A photo protective topical composition, comprising: (i) at least one functional active; and (ii) at least one solubilizing compound having the structure of Formula I: wherein R is C-Ccycloalkyl or linear or branched alkylcycloalkyl, wherein the ring size is C-C; R, R, and Rare each independently selected from the group consisting of H, and linear or branched C-Calkyl, provided that at least two of R, R, Rare H; wherein the solubilizing compound is present in an amount effective to solubilize said functional active. Also disclosed is a method for treating skin, lips, nails, hair, ears, eyelashes, eyebrows and/or scalp with an effective amount of composition.

Solubilizing agents for active or functional organic compounds

This invention relates to non-hydrolyzable, non-irritating, hair, skin and textile substantive quaternary ammonium salts of a para-dialkylamino benzamide having the formula ##STR1## wherein R' and R' are each selected from the group of C.sub.1 to C.sub.2 alkyl; n is an integer having a value of from 2 to 6; R is an alkyl radical having from 1 to 30 carbon atoms; R.sub.1 and R.sub.2 are each selected from the group of C.sub.1 to C.sub.4 alkyl, hydrogen and, alternatively, R.sub.1 and R.sub.2, together with the attached cationic nitrogen atom can form a 5 to 6-membered heterocyclic ring selected from the group of ##STR2## and X is an anion. These benzamide derivatives are active sunscreening agents which are usefully employed at a concentration of from about 0.5 to about 10 wt. % in a formulation requiring protection against the harmful effects of sunlight, such as skin burn, hair damage, color fading, etc.

Quaternary salts of para-dialkylamino benzamide derivatives

This invention relates to non-hydrolyzable, non-irritating, hair, skin and textile substantive quaternary ammonium salts of a para-dialkylamino benzamide having the formula ##STR1## wherein R' and R' are each selected from the group of C.sub.1 to C.sub.2 alkyl; n is an integer having a value of from 2 to 6; R is an alkyl radical having from 1 to 30 carbon atoms; R.sub.1 and R.sub.2 together with the attached cationic nitrogen atom forms a 5 to 6-membered heterocyclic ring containing a hetero oxygen atom in addition to the heteronitrogen atom and is selected from the group of ##STR2## and X is an anion. These benzamide heterocyclic derivatives are active sunscreening agents which are usefully employed at a concentration of from about 0.5 to about 10 wt. % in a formulation requiring protection against the harmful effects of sunlight, such as skin burn, hair damage, color fading, etc.

Heterocyclic quaternary salts of para-dialkylamino benzamide derivatives

This invention relates to non-hydrolyzable, non-irritating, hair, skin and textile substantive quaternary salts of p-dialkylaminobenzamides having the formula ##STR1## wherein R' and R' are each selected from the group of C.sub.1 to C.sub.2 alkyl; n is an integer having a value of from 2 to 3; R is an alkyl radical having from 10 to 18 carbon atoms; R.sub.1 and R.sub.2 are each selected from the group of C.sub.1 to C.sub.2 alkyl, and X is an anion. These benzamide derivatives are active sunscreening agents which are usefully employed at a concentration of from about 0.5 to about 10 wt. % in a formulation requiring protection against the harmful effects of sunlight, such as skin burn, hair damage, color fading, etc.
