Abstract RU 2827441 C2

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a shampoo composition. Aqueous shampoo composition contains (a) a pre-formed emulsified silicone; (b) 0.05–2 wt.% cationic precipitating polymer - cationic polygalactomannan, having an average charge density at pH 7 of 0.2–2 meq/g; (c) 0.05–5 wt.% of a cationic conditioning polymer having an affinity for hair, - polymer APTAC, having molecular weight less than 1 million daltons and charge density at pH 7 4–6; (d) 3 - less than 12 wt.% detergent surfactant, which has an average degree of ethoxylation En, where the number n denotes the average degree of ethoxylation and is in range of 0–3; (e) auxiliary surfactant (co-surfactant), which is a betaine surfactant selected from amidobetaine amphoteric surfactant and alkylbetaine; (f) a suspending agent, wherein the weight ratio of (g) to (e) is in range of 1:1–4.5:1, the pH of composition is 3–6.5. Also disclosed is a method of treating hair and using a cationic conditioning polymer in a shampoo to retain silicone on hair.

EFFECT: group of inventions provides deposition and retention of silicone on hair.
