Abstract
A low-water composition comprising a solid dissolvable composition domain having a crystallizing agent and a PEGC domain.
Claims15
A low-water composition, comprising:
- 1) At least one solid dissolvable composition domain (SDC) comprising a crystallizing agent;
- 2) at least one polyethylene glycol domain (PEGC);
- 3) freshness benefit agent;
- and
- wherein the crystallizing agent is a sodium salt of saturated fatty acids having from 8 to about 12 carbon atoms;
- wherein the freshness benefit agent is present in at least one of the SDC or PEGC;
- wherein the low-water composition has a water content of less than about 10 wt. %;
- and
- wherein the sodium salt of saturated fatty acids of the crystallizing agent comprises from 50 wt. % to 70 wt. % C12, 15 wt. % to 25 wt. % C10, and 15 wt. % to 25 wt. % C8 wherein the freshness benefit agent is encapsulated in a capsule having a wall and a core;
- and
- wherein the capsules have a volume-weighted median capsule size from about 1 to about 100 microns.

A method of producing a low-water composition comprising:
- a) Mixing-heating crystallizing agent(s) and an aqueous phase until the crystallizing agent is substantially solubilized, cooling to a temperature before significant crystallization of the crystallizing agent in the form of SDCM;
- b) Forming—the SDC into the designed shape and size, by cooling the Solid Dissolvable Composition Mixture to below the Crystallization Temperature, and allowing the Solid Dissolvable Composition Mixture to crystallize into an intermediate rheological solid;
- c) Drying-removing excess water and producing a solid dissolvable composition (SDC) by removing between about 90% to about 99% of the water as determined by the MOISTURE TEST METHOD from the intermediate rheological solid composition to produce a solid dissolvable composition having an average solubility percent greater than 5% at 37° C., as determined by the DISSOLUTION TEST METHOD;
- d) providing polyethylene glycol (PEGC);
- e) combining the SDC and PEGC to produce a low-water composition having an SDC Domain and a PEGC Domain;
- wherein a freshness benefit agent is added to at least one of the SDC Domain or the PEGC Domain
- wherein sodium salt of saturated fatty acids of the crystallizing agent(s) comprises from 50 wt. % to 70 wt. % C12, 15 wt. % to 25 wt. % C10, and 15 wt. % to 25 wt. % C8.
