Claim 0:
1. A moisturizing composition comprising:
about 0.001% to about 6% (w/v) of silk fibroin-based protein fragments that are substantially devoid of sericin,
about 0.1% to about 25% (v/v) of an oil, and
about 99% to about 70% (v/v) water;
wherein a pH of the moisturizing composition is in the range of about 1.0 to about 8.0,
wherein the silk fibroin-based protein fragments have an average weight average molecular weight ranging from about 5 kDa to about 80 kDa, and
wherein the silk fibroin-based protein fragments have a polydispersity of between about 1.5 and about 3.0, and
wherein the silk fibroin-based protein fragments do not spontaneously or gradually gelate and do not visibly change in color or turbidity when in an aqueous solution for a period of time in the range of four weeks to 52 weeks at room temperature.
