Shave care composition for a liquid dispensing razor
A liquid dispensing razor including a reservoir containing a shave care composition. The shave care composition comprises water; one or more lipophilic skin conditioning agents; one or more thickening agents including electrolyte sensitive polymers; one or more emulsifying agents; and one or more lubricants. The shave care composition is delivered to the skin by the razor to provide skin comfort and moisturization benefits during the shave. The combination of the chemistry in the razor results in step change in skin condition in consumer and technical skin moisturization benefits.
1. A liquid dispensing razor comprising:
a razor cartridge including a housing, the housing defining at least one aperture and including microcombs and at least one blade, the microcombs being disposed between the at least one blade and the aperture; and
a reservoir in fluid communication with the aperture, the reservoir containing a shave care composition, the shave care composition comprising:
water;
from 15% to about 50%, by weight, of one or more lipophilic skin conditioning agents;
one or more thickening agents including electrolyte sensitive polymers;
one or more emulsifying agents; and
one or more lubricants;
wherein the shave care composition has a Power-Law Consistency of less than about 38 Pa·s and greater than about 23 Pa·s, such that the shave care composition is dispensable from the reservoir through the at least one aperture and capable of being distributed by the microcombs adjacent the at least one blade.
2. The liquid dispensing razor of claim 1 , wherein the composition comprises from about 0.1% to about 5%, by weight, of the one or more thickening agents.
3. The liquid dispensing razor of claim 1 , wherein the composition comprises from about 0.1% to about 20%, by weight, of the one or more emulsifying agents.
4. The liquid dispensing razor of claim 1 , wherein the composition comprises from about 0.1% to about 8%, by weight, of the one or more lubricants.
5. The liquid dispensing razor of claim 1 , further comprising salicylic acid.
6. The liquid dispensing razor of claim 5 , wherein the composition comprises from about 0.001% to about 5%, by weight, of the salicylic acid.
7. The liquid dispensing razor of claim 1 wherein the electrolyte sensitive polymer is selected from the group consisting of Polyacrylamide, Hydroxyethyl Acrylate/Sodium Acryloyldimethyltaurate Copolymer, Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Ammonium Polyacrylate, Sodium Acrylate/Acryloyldimethyltaurate/Dimethylacrylamide Crosspolymer, Hydroxyethyl Acrylate/Sodium Acryloyldimethyltaurate Copolymer, Carboxylic Acid Polymers, Ammonium Acryloyldimethyltaurate/VP Copolymer, Sodium Acryloyldimethyltaurate/VP Copolymer, Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer.
8. The liquid dispensing razor of claim 1 wherein the electrolyte sensitive polymer is Polyacrylamide.
9. The liquid dispensing razor of claim 1 wherein the lipophilic skin conditioning agent is comprised of pre-blended lipid materials.
10. The liquid dispensing razor of claim 9 where the pre-blend is composed of Petrolatum with another lipid oil chosen from mineral oil or a fatty acid ester.
11. The liquid dispensing razor according to claim 1 wherein the shave care composition has a Power-Law Index of less than about 0.5 and a Power-Law Consistency of greater than about 25 Pa·s.
12. The liquid dispensing razor according to claim 11 wherein the Power-Law Consistency is greater than about 30 Pa·s.
13. A liquid dispensing razor comprising:
a razor cartridge including a housing, the housing defining at least one aperture and including microcombs and at least one blade, the microcombs being disposed between the at least one blade and the aperture; and
a reservoir in fluid communication with the aperture, the reservoir containing a shave care composition, the shave care composition comprising:
water;
from 15% to about 50%, by weight, of one or more lipophilic skin conditioning agents;
from about 0.1% to about 5%, by weight, of one or more thickening agents;
from about 0.1% to about 20%, by weight, of one or more emulsifying agents; and
from about 0.1% to about 8%, by weight, of one or more lubricants;
wherein the shave care composition has a Power-Law Consistency of less than about 38 Pa·s and greater than about 23 Pa·s, such that the shave care composition is dispensable from the reservoir through the at least one aperture and capable of being distributed by the microcombs adjacent the at least one blade.
14. The liquid dispensing razor of claim 13 , wherein the composition comprises from about 0.25% to about 3%, by weight, of the one or more thickening agents.
15. The liquid dispensing razor of claim 13 , wherein the composition comprises from about 1.0% to about 12%, by weight, of the one or more emulsifying agents.
16. The liquid dispensing razor of claim 13 , wherein the composition comprises from about 0.2% to about 3%, by weight, of the one or more lubricants.
