Abstract
A cleansing composition comprising (a) a cleansing amount of a surfactant or mixture of surfactants,(b) a skin slip inducing amount of a quaternized lanolin or mixture of quaternized lanolins, and (c) a skin slip enhancing inducing amount of a further cationic material or a mixture of cationic materials.
Description
SKIN CLEANSING COMPOSITION COMPRISING QUATERNIZED LANOLIN
BACKGROUND OF THE INVENTION
Cleansing compositions have been beneficial to mankind for centuries. Basic cleansing has, therefore, been accomplished. Presently, people are desiring an effect beyond that of simple cleansing.
It has now been found that the incorporation of a quaternized lanolin, specifically Quaternium 33 i.e., lanolin amidopropyl dimethyl ether ammonium ethosulfate, preferably with a further quaternary material into a water rinse-of skin cleansing composition brings about an effect easily detectable by people and also enjoyable. This effect, a sensorial skin feel signal (skin slip) observed during and after use of a water rinse-off composition such as in a shower, leaves the skin feeling soft and smooth. The Quaternium 33 is not a classical emollient which are water insoluble but is rather water soluble and its effect is substantially amplified by the addition of other water soluble cationic materials, for example Polyquaternium-7 and a quaternized guar such as guar gum (2-hydroxypropyl-2-hydroxy-3-(trimethylammonium) propyl ether. Softness and smoothness is associated with a moisturizing benefit. Deposition of the material on skin can be detected by a particular test system. In addition, the combination of cationic materials provides the desired aesthetics of a single phase as well as "stand up"
properties of a liquid or gel formulation. The combination can be readily added to the liquid or gel composition in a fragrance without the assistance of further emulsifying agents and at room temperature. Fragrance substantivity on the skin can be enhanced by using the combination of cationic materials.
SUMMARY OF THE INVENTION
In accordance with the invention, there is a cleansing composition comprising, (a) a cleansing amount of a cleansing surfactant or mixture of surfactants, (b) a skin slip inducing amount of a quaternized lanolin or mixture of quaternized lanolins, and (c) a skin slip enhancing inducing amount of at least one further cationic material or a mixture of cationic materials.
In a further embodiment, there is provided the composition as described herein, wherein when the composition is a bar about 5 wt. % of surfactant is present and when the composition is a liquid or gel about 1 wt. % of surfactant is present in the composition.
la DETAILED DESCRIPTION OF THE INVENTION
The cleansing composition can come in any convenient form such as a solid, liquid, gel, spray, aerosol, foam and the like. A cleansing surfactant or mixture of surfactants are employed in the composition to bring about a cleansing effect when applied to the skin and preferably rinsed off with water.
These "rinse off' compositions can be rinsed off the skin in less than about one minute, preferably less than about 45, 30 or 15 seconds after application.
Examples of cleansing surfactants which can be employed in the composition include anionic, nonionic, amphoteric and cationic and any mixture thereof.
Any anionic surfactant can be employed. Examples of such anionic surfactants include soap, a long chain alkyl or alkenyl, branched or normal carboxylic acid salt such as sodium, potassium, ammonium or substituted ammonium salt, can be present in the composition. Exemplary of long chain alkyl or alkenyl are from about 8 to about 22 carbon atoms in length, specifically about 10 to about 20 carbon atoms in length, more specifically alkyl and most specifically normal, or normal with little branching. Small quantities of olefinic bond(s) may be present in the predominantly alkyl sections, particularly if the source of the "alkyl" group is obtained from a natural product such as tallow, coconut oil and the like. Anionic nonsoap surfactants can be exemplified by the alkali metal salts of organic sulfate having in their molecular structure an alkyl radical containing from about 8 to about 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). Preferred are the sodium, ammonium, potassium or triethanolamine alkyl sulfates, especially those obtained by sulfating the higher alcohols (C8-C18 carbon atoms), sodium coconut oil fatty acid monoglyceride sulfates and sulfonates; sodium or potassium salts of sulfuric acid esters of the reaction product of 1 mole of a higher fatty alcohol (e.g., tallow or coconut oil alcohols) and 1 to 12 moles of ethylene oxide; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfate with 1 to 10 units of ethylene oxide per molecule and in which the alkyl radicals contain from 8 to 12 carbon atoms, sodium alkyl glyceryl ether sulfonates; the reaction product of fatty acids having from 10 to 22 carbon atoms esterified with isethionic acid and neutralized with sodium hydroxide; water soluble salts of condensation products of fatty acids with sarcosine; and others known in the art for example taurates and phosphate.

