Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
72 words
A composition comprising a complex obtained by mixing (i) at least one surfactant selected from ampholytic and semi-polar surfactants, and (ii) at least one higher fatty acid having an even number of carbon atoms and selected from lauric acid, myristic acid, stearic acid, palmitic acid, arachic acid, behenic acid, 2-palmitoleic acid, petroselinic acid, oleic acid, elaidic acid, ricinolic acid, linoleic acid, linoelaidic acid, linolenic acid, arachidonic acid, isostearic acid and 12-hydroxystearic acid.
Claim 2
Dependent Claim
18 words
A composition as claimed in claim 1, further comprising 0.01 to 5% by weight of a clay mineral.
Claim 3
Dependent Claim
126 words
A composition as claimed in claim 1 or 2, in which component (i) is selected from (A) amidobetaine ampholytic surfactants represented by the general formula: (B) amidosulfobetaine ampholytic surfactants represented by the general formula: (C) betaine ampholytic surfactants represented by the general formula: (D) sulfobetaine ampholytic surfactants represented by the general formula: (E) imidazolinium ampholytic surfactants represented by the general formula: (F) tertiary amine oxide semi-polar surfactants represented by the general formula: in which R₁ represents an alkyl or alkenyl group having 9 to 17 carbon atoms on average, R₂ represents an alkyl or alkenyl group having 10 to 18 carbon atoms on average, x is an integer of 2 to 4, y is an integer of 0 to 3, and z is 1 or 2.
