Abstract
Described are methods for augmenting or enhancing the aroma of perfumes and perfumed articles by adding thereto perfume aroma augmenting or enhancing quantities of novel C.sub.10 -branched olefin epoxide mixtures produced by dimerizing isoamylene, (2-methyl-2-butene) and then epoxidizing the resulting product; as well as perfume compositions, colognes and perfumed articles including solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, hair preparations and deodorant compositions as well as bleaching compositions containing same.
Claims2
A process for augmenting or enhancing the aroma of a solid or liquid anionic, cationic, nonionic or zwitterionic detergent comprising the step of adding to a solid or liquid anionic, cationic, nonionic or zwitterionic detergent base an aroma augmenting or enhancing quantity of at least one epoxide compound defined according to the structure:
- ##STR32## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are the same or different and each represents hydrogen or methyl with the proviso that (i) the sum total of carbon atoms in R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 is three, and (ii) R.sub.1 and R.sub.2 represent hydrogen when R.sub.5 represents methyl, and (iii) when either R.sub.1 or R.sub.2 is methyl, R.sub.5 is hydrogen.
A process for augmenting or enhancing the aroma of a solid or liquid anionic, cationic, nonionic or zwitterionic detergent comprising the step of adding to a solid or liquid anionic, nonionic, cationic or zwitterionic detergent base an aroma augmenting or enhancing quantity of a composition comprising epoxide compounds produced according to the process comprising the steps of reacting isoamylene having the structure:
- ##STR33## with a Lewis acid or a mineral acid to form a mixture of diisoamylenes having the structures:
- ##STR34## and then reacting the said mixture of diisoamylenes with a peracid in order to form a mixture of epoxides having the structures:
- ##STR35##
