Description

Personal cleansing composition

Technical Field

The present invention relates to body care compositions in the form of oil-in-water emulsions useful for cleaning skin and hair. These emulsions are stable during storage and demulsified upon skin contact to release the oil phase for conditioning and hydration. Such compositions have the advantage of maintaining skin and providing enhanced cleansing efficacy without irritating the skin or leaving the skin pulling or tingling.

Background of the Invention

The body protection industry has long dealt with the basic skin cleansing action. Removing dirt from the skin is a requirement of global consumers that commercial skin cleansing products must meet. In the cleaning process, the surfactant removes the natural lipids of the skin to keep the skin supple, moisturize the skin and protect the skin from the rain. Frequent use of cleansing products can damage the skin (ie, dry and sting), causing discomfort and possible skin problems.

In this field, much research and efforts have been extended to prepare cleaning compositions that not only clean skin efficiently but also condition skin.

Several patents and publications describe the use of dimer acids.

Japanese Unexamined Patent Publication (Shiseiido) includes dimer acid, stearic acid, cetanol, petrolatum, squalene, glycerin monostearate, monosodium-N-stearoylglutamate, propylene glycol, potassium hydroxide and carboxyvinyl polymer It has been reported that oil-in-water emulsions are described.

WO 94/20067 (PCT / EP94 / 00814) describes emulsions consisting of dicarboxylic acids and emulsifiers selected such that the emulsion can shear thicken in use. According to the said patent document, these emulsions can be used for toiletries, cosmetics compositions, and pharmaceutical compositions.

The following patents and publications describe the use of polyisobutylene, polymeric isobutylene and polyisobutene, also called polymeric isobutene.

U. S. Patent No. 5,658, 577 to Fowler describes abrasion resistant thickened aqueous body cleansing compositions using ultra finely divided insoluble cleaning particles. One of the materials identified in its general description regarding solid cleaning particles is polyisobutylene.

WO 96/32092 (PCT / US96 / 05038) describes compositions for body cleansing in the form of oil-in-water emulsions which have properties that degrade upon skin contact. The composition contains (1) a specific copolymer, (2) a non-emulsifiable cleaning surfactant, (3) an oil selected from the group of specific compounds, and (4) water. Two of the many identified oils are hydrogenated polyisobutylene and isohexanedecane [according to this publication, it is reported that Presperse, Inc., South Plainfield, NJ, is using Permethyl. A commercially available hydrocarbon product under the trade name 101A].

WO 97/16168 (PCT / US96 / 17506) describes body cleansing compositions containing (1) surfactants, (2) hydrophobic active ingredients, (3) hydrocarbon-containing components, and (4) cationic polymers. . The hydrocarbon-containing component may be a “permethyl” of formula CH ₃ — (— C (CH ₃ ) ₂ —CH ₂ —) _n —C (CH ₃ ) H—CH ₃ , where n may vary from about 4 to about 200 May be). Products where n is 4, 16, 38, and 214, respectively, are described as commercially available under the trade names Permethyl 102A, 104A, 106A, and 1082A in Presspers. In the examples of this document, permenyl 104A and 106A are used.

U.S. Patent 5,441,730 describes shampoos, rather than hand cleaners, which contain polymeric isobutylene and surfactants (not including cationic surfactants). The reference also describes hair styling compositions containing cationic surfactants as conditioning components.

Skin cleansing compositions must satisfy a number of criteria acceptable to the consumer. These criteria include hydration and conditioning as well as ease of cleansing, applying and rinsing, rich foam, good skin feel during and after use and hypoallergenic to the skin. The ideal skin cleanser should be able to provide these product characteristics even when used frequently.

In an average home environment, the frequency of hand washing is about 5 to 10 times per day. These consumers are the average consumer who buys skin cleaners at the local supermarket. Most of the high quality skin cleansers on the market meet these consumer needs.

