Use of mixture of aliphatic C.sub.10 branched olefins in augmenting or enhancing the aroma of perfumed alkaline metal hypochlorite solutions

#The instant invention provides mixtures of C.sub.10 branched chain olefins which are used to augment or enhance the aroma of perfume compositions, colognes and perfumed articles.

#Chemical compounds which can provide a woody, piney and herbaceous aroma are desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfumery compositions are high in cost, unobtainable at times, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

#There is, accordingly, a continuing effort to find synthetic materials which will replace, enhance or augment the fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of the synthetic materials either have the desired nuances only to a relatively small degree, or they contribute undesirable or unwanted odor to the compositions.

#It has now been determined that dimers of isoamylene produced according to the reaction: ##STR2## wherein one of the dashed lines in each of the molecules is a carbon-carbon double bond and the other of the dashed lines in each of the molecules is a carbon-carbon single bond, are capable of imparting or augmenting or enhancing a variety of fragrances to consumable materials.

#Briefly our invention contemplates augmenting or enhancing fragrances of such consumable materials as perfumes, perfumed articles (e.g. solid or liquid anionic, cationic, nonionic or zwitterionic detergents, cosmetic powders, fabric softener compositions and dryer-added fabric softener articles) and colognes by adding thereto, a small, but effective amount of at least one of the compounds defined according to one of the generic structures: ##STR3## wherein, in each of the molecules, one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is a carbon-carbon single bond.

#The di-isoamylene compounds of our invention augment or enhance woody, piney and herbaceous aroma characteristics of perfumes, perfumed articles and colognes, thereby causing one or more of said di-isoamylene compounds to be useful particularly in pine fragrances.
