-5 tion with a hydrophobic chain that is a saturated hydrocarbon recovered from palm kerneloil and including components having a hydrophobic portion derived from lauric and myristic acid or their alcohol or amide derivatives. For the avoidance of doubt, lamellar, asused herein, means having layers of surfactant arrangement where polar head groups align with water to shield fatty acid acyl chains from the water such that over 85% (or 90 to10 100% or 100%) of the total surfactants in the composition are arranged as micelle plates or layers creating a translucent or opaque composition. In contrast, isotropic means acomposition with micelles arranged without directional preference. Transparent means clear and able to see through. Translucent means not opaque, and therefore, permitting light to pass through with diffusion. The wash composition of the present invention is pref- 15 erably isotropic. Soap, as used herein, means salt of a fatty acid. Zwitterionic means a dipolar ion, having a positive and negative charge. Amphoteric means a component like a surfactant that is positively charged in an acidic solution and negatively charged in in an alkaline solution. 20 In the present invention, it has been unexpectedly discovered that use of C16-C20lactylate and / or glycolate which is not required to be dependent on hydrocarbon chain derived from palm kernel oil can be used to replace a portion of traditional C10-C14anionic surfactants, and especially, C12-C14 anionic surfactants derived from palm kernel oil. The wash compo-sition of the present invention is one which, as noted, has a viscosity of at least 5 mPa-s25 where viscosity is taken at 25°C with a Discovery HR-2 Rheometer using sand blastedplates having a 1000-micron gap and a shear rate of 4 s-1.

In an embodiment of the inven- tion, the wash composition can have a viscosity from 500 to 225,000 mPa-s, and most P0000785CPL preferably, from 2,500 to 180,000 mPa-s (or 3,000 to 125,000 mPa-s or 5,000 to 90,000 mPa-s or 6,000 to 15,000 mPa-s). When used for hand applications, the wash composi- tion of the present invention will preferably have a viscosity that is at least 500 mPa-s and not higher than 7,000 mPa-s. 5 The wash composition of this invention may, optionally, comprise medicinal or therapeutic agents, but preferably, is a wash which is for cosmetic and non-therapeutic uses to re- move dirt, oil, make-up or the like from surfaces, including skin. In a preferred embodi-ment, the wash composition is a personal wash composition, and therefore, a liquid body10 wash for use while showering or bathing.

The packaging preferably is biodegradable and / or is prepared from recycled materials including post-consumer resins. Other suitable formats include impregnating the wash composition in nonwovens like those having cotton, poly- ester or both or by providing the wash composition in water soluble sachets such as those 5 essentially consisting of polyvinyl alcohol. The Examples are provided to facilitate an understanding of the invention. They are not intended to limit the scope of the claims. All Samples (surfactant mixes (Table I) and isotropic wash compositions (Table II)) in the Examples were prepared by mixing ingredients with moderate shear, with temperature 10 varying between about 30°C about 80°C and pressure being atmospheric. The amountspresented are based on total amount (weight%) added. Viscosity (in millipascal second)measured with a Discovery HR-2 Rheometer using sand blasted plates having a 1000-mi-cron gap and a shear rate of 4 s-1with temperature at 25°C. 15 Example I For each of the Samples provided in Table I, compositions were made for foam assess-ment with surfactant as shown. The surfactants shown were combined with a wash basehaving, 0.3% caprylyl glycol, 0.4% glycol distearate, 0.1% 12-hydroxystearic acid, 0.25% lauric acid, 0.25% stearic acid, 0.1% glycerin, 0.95% preservative, 0.05% chelator, 1% fra- 20 grance and thickener to achieve a viscosity from about 7,400 to 8,100 mPa-s, all based ontotal weight of the surfactant and wash base. The pH of the resulting compositions was 6.8 to 7.1 Foam analysis (in milliliter) was conducted for each Sample, and then averaged.Foam analysis was then repeated for the Samples in Table I and compared to the figures obtained when an average was taken. For clarification, foam analysis was performed with 25 compositions having anionic X (C12 taurate or isethionate), then anionic Y (C18 lactylate)and the measurements were averaged. Compositions were then made with anionic X andY. Compositions made according to the invention, surprisingly, resulted in foam or lathersignificantly higher than the weighted average of the two compositions (base foam) not having the combination of anionics, reported as Foam Assessed. 30 P0000785CPL Foam Analysis Method as performed with Sita Foam Tester R-2000Foam Measurement Parameters: Mixing Speed: 1000 rpm; Measurement time: intervals15 seconds with data reported in Table I at 60 seconds; Dilution: 250mL Sample Size: 5gProcedure / Surfactant Mix. 51) Run cleaning cycles using (22°C) water to ensure vessel is clean, and to equilibratetemperature of vessel. 2) Fill water reservoir with 38°C water.
