Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives.
A liquid detergent composition which comprises:
(A) at least one N-acylated acidic amino acid represented by general formula (I) or a salt thereof;
wherein R₁ represents an alkyl group or an alkenyl group having 7 to 21 carbon atoms; M₁ and M₂ each represents hydrogen, an alkali metal or an alkanolammonium ion; and m represents an integer of 1 or 2,
and (B) at least one aliphatic sulfonic acid selected from compounds represented by general formula (II) or (III) or salts thereof;
R₂-CH=CH(CH₂)nSO₃M₃ (II)
R₂--(CH₂)nCH₂SO₃M₃ (III)
wherein R₂ represents an alkyl group having 7 to 15 carbon atoms; n represents 0 or an integer of 1 to 5; and M₃ represents hydrogen, an alkali metal or an alkanolammonium ion;
wherein the ratio (A)/(B) of component (A) to component (B) is 3/7 to 7/3 by weight and the total concentration of component (A) and component (B) in the composition is in a range of 4 to 30 wt%.
