Abstract
The present invention includes a clear cosmetic stick that has a clarity that is stable over a temperature of 5 to 45 degrees Centigrade for a time period of at least about twelve months. The clear cosmetic stick includes one or more of a branched chain fatty acid surfactant and a straight-chain fatty alcohol surfactant.
Claims22
A clear cosmetic stick, comprising:
- one or more of a branched chain fatty acid surfactant, a straight-chain fatty alcohol surfactant, and a polyhydric alcohol in a concentration effective for maintaining clarity over a temperature range of 5 to 45 degrees Centigrade for a time period of at least twelve months.
A clear cosmetic stick formulation, comprising a branched chain fatty acid surfactant and a straight chain fatty alcohol surfactant in a concentration effective for maintaining clarity over a temperature range of 5 to 45 degrees Centigrade for a time period of at least twelve months.
A method for making a clear cosmetic stick, comprising:
- providing a polyhydric alcohol and a deodorant active material and mixing the polyhydric alcohol with the deodorant active material together to form a deodorant active mixture;
- adding a soap, gel forming agent to the deodorant mixture to form a gelled mixture;
- adding one or more of a branched chain fatty acid surfactant and a straight chain alcohol surfactant to the gelled mixture to impart clarity to the mixture for a time period of at least 12 months at temperatures of up to 5 to 45 degrees Centigrade;
- adding sodium hydroxide to the clarified mixture;
- and
- pouring the clarified mixture into a container to impart a clear stick conformation to the clarified mixture.
A method for stabilizing clarity in a clear cosmetic stick, comprising:
- providing ingredients effective for making a clear cosmetic stick;
- preparing a mixture comprising one or more of a branched chain fatty acid surfactant and a straight chain alcohol surfactant;
- and
- adding the mixture to the ingredients in a concentration effective to stabilize clarity of the clear cosmetic stick for at least about 12 months at temperatures as high as 45 degrees Centigrade.
A clear fragrance stick comprising one or more of a branched chain fatty acid surfactant, a straight-chain fatty alcohol surfactant, a fragrance oil in a concentration of about 5.5 to 10 percent by volume, and a polyhydric alcohol in a concentration effective for maintaining clarity for a time period of at least about four months
A clear blush stick comprising one or more of a branched chain fatty acid surfactant, a straight-chain fatty alcohol surfactant, a color in a concentration range of about 0.05 to 0.10 percent by volume, and a polyhydric alcohol in a concentration effective for maintaining clarity for a time period of at least about one month.
