Claims19
A solid cosmetic composition comprising:
- a surfactant in an amount of about 50% to less than about 95% by weight;
- a hair modification active in an amount of 0.05 to 15 weight %;
- wherein the hair modification active is selected from the group consisting of glycerol monothioglycolate, N-acetyl-L-Cysteine, cysteamine, potassium thioglycolate and a Bowmann-Birk Inhibitor;
- less than 5 weight % water;
- a skin enhancing agent;
- and
- a silicone present in an amount greater than 5% by weight of the solid composition, wherein the pH of the solid cosmetic composition is between 4 and 8.

A solid soap bar capable of repeated use, the solid soap bar comprising:
- surfactant in an amount of about 40% to less than about 95% by weight of the solid soap bar;
- a hair modification active;
- wherein the hair modification active is selected from the group consisting of glycerol monothioglycolate, N-acetyl-L-Cysteine, cysteamine, potassium thioglycolate and a Bowmann-Birk Inhibitor;
- and
- a silicone present in an amount greater than 5% by weight of the solid soap bar to increase the hardness and durability of the solid soap bar in comparison to a composition comprising the silicone present in an amount of 5% or less by weight, wherein the silicone is selected from the group consisting of C30-45 Alkyl Methicone and C30-45 Olefin, divinyldimethicone/Dimethicone copolymer and C12-13 Pareth-23 and C12-13 Pareth, stearoyl dimethicone, Lauryl PET/PPG-18/18 Methicone, divinyldimethicone/dimethicone copolymer in emulsion form, declopentasiloxane, B 15-PEG, and methyl ether dimethyl silane, so that the solid soap bar is capable of repeated use,
- wherein the pH of the solid soap bar is between 4 and 8.
