Description
-I-FOAMABLE SKIN PREPARATIONS
BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to foamable skin preparations suitable for use as shaving preparations and body washes. More particularly it relates to formulations which contain a surfactant, a fatty ester of polyethylene glycol, and a cellulosic ether.
Related B~ckeround Art A wide variety of shaving creams, gels, and lotions are known. ee e_.~
U.S. patent 5,45l,396. The disclosure of this patent and of a11 other publications referred to herein are incorporated by reference as if fully set forth herein.
Also, a wide variety of personal cleansing compositions are known. , ee g.,g,, U.S.
patent 5,534,265.
However, it is desirable for a single product to be useful as both a body cleanser and a shaving preparation, particularly for use by women who wish to 2 0 shave their legs when showering. Standard soaps and body washes have good rinsability and are easy to apply over a wide area. However, a shaving preparation should preferably be designed for more localized application and provide blade protection.
Foamability is also important in that it permits tracking of where shaving 2 5 has taken place, and also contributes to a consumer's perception that a product is likely to be protective. Standard body soaps often have poor foamability.
Fatty esters of polyethylene glycol are known to provide blade protection.
They also contribute to good skin conditioning. However, they can inhibit foaming.
BACKGROUND OF THE INVENTION

patent 5,534,265.
However, it is desirable for a single product to be useful as both a body cleanser and a shaving preparation, particularly for use by women who wish to 2 0 shave their legs when showering. Standard soaps and body washes have good rinsability and are easy to apply over a wide area. However, a shaving preparation should preferably be designed for more localized application and provide blade protection.
Foamability is also important in that it permits tracking of where shaving 2 5 has taken place, and also contributes to a consumer's perception that a product is likely to be protective. Standard body soaps often have poor foamability.
Fatty esters of polyethylene glycol are known to provide blade protection.
They also contribute to good skin conditioning. However, they can inhibit foaming.
3 0 Thus, a need exists for an improved foamable skin preparation which can be used both for body wash and shaving preparation purposes _2_ Brief Summary of the Invention In one aspect the invention provides a skin preparation which contains .5% to 50% by weight of an amphoteric surfactant, .O1 % to 2% by weight of a cellulosic ether, and .0l % to 5% by weight of an ester of polyethylene glycol.
Detailed Description of the Invention In a preferred form the ester is a C 12 to C22 fatty ester (e.g. polyethylene glycol-8-distearate), the amphoteric surfactant is selected from the group consisting of betaine and sultaine, and the cellulosic ether is an alkyl hydroxyalkyl cellulose ether such as cetyl hydroxyethyl cellulose (sold under the trade name Natrosol~ CS Plus from Aqualon Corporation). The formulation may also include preservatives, colorants, other surfactants, fragrances, vitamins, emollients, pigments, foam stabilizers, and humectants.
In another aspect the invention provides methods of shaving human skin.
They involve applying the skin preparation of the present invention to the skin, rubbing the skin preparation until foam is formed, and then shaving the skin with a razor.
The most preferred amphoteric surfactants are betaines and sultaines, such 2 0 as lauramidopropyl betaine. However, a wide variety of other amphoteric (and other surfactants) can also be included, such as sodium Iauroyl sarcosinate.
Further examples of amphoteric surfactants which can be used are derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical can be straight or branched chain and wherein one of the aliphatic 2 5 substituents contains from about 8 to about 22 carbon atoms (preferably C8-C ~ g).
Examples are alkyl imino acetates, and iminodialkanoates and aminoalkanoates of the formulas RN[(CH2)mC02M]2 and RNH(CH2),~COZM wherein m is from 1 to 4, R is a Cg-C22 alkyl or alkenyl, and M is H, alkali metal, alkaline earth metal, ammonium, or alkanolammonium. Also included are imidazolinium and 3 0 ammonium derivates.
Specific examples of other suitable amphoteric surfactants include sodium 3-dodecyl-aminopropionate, sodium 3-dodecylaminopropane sulfonate, N-alkyl-taurines, N-higher alkyl aspartic acids, and the products sold under the trade name "Miranol". Other examples of useful amphoterics include phosphates, such as cocamidopropyl PG-dimonium chloride phosphate (commercial available as Monaquat PTC, from Mona Corp.).
