Unsaturated fatty alcohol derivatives from natural oil metathesis

A sulfate composition comprising:

• (a) 40 to 60 wt. % of a monounsaturated C10 or C12 primary alcohol sulfate of the formula
• (b) 40 to 60 wt. % of a C10 or C12 secondary hydroxyalkyl primary alcohol sulfate of the formula
• and
• (c) 0.1 to 20 wt. % of sulfonated products;
• wherein X in each formula is a mono- or divalent cation or an ammonium or substituted ammonium cation;
• wherein the sulfate composition is made by falling-film sulfation using sulfur trioxide of a C10 or C12 monounsaturated primary alcohol of the formula
• and
• wherein cross-polarized light microscopy examination at 100× to 400× and 20-22° C. of aqueous mixtures comprising the sulfate composition reveals an isotropic clear phase at all actives levels up to 50 wt. % actives.
