Abstract
The present invention is directed to a composition comprising a combination of surfactants for cleansing keratin fibers, a method for cleansing, use of the composition for cleansing, and kit-of-parts thereof. It has been found that the combination of two anionic surfactants, an amphoteric surfactant, and a diol compound provide a rich foam and superior color retention on pre-colored hair.
Claims19
An aqueous cleansing composition for keratin fibers, comprising surfactants at a total concentration in a range of 8% to 19% by weight, calculated to the total of the aqueous composition, wherein the aqueous composition comprises the following surfactants
- a) a first anionic surfactant selected from cocoyl sarcosinate and its salts, lauroyl sarcosinate and its salts, myristoyl sarcosinate and its salts, stearoyl sarcosinate and its salts, oleoyl sarcosinate and its salts, and palmitoyl sarcosinate and its salts, wherein the salts are formable with cations selected from sodium, potassium, magnesium, and ammonium ions;
- b) a second anionic surfactant selected from laureth sulfate, coceth sulfate, pareth sulfate, capryleth sulphate, myreth sulfate, oleth sulfate, deceth sulfate, trideceth sulfate, coco sulphate, C10-C16 alkyl sulphate, C11-C15 alkyl sulphate, C12-C18 alkyl sulphate, C12-C15 alkyl sulphate, C12-C16 alkyl sulphate, C12-C13 alkyl sulfate, lauryl sulphate, myrystyl sulphate, palm kernel sulphate, cetearyl sulfate, cetyl sulphate, decyl sulphate, oleyl sulphate, behenyl sulphate, and their salts;
- c) an amphoteric surfactant that is a hydroxysultain surfactant selected from cocoamidopropyl hydroxysultaine, laurylamidopropyl hydroxysultaine, erucamidopropyl hydroxysultaine, lauryl hydroxysultaine, and cocoyl hydrodroxysultaine;
- d) a compound selected from propyl glycerine, butyl glycerine, pentyl glycerine, hexyl glycerine, heptyl glycerine, octyl glycerine, nonyl glycerine, decyl glycerine, undecyl glycerine, dodecyl glycrin, ethylhexyl glycerine;
- and
- e) at least one aminated silicone in the form of the microemulsion having droplet sizes in the range of 50 nm to 1000 nm,
- wherein the aqueous composition is transparent when being judged with the naked eye by an observer through a layer thickness of 1 cm.
