Definitions

  • the present invention is related to liquid cleansing products, especially bath/shower compositions which contain a cellulose polymer as a thickening/skin feel aid and a solvent for viscosity control and phase stability.
  • liquid personal cleansing products can be thickened by:
  • the Figure shows four viscosity curves for five products vs. product concentration.
  • Curve 1 represents Example A;
  • Curve 2 represents Example 11;
  • Curve 3 represents Examples 1 (same as Example B) and 111; and
  • Curve 4 Example C The five product formulations are found in the examples.
  • Curve 1 represents a product which has a high degree of slipperiness but is difficult to rinse.
  • Curves 2 and 3 represent products which have the desired degree of slipperiness and ease of rinsing.
  • Curve 4 represents a product which has a low degree of slipperiness, but which is easy to rinse.
  • the present invention relates to liquid cleansing compositions comprising from about 0.1% to about 1.5% of a water-soluble cellulose polymer consisting of hydroxymethyl-, hydroxyethyl-, hydroxypropyl-, hydroxybutyl methyl-, carboxymethyl cellulose, and the like, from about 0.5% to about 20% of a solvent consisting of ethylene glycol or propylene glycol (the monomers) or polyoxyethylene glycol or polyoxypropylene glycol (considered as polymeric forms of ethylene glycol and propylene glycol, respectively) or the mixed block copolymers of polyoxyethylene glycol and polyoxypropylene glycol and mixtures thereof, from about 10% to about 50% of a synthetic surfactant, and from about 50% to about 80% of water.
  • the liquid cleansing composition has a neat (100%) viscosity of 2,000-12,000 cps and a dilute (50%) viscosity of 15-95 cps.
  • the compositions must contain less then 1% electrolyte.
  • An important attribute of a personal cleansing product is the feel of the product in use. This feel can be described as soft, silky and slippery. Another important attribute is the ease of rinsing of the product while in use. A poor rinsing product can be described as one in which there is a prolonged feeling of slipperiness and slickness during the rinsing process.
  • the slipperiness and ease of rinsing of a product can be related in part to the viscosity of the solution of the product in water as it is diluted. This can be used to help describe products which have the desired level of skin feel and ease of rinsing characteristics for certain end uses.
  • the desired product must then be formulated to provide the desired dilute viscosity curve which controls skin feel and rinsing in use, the desired neat viscosity, the desired amount of lather in use and a stable product that does not separate or change in neat viscosity while stored.
  • This invention relates to shelf stable products with desirable neat viscosity, using selected thickeners, e.g., hydroxyethyl cellulose, and selected solvents, e.g., polyoxyethylene or propylene glycol.
  • selected thickeners e.g., hydroxyethyl cellulose
  • selected solvents e.g., polyoxyethylene or propylene glycol.
  • the cellulosic thickeners in this invention are categorized as nonionic or anionic and are selected to provide the desired viscosities. Suitable cellulosic thickeners are listed in the Glossary and Chapters 3, 4, 12 and 13 of the Handbook of Water-Soluble Gums and Resins, Robert L. Davidson, McGraw-Hill Book Co., New York, N.Y., 1980, incorporated by reference herein.
  • the nonionic cellulosic thickeners include, but are not limited to, the following polymers:
  • the anionic cellulosic thickener includes carboxymethyl cellulose and the like.
  • the preferred thickener is hydroxyethyl cellulose, which is made by treating cellulose with sodium hydroxide and reacting with ethylene oxide. Hydroxyethyl groups (molar substitution 1.5 to 3, preferably 2 to 3) are introduced to yield a hydroxyethyl ether. The reaction product is purified and ground to a fine white powder.
  • the amount of cellulosic thickener found useful in the present compositions is about 0.1% to about 1.5%, preferably from about 0.1% to about 1.0%.
  • the thickeners are used in combination with the solvent to produce the neat and dilute viscosities of 2,000 to 12,000 cps and 15 to 95 cps, respectively, preferably 4,000 to 10,000 cps and 20 to 60 cps, respectively.
  • a second essential component of the present compositions is solvent consisting of ethylene glycol or propylene glycol (the monomers) or polyoxyethylene glycol or polyoxypropylene glycol (considered as a polymeric form of ethylene glycol or propylene glycol) or the mixed block copolymers of polyoxyethylene glycol and polyoxypropylene glycol and mixtures thereof.
  • the polymeric forms of solvent have an average molecular weight in the range of from about 200 to about 10,000, preferably 400 to 800.
  • the solvent is present at a level of from about 0.5% to about 20%, preferably from about 1% to about 10% in the present compositions.
  • the third essential component of the present compositions is a surfactant.
  • the surfactant which may be selected from any of a wide variety of anionic (nonsoap), amphoteric, zwitterionic, nonionic and, in certain instances, cationic surfactants, is present at a level of from about 10% to about 50%, preferably from about 10% to about 30%.
  • Anionic nonsoap surfactants can be exemplified by the alkali metal salts of organic sulfuric reaction products having in their molecular structure an alkyl radical containing from 8 to 22 carbon atoms and a sulfonic acid or sulfuric acid ester radical (included in the term alkyl is the alkyl portion of higher acyl radicals).
  • Nonionic surfactants can be broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound, which may be aliphatic or alkyl aromatic in nature. Examples of preferred classes of nonionic surfactants are:
  • Zwitterionic surfactants can be exemplified by those which can be broadly described as derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, in which the aliphatic radicals can be straight chain or branched and wherein one of the aliphatic substituents contains from about 8 to 18 carbon atoms and one contains an anionic water-solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.

