Abstract
Described is a stick shave formulation and article employing said formulation. The stick shave formulation contains a triethanolamine stearate soap formed in situ with from 1-10% of a nonionic wetting agent; from 1-15% of a silicone copolymer; from 0.1-1% of a polyoxyethylene polymer slip agent; from 1-30% of a synthetic detergent; from 2-10% of a whitening agent; and 5-20% of emollient moisturizers and hair lubricants.
Claims3
A method for forming a solid phase shaving stick article which continuously retains the solid phase at ambient conditions prior to, during and subsequent to the use thereof, comprising the steps of:
- (i) intimately admixing stearic acid, and emollient moisturizer, a synthetic detergent and a nonionic wetting agent thereby forming a first mixture;
- (ii) heating the first mixture until a melt is formed thereby forming a first melt;
- (iii) admixing a whitening agent with said first melt thereby forming a second mixture;
- (iv) intimately admixing a silicone copolymer, a hair lubricant, a polyoxyethylene polymer slip agent and triethanolamine in order to form a third mixture;
- (v) heating said third mixture until a second melt is formed;
- (vi) mixing said second melt with a synthetic detergent thereby forming a fourth mixture;
- (vii) intimately admixing said fourth mixture with said second mixture thereby forming a fifth mixture;
- (viii) admixing said fifth mixture with a perfume material thereby forming a sixth mixture;
- and
- (ix) pouring said sixth mixture into molds and allowing the resulting articles to cool and harden
- whereby the resulting shaving stick formulation consists essentially of:
- (i) from about 1 up to about 10% by weight of a nonionic wetting agent;
- (ii) from about 1 up to about 15% by weight of a silicone copolymer;
- (iii) from about 0.1 up to about 1% by weight of a polyoxyethylene polymer slip agent;
- (iv) from about 1 up to about 30% of a synthetic detergent;
- (v) from about 2 up to about 10% by weight of a whitening agent;
- and
- (vi) from about 5 up to about 20% by weight of an emollient moisturizer and hair lubricant
- with the remainder being triethanolamine stearate.
A method of producing and applying a solid shaving stick formulation which method comprises the steps of:
- (a) carrying out the process comprising the steps of:
- (i) intimately admixing stearic acid, an emollient moisturizer, a synthetic detergent and a nonionic wetting agent thereby forming a first mixture;
- (ii) heating the first mixture until a melt is formed thereby forming a first melt;
- (iii) admixing a whitening agent with said first melt thereby forming a second mixture;
- (iv) intimately admixing a silicone copolymer, a hair lubircant, a polyoxyethylene polymer slip agent and triethanolamine in order to form a third mixture;
- (v) heating said third mixture until a second melt is formed;
- (iv) mixing said second melt with a synthetic detergent thereby forming a fourth mixture;
- (vii) intimately admixing said fourth mixture with said second mixture thereby forming a fifth mixture;
- (viii) admixing said fifth mixture with a perfurme material thereby forming a sixth mixture;
- and
- (ix) pouring said sixth mixture into molds and allowing the resulting articles to cool and harden;
- (b) applying the resulting shaving stick to skin to be shaved;
- and
- (c) shaving the skin after such application.