Such skin cleansers use a surfactant formulation that provides foaming properties with minimal irritation. The conditioning cleanser composition includes a emollient and moisturizer that gives the skin a coated feel after rinsing. Application feel is often the result of using triglyceride oils to provide the conditioning desired by the consumer; However, most consumers want conditioning benefits that are difficult to rinse and give no application feel.

Another part of the market is professional caregivers who need to wash their hands about 30 to 50 times a day to minimize cross contamination and consequent pathogenic infections. These consumers need skin cleaners that do not damage the skin even if used at high frequency. They also have no time or, in some cases, cannot apply hand lotion every hand wash. Another product feature that they pursue is that they must be easy to rinse off the product because they frequently have to rush from patient to patient.

Thus, (a) a body cleansing composition that can be used at least 30 times a day without irritating or drying the skin, (b) easy to rinse off, and (c) leaving a clean, conditioned texture on the skin. This is still required.

The gist of the invention

The body cleansing compositions of the present invention provide long-term, lasting skin conditioning and hydrating benefits to maintain skin even under conditions of frequent use, have cosmetic-like elegance and provide effective cleaning properties.

The body cleansing composition according to the present invention

(a) at least one polymeric isobutene having from about 12 to about 156 carbon atoms, preferably from about 24 to about 156 carbon atoms, which is liquid at room temperature and at atmospheric pressure,

(b) one or more formulas Of dicarboxylic acids, wherein R 1 and R 3 are each C ₆ -C ₁₀ alkyl and R 2 and R 4 are each C ₆ -C ₁₀ alkylene, or a cosmetically acceptable salt thereof,

(c) at least one surfactant selected from the group consisting of anionic surfactants, amphoteric surfactants, nonionic surfactants, zwitterionic surfactants and combinations thereof; and

(d) contains water.

Polymeric polyisobutenes and dicarboxylic acids are hydrophobic and present directly on the skin. These two substances remain on the skin even when cleansed, providing long-term continuous conditioning and hydration to the skin.

The polymeric isobutene component of the compositions of the present invention deposits a hydrophobic membrane on the skin to provide long term sustainable skin conditioning. Liquid polymeric isobutene is mainly used in cosmetic formulations and not in body cleansing compositions. Polymeric isobutene can be hydrogenated. The polymeric isobutene is preferably present in an amount of about 0.1 to about 10 weight percent, more preferably about 1 to about 8 weight percent, based on the total weight of the composition.

The dicarboxylic acid is preferably a dimer acid in which R 1 and R 3 are the same alkyl and R 2 and R 4 are the same group. The dicarboxylic acid is preferably present in an amount of about 0.1 to about 10 weight percent, more preferably about 1 to about 8 weight percent.

The surfactant is preferably present in an amount of at least 1% by weight, more preferably from about 2% to about 30% by weight, most preferably from about 5% to about 25% by weight, based on the weight of the composition. The surfactant component provides a flashy, rich foam that is difficult to obtain in compositions rich in hydrophobic skin conditioning components. The surfactant is preferably gentle to the skin and provides a foaming ability flashed into the composition. Provides foam rich in anionic surfactants. Amphoteric surfactants and zwitterionic surfactants provide foam stability and a mild feel and also increase viscosity. Nonionic surfactants provide a clean and mild feel and also provide viscosity.

The compositions of the present invention may optionally further comprise viscosity increasing agents and / or emulsifiers such that the viscosity raising and emulsifying properties are not provided or insufficiently provided by the polymeric isobutene, dicarboxylic acid and surfactant (s). have.

If emulsifiers are present, these emulsifiers are preferably present in amounts of about 0.1 to 5 weight percent, more preferably about 0.1 to about 2.5 weight percent.

If a viscosity increasing agent is present, these viscosity increasing agents are preferably present in an amount of about 0.1 to about 5 weight percent, more preferably about 0.1 to about 2.5 weight percent.

