Abstract
Disclosed are hair grooming compositions or formulations comprising at least one carboxyalkyl cellulose (CAC) ester such as carboxyalkyl cellulose acetate butyrate or acetate propionate and methods for the use thereof. The liquid compositions may be applied to hair in the form of a spray, mist, gel or mousse to facilitate styling of the hair.
Claims13
A hair grooming composition comprising:
- (1) about 0.5 to 10 weight percent of a partially or totally neutralized carboxyalkyl cellulose ester;
- and (2) about 85 to 99.5 weight percent of a liquid vehicle comprising about 0 to 96 weight percent water and about 4 to 100 weight percent of an alkanol having 2 or 3 carbon atoms;
- wherein
- the carboxyalkyl cellulose ester of component (1) is a C2-C4 alkanoate ester of carboxy(C1-C3-alkyl)cellulose having an inherent viscosity of about 0.2 to 0.7 dL/g as measured in a 60/40 by weight solution of phenol/tetrachloroethane at 25° C., a degree of substitution per anhydroglucose unit of carboxy(C1-C3-alkyl) of greater than 0.2 to about 0.75, and a degree of substitution per anhydroglucose unit of C2-C4 alkanoate estert residue of about 1.5 to 2.7;
- and
- about 40 to 90 mole percent of the carboxy groups of the carboxyalkyl cellulose ester of component (1) are neutralized with a base.

A hair grooming composition comprising:
- I. about 0.5 to 10 weight percent of a partially or totally neutralized carboxyalkyl cellulose ester;
- II. about 0.5 to 10 weight percent of a sulfonate-containing, linear polyester;
- and
- III. about 85 to 99 weight percent of a liquid vehicle comprising about 0 to 96 weight percent water and about 4 to 100 weight percent of an alkanol having 2 or 3 carbon atoms;
- wherein
- the carboxyalkyl cellulose ester of component (1) is a C2-C4 alkanoate ester of carboxy(C1-C3-alkyl)cellulose having an inherent viscosity of about 0.2 to 0.7 dL/g as measured in a 60/40 by weight solution of phenol/tetrachloroethane at 25° C., a degree of substitution per anhydroglucose unit of carboxy(C1-C3-alkyl) of greater than 0.2 to about 0.75, and a degree of substitution per anhydroglucose unit of C2-C4 alkanoate estert residue of about 1.5 to 2.7;
- about 40 to 90 mole percent of the carboxy groups of the carboxyalkyl cellulose ester of component (1) are neutralized with a base;
- and the sulfonate-containing, linear polyester is comprised of:
- (i) diacid monomer residues comprising residues of at least one dicarboxylic acid;
- (ii) about 4 to 26 mole percent, based on the total of all acid, hydroxy and amino equivalents, of monomer residues of at least one difunctional sulfo monomer containing at least one sulfonate group bonded to an aromatic ring where the functional groups are hydroxy, carboxy or amino;
- and
- (iii) monomer residues of at least one diol or a mixture of a diol and diamine comprising:
- (a) at least 15 mole percent, based on the total mole percent of diol monomer residues or diol and diamine monomer residues, of a diol having the formula —(OCH2CH2)n— wherein n is 2 to about 10;
- or
- (b) about 0.1 to less than about 15 mole percent, based on the total mole percent of diol monomer residues or diol and diamine monomer residues, of monomer residues of a poly(ethylene glycol) having the formula —(OCH2CH2)n— wherein n is 2 to about 500, provided that the mole percent of such residues is inversely proportional to the value of n;
- and, optionally
- (iv) monomer residues of at least one difunctional monomer reactant selected from hydroxycarboxylic acids, aminocarboxylic acids and aminoalkanols;
- provided that at least 20% of the groups linking the monomeric units are ester, i.e., carbonyloxy linkages.
