Encapsulates

摘要

The present application relates to encapsulated, solid, water soluble benefit agents and products comprising such encapsulates, as well as processes for making and using such encapsulates and products comprising such encapsulates. In one aspect, the present application relates to a melamine formaldehyde and/or urea formaldehyde encapsulation process that offers as solution to the dissolution of solid, water soluble benefit agents during the process's emulsification step.

1. A process of making a consumer product that comprises a consumer product adjunct material and a particle, said process comprising:
a) preparing a first solution comprising, based on total solution weight, from about 10% to about 90%, a first emulsifier and a first resin, the weight ratio of said first emulsifier and said first resin being from about 0.1:1 to about 10:1; b) adjusting the pH of the first solution to be in the range of from about pH 4.5 to pH 6; c) preparing a second solution comprising based on total solution weight from about 10% to about 95% water, a second emulsifier and a second resin, the weight ratio of said second emulsifier and said second resin being from about 0:1 to about 3:1; d) adjusting the pH of the second solution to be in the range of from pH 4 to pH 6; e) preparing a core material comprising a solid water soluble benefit agent, a protective suspension agent having a viscosity, at 25° C., of at least 500 centistokes, and, optionally, a hydrophobic organic material, said protective suspension agent coating said solid water soluble benefit agent; f) combining said core material and said first solution to form a first composition; g) emulsifying said first composition; h) combining said first composition and said second solution to form a second composition and optionally combining any processing aids and said second composition; i) mixing said second composition for at least 15 minutes at a temperature of from about 25° C. to about 100° C. and optionally combining any processing aids to said second composition; j) optionally combining any scavenger material, structurant, salts and/or anti-agglomeration agent with said second composition during step i) or thereafter; k) optionally spray drying or agglomerating said second composition; l) combining said second composition with one or more consumer product adjuncts.
