Claims20
A personal care rheological solid composition comprising:
- crystallizing agent and aqueous phase;
- wherein, the personal care rheological solid composition has a firmness between about 0.1 N to about 50.0 N as determined by the FIRMNESS TEST METHOD;
- a thermal stability of about 40° C. to about 95° C. as determined by the THERMAL STABILITY TEST METHOD;
- a liquid expression of between about 100 J m−3 to about 8,000 J m−3 as determined by the AQUEOUS PHASE EXPRESSION TEST METHOD;
- and
- wherein the crystallizing agent is a salt of fatty acids containing from about 13 to about 20 carbon atoms.