A quaternized lanolin provides the skin sensorial feel that is unique to the composition. Examples are the previously mentioned Quaternium 33, quaternized lanolins with various counterions such as chloro, bromo, nitrate, nmethosulfate, acetate, lactate, and the like, quaternized lanolins wherein an amidoethyl or amido butyl grouping is used rather than an amido propyl as in Quaternium 33 and diethyl or dipropyl ether ammonium grouping is employed rather than the dimethylether ammonium group of the Quaternium 33.
It is preferable to employ at least one further quaternized material in the composition. This brings about accentuation of the skin slip sensorial feel present with the quaternized lanolin or can lower the minimum amount of quaternized lanolin associated with the skin slip. These further quaternized materials can be cationic materials which include the various polyquats known to the art which include but are not limited to Polyquaternium 2 (a po(yelectrolyte formed from quaternized ioenes), Polyquaternium 4 (hydroxycellulose diallyidimethyl ammonium chloride), Polyquaternium 5 (acrylamide/R--methacryloxyethyltrimethyl ammonium methosulfate), Polyquaternium 6 and 7 (homopolymer of dimethyl diallyl ammonium chloride and the copolymer of dimethyl diallyl ammonium chloride with acrylamide), Polyquaternium 8 (methyl and stearyl dimethylaminoethyl methacrylate quaternized with dimethylsuifate), Polyquaternium 10 (1-hydroxyp.ropyi trimethyl ammonium chloride ethers of hydroxyethyl cellulose), Polyquaternium 11 (quaternized PVP and dimethylaminoethyl methacrylate), Polyquaternium 16 (copolymer of PVP/methyl vinylimidazoline), Polyquaternium 17 and 18 (polyelectrolyte formed from quaternized ioenes), Polyquaternium 19 (a vinyl alcohol hydroxypropyl amine salt), Polyquaternium 24 (polymeric quaternized ammonium salt of hydroxymethylcellulose and lauryl dimethyl ammonium substituted epoxide), Polyquaternium 27 (polyelectrolyte formed from quaternized ioenes).

Preferably a quaternized guar for example quaternized quar per se, hydroxyethyl quaternized guar and more preferably guar gum (2-hydroxypropyl-2-hydroxy-3-(trimethylammonium) propyl ether is employed.
A cleansing effective amount of a cleansing surfactant should be employed in the composition. Generally, for liquid or gets, at least about 1 wt. %
of the composition should be a surfactant or a mixture of surfactants.
Desirably, at least about 2, 3. 4, or 5 wt. % should be employed. For liquids or gels, the quantity of surfactants generally is no more than about 30 wt. % of the composition, preferably no more than about 25, 20, 15 or 12 wt. % of the composition. For solids, an even higher minimum can be used as well, for example, preferably about 10, 20, 30. 40 or 50 wt. % of the composition can be surfactant(s). When a solid composition such as a bar is employed, the maximum amount of surfactant(s) is generally no more than about 90 wt. % of the composition, preferably no more than about 85, 80 or 75 wt. % of the composition. With respect to other forms, such as sprays, aerosols, and the like the quantity of surfactant(s) is similar to that of the liquids or gels with respect to the actual cleansing composition, excluding whatever propellant might be present. With respect to water content, for solids at least about 5 wt. %
water is present with generally no more than about 30, 25, 20 or about 15 wt. % water.

With respect to the quaternized lanolin, particularly Quaternium 33, any quantity which brings about detectable "skin slip" can be used. With respect to solids, this can be a wt. % minimum of the composition of about 0.1, preferably 0.2, 0.4 and 0.6. Generally, a maximum of about 3 wt. % of the composition.
preferably no more than about 2, 1.5 or 1.0 wt. % of the composition is employed. A minimum amount of the quaternized lanolin in liquid or gels is generally about 0.1, preferably 0.25 or 0.5 wt. % of the composition. Maximum quantities of the quaternized lanolin is generally no more than 2.5 wt. %, preferably no more than about 1.0 or 0.5 wt.%.
The additional cationic materials present in the composition in quantities which reduce the amount of quaternized lanolin necessary to bring about skin slip or enhance the quantity of skin slip brought about by the quaternized lanolin.
With respect to solids, this can be a wt. % minimum of the composition of about 0.1, preferably 0.2 and 0.4. Generally, a maximum of about 2 wt. % of the composition, preferably no more than about 1.5 or 1 wt. % of the composition is employed.
