ABSTRACT:
A non-irritating base component useful for cosmetics and topical preparations consisting of 2,6,10,15,19,23-hexamethyltetracosane having a high stability and being very safe for use on skin are hereby disclosed. Said component is synthesized by (a) preparing diacetylene dialcohol by reacting at least one ketone selected from the group consisting of 6,10-dimethylundecan-2-one, 6,10-dimethylundeca-3,9-dien-2-one, 6,10-dimethylundeca-5,9-dien-2-one, 6,10-dimethylundeca-5,10-dien-2-one and 6,10-dimethylundeca-3,5,9-trien-2-one, with acetylene and then subjecting the reaction product to the oxidation coupling, or by reacting ketone with diacetylene and (b) hydrocracking the diacetylene dialcohol directly or after hydrogenation.
