ABSTRACT:
Gelling agents which contain a specific N-acylamino acid monoamide monoalkyl ester have a melting temperature of about 100° C., are capable of solidifying a wide variety of oily base materials including silicones, and do not cause “sweating” while retaining a practical level of gel strength. When applied to skin, the resulting gels have a good feeling, good spreadability, and good fittability to skin.
