Abstract
The present invention relates to bar compositions in which an emollient composition comprising thickened entrapped emollient is added to a base bar composition at or during time of extrusion to form macroscopic, concentrated domains of emollient droplets. Addition of entrapped droplets allows far greater deposition than if the non-trapped emollients had been mixed in directly to form chips which are then extruded to form final bar.
Claims13
A bar composition consisting essentially of:
- (a) a bar phase comprising:
- (1) 5 to 90% of bar phase surfactant system;
- (2) 0.1 to 20% of bar phase water;
- (b) 1 to 60% by wt. of a stripe emollient composition comprising:
- (1) 20-80% polyalkylene glycol carrier;
- (2) 5-40% silicone;
- (3) 0.1-30% thickening agent;
- (4) 0-10% water;
- and
- (5) 0-15% structurant/filler;
- wherein said emollient (b)(2) is in the form of droplets entrapped in said carrier (b)(1) thickened with a thickening agent (b)(3) such that viscosity of said carrier is equal to or greater than 8000 cps;
- wherein said emollient droplets (b)(2) have size of at least 5 microns;
- and
- wherein said entrapped emollient droplets (b)(2) are concentrated to form domains when said carrier which contains the droplets is injected, extruded, coextruded, or otherwise inserted into said bar composition;
- wherein said domains are 1 micron to the width of bar in width and 1 micron to length of bar in length.
