Abstract
Disclosed are cosmetic gel-solid stick compositions comprising particulate antiperspirant active, a fatty acid gellant having a select dimer-to-monomer ratio and an optional secondary gellant, and an anhydrous liquid carrier. The select dimer-to-monomer ratio of the fatty acid gellant helps provide the composition with improved hardness, low residue performance and efficacy, especially when used in combination with a secondary gellant.
Claims22
An anhydrous antiperspirant gel-solid stick composition comprising:
- (a) from about 0.5% to about 60% by weight of particulate antiperspirant active;
- (b) from about 1% to about 15% by weight of a fatty acid gellant having a dimer-to-monomer ratio of from about 2.5:1 to about 25:1 and less than 0.5% of n-acyl amino acid gellants;
- and
- (c) from about 10% to about 80% by weight of an anhydrous liquid carrier having an average solubility parameter of from about 3 to about 13 (cal/cm.sup.3).sup.0.5.
The composition of claim I wherein the composition has a hardness of from about 500 gram.force to about 5000 gram.force, a visible residue index of from about 11 to about 30 L-value, and an elastic to viscous moduli ratio of from about 0.1 to about 100.
An anhydrous antiperspirant gel-solid stick composition comprising:
- (a) from about 0.5 % to about 85 % by weight of a particulate antiperspirant active;
- (b) from about 1% to 15% by weight of a fatty acid gellant having a dimer-to-monomer ratio of from about 4:1 to about 25:1 and a n-acyl amino acid secondary gellant;
- and
- (c) from about 0.1 % to about 70 % by weight of an anhydrous liquid carrier having a solubility parameter from about 5 to about 13 (cal/cm.sup.3).sup.0.5.
An anhydrous antiperspirant composition comprising:
- (a) from about 0.5% to about 60% by weight of particulate antiperspirant active;
- (b) from about 1% to about 15% by weight of a fatty acid gellant having a dimer-to-monomer ratio of from about 25:1 to about 25:1;
- and
- (c) from about 10% to about 80% by weight of an anhydrous liquid carrier having an average solubility parameter of from about 3 to about 13 (cal/cm.sup.3).sup.0.5 and
- wherein the composition has a hardness of from about 20 gram.force to about 500 gram force.
A method for treating or reducing perspiration wetness and malodor, comprising applying from about 0.1 gram to about 20 grams of the composition of claim I to the desired area of the skin.
