Embodiment Construction

[0013] The liquid cleansing compositions herein contain water, surfactants, hydrophobic skin care actives and certain water-insoluble oils, which are further described below.

[0014] As used herein, the term "rinsing feel" refers to the sensation on the skin during lather removal from the skin after rinsing with a cleansing composition. The type of cleansing feel produced by the compositions of the invention can be described by terms such as "astringent" cleansing, "soapy" cleansing and "non-slippery" or "non-slimy" cleansing. This "astringent", "soapy", "non-slippery" or "non-sticky" cleansing feel can be perceived by increased friction between the hand and the skin during cleansing of the lather on the skin.

[0015] As used herein, the term "water-insoluble" (oil) refers to a substance that is substantially insoluble in distilled water at room temperature without the addition of other adjuvants and / or ingredients such as those described herein.

[0016] As used herein, th...

Abstract

A rinse-off liquid personal cleansing composition comprising (a) water; (b) from about 1% to about 60% by weight of a water-soluble surfactant, (c) a water-insoluble oil selected from highly branched polyalphaolefins having formula (1): wherein R<1> is H or C1-C20 alkyl, R<4> is C1-C20 alkyl, R<2> is H or C1-C20, and R<3> is C3-C20 preferably from C5-C20, n is an integer from 0 to 3 and m is an integer of from 1 to about 1000 and having a number average molecular weight of from about 1000 to about 25,000; and (d) a hydrophobic skin active component selected from antimicrobial agents, sunscreens, vitamins, perfume oils insect repellants, anti-fungal agents, and mixtures thereof, wherein the hydrophobic skin active component has a ClogP value of greater than 3. The personal cleansing compositions of the invention provide improved deposition of hydrophobic skin actives, excellent rinse feel and skin mildness.

Description

technical field [0001] The present invention relates to cleaning compositions. In particular, the present invention relates to mild personal cleansing compositions which exhibit improved deposition of skin care actives such as antimicrobials, sunscreens and vitamins. Furthermore, the compositions according to the invention exhibit improved cleansing and good skin contact as well as foaming properties. They are suitable for simultaneously cleansing and conditioning the skin and / or hair, e.g. foaming bath products, shower products, skin cleansers , hand, face and body cleanser, shampoo and more. Background of the invention [0002] Mild cosmetic compositions have to meet several criteria including cleansing power, foaming and mildness / low irritation / good skin, hair and ocular mucous membrane feel. Skin is made up of several layers of cells that cover and protect the underlying tissue. Keratin and collagen fibril proteins form its structural backbone. T...
