Abstract Processes and compositions are described for the use in perfume aroma augmenting, modifying, altering and enhancing compositions and as perfume and perfumed article aroma imparting materials of mixtures of (i) 2,2,6-trimethyl-1-cyclohexen-1-ylacetaldehyde (hereinafter referred to as "beta-cyclohomocitral") produced by a process which either (A) comprises the steps of: I. Oxidizing beta-ionone having the formula: ##STR1## with a peralkanoic acid having the formula: ##STR2## (wherein R is H, methyl or ethyl) in the presence of buffer and in the absence of dimethyl formamide, to form 2,2,6-trimethyl-1-cyclohexen-1-ylvinylacetate (hereinafter referred to as "beta-ionone enol ester") having the formula: ##STR3## ii. Hydrolyzing said beta-ionone enol ester using a basic hydrolysis agent to form beta-cyclohomocitral having the structure: ##STR4## or (B) oxidizing beta-ionone with hydrogen peroxide in the presence of inorganic base to form beta-cyclohomocitral directly, and (ii) one or two phenyl C 6 ketone which may be either or both 2,5-dimethyl-5-phenyl hexanone-4 (hereinafter termed "4-damascol") or 2,5-dimethyl-5-phenyl hexen-1-one-4 (hereinafter termed "damascol") having the generic structure: ##STR5## wherein the dashed line represents either a carbon-carbon single bond or a carbon-carbon double bond. Addition of mixtures of beta-cyclohomocitral and one or both phenyl C 6 ketones is indicated to modify, augment, impart or enhance in perfumes as well as in perfumed articles rosey, woody, camphoraceous, green and earthy notes.
A process for altering the aroma of a soap, which comprises adding thereto from 0.005% up to 10% by weight of said soap of a mixture consisting essentially of (i) 2,6,6-trimethyl-1-cyclohexen-1-ylacetaldehyde having the structure: ##STR21## and (ii) at least one phenyl C 6 ketone having the structure: ##STR22## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond, the ratio of 2,6,6-trimethyl-1-cyclohexen-1-ylacetaldehyde:phenyl C 6 ketone being in the range of from 1:1 up to 1.5.