  • R contains an alkyl, alkenyl, or hydroxy alkyl radical of from about 8 to about 18 carbon atoms, from 0 to about 10 ethylene oxide moieties and from 0 to 1 glyceryl moiety;
  • Y is selected from the group consisting of nitrogen, phosphorus, and sulfur atoms;
  • R 3 is an alkyl or monohydroxyalkyl group containing 1 to about 3 carbon atoms;
  • X is 1 when Y is a sulfur atom and 2 when Y is a nitrogen or phosphorus atom;
  • R 4 is an alkylene or hydroxyalkylene of from 1 to about 4 carbon atoms and Z is a radical selected from the group consisting of carboxylate, sulfonate, sulfate, phosphonate, and phosphate groups.
  • Examples include: 4-[N,N-di(2-hydroxyethyl)-N-octadecyl- ammonio]-butane-1-carboxylate; 5-[S-3-hydroxypropyl-S-hexade- cylsulfonio]-3-hydroxypentane-1-sulfate; 3-[P,P-P-diethyl-P-3,6, 9-trioxatetradexocylphosphonio]-2-hydroxypropane-1-phosphate; 3- [N,N-dipropyl-N-3-dodecoxy-2-hydroxypropylammonio]-propane-1-phosphonate; 3- (N, N-dimethyl-N-hexadecylammonio)propane-1-sulfonate; 3-(N,N-dimethyl-N-hexadecylammonio)-2-hydroxypropane-1-sulfonate; 4-[N,N-di(2-
  • amphoteric surfactants which can be used in the compositions of the present invention are those which can be broadly described as derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical can be straight chain or branched and wherein one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.

  • Pre-Wash Panelists were asked to first wash both forearms using CAMAY toilet bar soap. After rinsing, while the arms were still wet, an initial skin friction reading (using a Skin Friction Meter, Ser. No. 595108, made by the Department of Engineering, University of Newcastle, Newcastle, England) was made on both forearms. Two syringes were then filled with 1.0 ml of two of the three products to be tested.
  • Skin friction data of product on skin correlate with expected in-use slipperiness based on the skin feel agents used in the following products. Examples A, B and C listed below describe the three formulas used in this test.
  • a full product formula was made with 0.2% hydroxyethyl cellulose (HEC) and 3% propylene glycol.
