Abstract

Described is a process for imparting an "air dried cloth" aroma to cloth, synthetic or natural, previously dried using a clothes drier, comprising the step of contacting the cloth prior to drying with an aroma augmenting or enhancing quantity of either (i) a mixture consisting essentially of:

(a) from about 0.5 up to about 5% by weight of said composition of n-hexanal;

(b) from about 2 up to about 12% by weight of said composition of n-heptanal;

(c) from about 5 up to about 15% by weight of said composition of n-octanal;

(d) from about 40 up to about 70% by weight of said composition of n-nonanal;

(e) from about 10 up to about 30% by weight of said composition of n-decanal;

(f) from about 0.5 up to about 5% by weight of said composition of n-undecanal;

(g) from about 0.5 up to about 5% by weight of said composition of n-dodecanal;

(h) from about 0.5 up to about 5% by weight of said composition of n-tridecanal;

(i) from about 0 up to about 5% by weight of said composition of n-tetradecanal;

(j) from about 0 up to about 5% by weight of said composition of n-pentadecanal;

or (ii) first contacting the cloth with at least one organic acid selected from the group consisting of oleic acid, linoleic acid, and linolenic acid or a glyceride ester thereof, then exposing the resultant treated cloth to air and light in the ultra violet wavelengths prior to drying. Also described is a process for augmenting or enhancing the aroma of consumable materials selected from the group consisting of perfume compositions, colognes and perfumed articles (e.g. perfumed polymers, solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles and hair preparations) by intimately admixing with the perfume composition, cologne or perfumed article composition or component, an aroma augmenting or enhancing quantity of a mixture consisting essentially of the same mixture of C₇ -C₁₀ straight chain aldehydes as given above.
