Abstract
Sulfonates of perfume alcohols are provided. The sulfonates have the general formulas of (I), (II), or combinations thereof: ##STR1## wherein R and Z are independently selected from the group consisting of nonionic or anionic, substituted or unsubstituted C.sub.1 -C.sub.30 straight, branched or cyclic alkyl, alkenyl, alkynyl, alkylaryl or aryl group; Y is a radical that, upon hydrolysis of said sulfonate, forms an alcohol with a boiling point at 760 mm Hg of less than about 300 .degree.C. which are perfumes. The sulfonates are employed as perfume components in laundry and cleaning compositions such as fabric softening compositions.
Claims19
Laundry and cleaning compositions comprising:
- (a) an amount, effective to provide a perfume effect, of a perfume component selected from the group consisting of sulfonates having the formula (I), (II), or combinations thereof:
- ##STR14## wherein R and Z are independently selected from the group consisting of nonionic or anionic, substituted or unsubstituted C.sub.1 -C.sub.30 straight, branched or cyclic alkyl, alkenyl, alkynyl, alkylaryl or aryl group;
- Y is a radical that, upon hydrolysis of said sulfonate, forms an alcohol with a boiling point at 760 mm Hg of less than about 300.degree. C. which are perfumes;
- and
- (b) ingredients useful for formulating laundry and cleaning compositions selected from the group consisting of cationic or nonionic fabric softening agents, enzymes, enzyme stabilizers, detersive surfactants, builders, bleaching compounds, polymeric soil release agents, dye transfer inhibiting agents, polymeric dispersing agents, suds suppressors, optical brighteners, chelating agents, fabric softening clays, anti-static agents, and mixtures thereof.
A fabric softening composition comprising:
- (a) an amount, effective to provide a perfume effect, of a perfume component selected from the group consisting of sulfonates having the formula (I), (II), or combinations thereof:
- ##STR15## wherein R and Z are independently selected from the group consisting of nonionic or anionic, substituted or unsubstituted C.sub.1 -C.sub.30 straight, branched or cyclic alkyl, alkenyl, alkynyl, alkylaryl or aryl group;

- and X.sup.- is a softener-compatible anion, the alkyl, or alkenyl, chain T.sup.1, T.sup.2, T.sup.3, T.sup.4, T.sup.5 must contain at least 11 carbon atoms.
A method for laundering soiled fabrics, said method comprising contacting a fabric with an aqueous medium containing at least about 50 ppm of a laundry composition comprising:
- (a) a perfume component selected from the group consisting of sulfonates having the formula (I), (II), or combinations thereof:
- ##STR19## wherein R and Z are independently selected from the group consisting of nonionic or anionic, substituted or unsubstituted C.sub.1 -C.sub.30 straight, branched or cyclic alkyl, alkenyl, alkynyl, alkylaryl or aryl group;
- Y is a radical that, upon hydrolysis of said sulfonate, forms an alcohol with a boiling point at 760 mm Hg of less than about 300.degree. C. which are perfumes;
