摘要：
A composition containing sulfonated keratin with molecular weight distribution of about 96.8% 100 kDa to 100 Da and about 3.2% 250 kDa to 100 kDa, at least one cationic surfactant, and optionally an aqueous carrier. Generally the keratin is produced by a method involving treating wool with about 0.5 to about 1.0N NaOH in a bath volume:wool weight of about 5:1 to about 10:1 at about 40° C. to about 65° C. for about 4 to about 8 hours with dosing about every 1 to 3 hours with about 1% to about 10% by weight of bath of hydrogen peroxide. Also a method for treating a keratin based substrate involving contacting or applying the substrate (e.g., hair) with the composition.
