Abstract
Abstract A rinse-off skin conditioning composition employs a hydrocarbon oil, a di-block or tri-block copolymer as a viscosity improver, optionally a fatty acid ester as an emollient, and a surfactant soluble in the mixture of the hydrocarbon oil, copolymer and fatty acid ester, and capable of dispersing said composition in water. The composition may be applied when showering and then rinsed away, leaving a residue of approximately 3-25 percent by weight of the total applied after rinsing. The residue has a skin-conditioning effect.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A rinse-off skin-conditioning composition for application to human skin while showering, comprising: a) 49-87 percent by weight of the total composition of a mineral oil, b) 0.5-5 percent by weight of the total composition of a mixture of di-block copolymers and tri-block copolymers, wherein said copolymers are comprised of (A) styrene and (B) at least one monomer selected from the group consisting of isoprene and butadiene, c) 0-40 percent by weight of the total composition of a fatty acid ester emollient, and d) 3-4 percent by weight of a non-ionic surfactant soluble in the combination of a, b and c and effective in dispersing the composition into water such that upon rinsing said composition from said skin, approximately 3-25 percent by weight of the composition remains on the skin as residue wherein said non-ionic surfactant is selected from the group consisting of Laureth-3, Laureth-4, Oleth-3, Isosteareth-2, Trideceth-3, C9-11 Pareth-3, C9-11 Pareth-6, C11-15 Pareth-3, C11-15 pareth-5 and mixtures thereof.
Claim 2
Dependent Claim
158 words
A rinse-off skin-conditioning composition for application to human skin while showering, comprising: a) 49-87 percent by weight of the total composition of a mineral oil, b) 0.5-5 percent by weight of the total composition of a mixture of di-block copolymers and tri-block copolymers, wherein said copolymers are comprised of (A) styrene and (B) at least one monomer selected from the group consisting of isoprene and butadiene, c) 0-40 percent by weight of the total composition of a fatty acid ester emollient, and d) 3-4 percent by weight of a non-ionic surfactant soluble in the combination of a, b and c and effective in dispersing the composition into water such that upon rinsing said composition from said skin, approximately 3-25 percent by weight of the composition remains on the skin as residue wherein said non-ionic surfactant is selected from the group consisting of Laureth-3, Laureth-4, Oleth-3, Isosteareth-2, Trideceth-3, C9-11 Pareth-3, C9-11 Pareth-6, C11-15 Pareth-3, C11-15 pareth-5 and mixtures thereof.
Claim 3
Dependent Claim
36 words
The composition of claim 1, wherein said surfactant is selected such that when said composition is mixed with an amount of water equal or greater than the composition and shaken, a white, milky emulsion is produced.
Claim 4
Dependent Claim
47 words
The composition of claim 1, wherein said ester is a fatty acid ester of a monohydric alcohol, a fatty acid ester of an ethoxylated monohydric alcohol, a di- or tri-fatty acid ester of a monohydric alcohol, a fatty acid ester of a polyhydric alcohol and mixtures thereof.
Claim 5
Dependent Claim
25 words
The composition of claim 1, wherein said composition further comprises at least one additive selected from the group consisting of fragrances, preservatives, colorants, and antibiotics.
Claim 6
Dependent Claim
73 words
A method of applying a skin-conditioning composition to human skin in a method to effect skin conditioning, comprising: 1) applying the composition of claim 1 to an individual's skin while showering, 2) rinsing said composition from said individual's skin in the process of showering, and 3) completing showering, such that, upon completion of showering, approximately 3-25 percent by weight of the composition applied remains on the individual's skin as a residue after showering.