Polyglycerol esters have both the properties of viscosity enhancers and emulsifiers. Polyglycerol esters have the added advantage of being present directly on the skin to provide long term hydration. If a large amount of hydrophobic component is present in the composition, the surfactant alone is usually not suitable for keeping the composition homogeneous. Therefore, it is desirable to use polyglycerol esters to increase the viscosity, to emulsify and to keep the composition homogeneous. If polyglycerol esters are present, these polyglycerol esters are preferably present in an amount of about 0.1 to about 5 weight percent, more preferably about 0.1 to about 2.5 weight percent.

The compositions of the present invention optionally further comprise one or more amine functional silicones, preferably in an amount of about 0.1 to about 3 weight percent, more preferably about 0.1 to about 2 weight percent. These ingredients provide significant skin conditioning and reduce or inhibit the sticky feeling applied by the polymeric isobutene and dicarboxylic acids used in the composition.

Both polyglycerol esters and amino functional silicones may be present in the composition. However, amino functional silicones can be used without polyglycerol esters if the surfactants in the composition (eg, amphoteric and nonionic surfactants can act as viscosity increasing agents) provide sufficient viscosity to the composition.

The composition of the present invention may further comprise polyethyleneglycol having a molecular weight of about 1,500,000 to about 5,000,000 in an amount of preferably about 0.01 to about 0.7% by weight, more preferably about 0.05 to about 0.4% by weight. These ingredients provide a smooth feel during use. These components act as lubricants or slip agents.

Unless stated otherwise, all percentages used herein are percentages by weight of the total composition and all measurements are performed at 25 ° C. Unless stated otherwise, all weight percentages are based on the weight of the active ingredient (as opposed to the weight percentage of commercially available materials containing the active ingredient in the solvent).

Formulations 1462-151 and 1462-161 are formulated to provide a smooth feel while applying the product to the hand. Polyethylene glycols provide this quality. In this example, PEG-90M is used.

The 25-person sensory panel uses these two formulations and the standard product (the panel hides its identity). Each panel washes hands at least three times a day (typically in household) with each formulation, ranking each formulation on a scale of 0 to 7, where 7 is the best panel for any particular property. Satisfaction is shown, with 0 representing the highest satisfaction in the "coating feel" category. The results are shown in Table 3.

One of the desired performances of the present invention is to provide a skin cleanser having a long term conditioning effect, including moisture supply properties. Categories marked with a "*" are related to the desired performance. The application feel category was included because it provides an indication of user acceptance.

The results evaluated by the sensory panel showed that Formulations 1462-151 showed better moisture supply properties but slightly less foaming compared to the standard formulation [Oil of Olay Moisturizing Body Wash]. Overall preferences and preferences were equivalent. The panel was asked to choose the best of the three, with 40% choosing formulations 1462-151 and 48% choosing standard formulations.

Formulations 1462-161 are prepared and used in a state in which the functional panel is not initially evaluated for basic properties such as viscosity before use. Formulations 1462-161 were not recognized to perform as well as formulations 1462-151 and standard formulations. This is partly due to the higher viscosity than the other two formulations tested. Due to the higher viscosity, panels were more difficult to remove the product from the container. This has a negative halo effect on the performance of the formulation. The increase in viscosity is believed to be due to the use of disodium laureth sulfosuccinate (which is not used in formulations 1462-151) and the interaction of these components with other ingredients that can form micelles. Lowering the concentration of these components to, for example, about 1.5% by weight (the amount of disodium cocoglucoside citrate used in Formulations 1462-151) will reduce this high viscosity and result in a less viscous product. I think.

One of the desired performances of the present invention is to provide a skin cleanser that can be used at least 30 times a day without causing skin irritation or dryness. The formulation was tested by a professional by washing 30 times per day with Formulations 1462-151 for 1 week. Digital imaging was used to demonstrate the effect of the skin cleanser on the hands. Before use, digital photographs were taken on days 2, 4 and 7 of use. The photographs showed no visible skin irritation or dryness even after 7 days of frequent hand washing.