Other examples of suitable betaines include the higher alkyl betaines, such as coco dimethyl carboxymethyl betaine, lauryl dimethyl carboxymethyl betaine, lauryl dimethyl alphacarboxyethyl betaine, cetyl dimethyl carboxymethyl betaine, cetyl dimethyl betaine (available as Lonzaine 16SP from Lonza Corp.), lauryl bis-(2-hydroxyethyl)carboxymethyl betaine, stearyl bis-(2-hydroxyethyl) carboxy-methyl betaine, oleyl dimethyl gamma-carboxypropyl betaine, lauryl bis-(2-hydroxypropyl)alphacarboxyethyl betaine, coco dimethyl sulfopropyl betaine, stearyl dimethyl sulfopropyl betaine, lauryl dimethyl sulfoethyl betaine, lauryl bis-(2-hydroxyethyi) sulfopropyl betaine, and amidobetaines and amidosulfo-betaines (wherein the RCONH(CH2)3 radical is attached to the nitrogen atom of the betaine), oleyl betaine (available as amphoteric Velvetex OLB-50 from Henkel), and cocamidopropyl betaine (available as Velvetex BK-35 and BA-35 from Henkel).
2 0 Suitable sultaines (including the hydroxysultaines) include cocamido-propyl hydroxysultaine (available as Mirataine CBS from Rhone-Poulenc), and alkylsultaines, alkylamidopropyl hydroxy sultaines, and alkyl hydroxy sultaines.
Examples are cocosultaine, lauryl sultaine, cocohydroxy sultaine, erucamido-pyropylhydroxy sultaine, laurylhydroxy sultaine, oleamidopropylhydroxy 2 5 sultaine, and tallowamidopropylhydroxy sultaine.
Also useful are the alkanoyl sarcosinates corresponding to the formula RCON(CH3)CH~CHzCO~M wherein R is alkyl or alkenyl of about 10 to about 20 carbon atoms, and M is a water-soluble canon such as ammonium, sodium, WO 98l20854 PCT/US97/20221 potassium and trialkanolamine (e.g. triethanolamine), a preferred example of which is sodium lauroyl sarcosinate.
Other surfactants that can be included are sodium cetearyl sulfate, sodium lauryl sulfate, sodium lauryl sarcosinate, sodium cocoyl isethionate, coamidopropyl betaine, sodium laureth sulfate, ammonium laureth sulfate, lauramphodiacetate, cetyl dimethyl betaine, ammonium lauryl sulfate, sodium tallow soap, sodium coconut soap, ceteth-10, steareth-21, steareth-2, ceteth-2, glyceryl stearate, glucose amides, dilauryl dimethyl ammonium chloride, disteryl dimethyl ammonium chloride, dimyristyl dimethyl ammonium chloride, dipalmityl dimethyl ammonium chloride, and mixtures thereof.
A wide variety of hydroxyalkyl cellulose ethers (preferably alkyl hydroxyalkyl cellulose ethers) should also be suitable. These include, without limitation, carboxymethyl hydroxyethyl cellulose, hydroxyethyl cellulose, hydroxyethyl ethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, and methyl hydroxyethyl cellulose. Most preferred among alkyl hydroxyalkyl cellulose ethers is a material given the CTFA designation cetyl hydroxyethyl cellulose which is the ether of cetyl alcohol and hydroxyethyl cellulose. The material is sold under the trade name Natrosol~ CS Plus.
The preferred C,2-C22 fatty ester of polyethylene glycol is polyethylene 2 0 glycol 8 distearate "PEG-8 distearate" . Other potential polyethylene glycol ethers are PEG-2 stearate, PEG-4 stearate, PEG-6 stearate, PEG-8 stearate, PEG-10 stearate, PEG-12 stearate, and PEG-n distearate, where n = 2 to 175, and other PEG-n-stearates where n = 2 to 150.
Notwithstanding the normal tendency of fatty esters of polyethylene 2 5 glycol to suppress foamability of surfactants, in the formulations of the present invention the preparations have very good flash foamability while retaining good blade protection and skin feel. Further, amphoterics are efficient cleaners with good rinsability. The viscosity control provided by the cellulosic ethers helps the shaving foam stay in place in a shower environment.
Detailed Description of the Invention In a preferred form the ester is a C 12 to C22 fatty ester (e.g. polyethylene glycol-8-distearate), the amphoteric surfactant is selected from the group consisting of betaine and sultaine, and the cellulosic ether is an alkyl hydroxyalkyl cellulose ether such as cetyl hydroxyethyl cellulose (sold under the trade name Natrosol~ CS Plus from Aqualon Corporation).
