Abstract
The present invention relates to non-aerosol shaving compositions which are free of propellants, and methods of preparing and using such shaving composition. In particular, the present invention relates to a non-aerosol, propellant-free composition comprising: (i) at least two C14 to C16 carboxylic acids or an alkali metal salt thereof; (ii) at least one compound of general Formula (I) R—O—[—CH2CH2O—]n—CH2CO2H (I) or an alkali metal salt thereof, wherein R represents a saturated, straight- or branched-chain C10 to C18 alkyl group; and n represents an integer between 4 and 12; (iii) polyvinyl pyrrolidone; and (iv) water.
Claims29
A propellant-free composition comprising:
- (i) two or more carboxylic acids including at least one C14 carboxylic acid or alkali metal salt thereof, present in an amount of about 1.6 wt. % to about 5.0 wt. %, based on the weight of the entire composition, and at least one C16 to C18 carboxylic acid or alkali metal salt thereof and excluding a C12 carboxylic acid comprising lauric acid or alkali metal salt thereof, wherein a ratio of the at least one C14 carboxylic acid or alkali metal salt thereof to one of the at least one C16 to C18 carboxylic acid or alkali metal salt thereof is from about 1:2 to about 2:1;
- (ii) at least one compound of general Formula (I):
- R—O—[—CH2CH2O—]n—CH2CO2H
- or alkali metal salt thereof, wherein R represents a straight- or branched-chain, saturated C10 to C18 alkyl group, n represents an integer between 4 and 12, and the at least one compound of general Formula (I) is present in an amount of about 2.5 wt. % to about 10.0 wt. %, based on the weight of the entire composition;
- (iii) polyvinyl pyrrolidone;
- and
- (iv) water.
A propellant-free composition comprising:
- (i) two or more carboxylic acids including at least one C16 carboxylic acid or alkali metal salt thereof, present in an amount of about 1.6 wt. % to about 3.3 wt. %, based on the weight of the entire composition, and at least one C18 carboxylic acid or alkali metal salt thereof and excluding a combination of a C12 carboxylic acid comprising lauric acid or alkali metal salt thereof and a C14 carboxylic acid or alkali metal salt thereof comprising myristic acid or alkali metal salt thereof, wherein a ratio of the at least one C16 carboxylic acid to the at least one C18 carboxylic acid is from about 1:2 to about 2:1;
- (ii) at least one compound of general Formula (I):
- R—O—[—CH2CH2O—]n—CH2CO2H
- or alkali metal salt thereof, wherein R represents a straight- or branched-chain, saturated C10 to C18 alkyl group, n represents an integer between 4 and 12, and the at least one compound of general Formula (I) is present in an amount of about 2.5 wt. % to about 10.0 wt. %, based on the weight of the entire composition;
- (iii) polyvinyl pyrrolidone;
- and
- (iv) water.
