The New Generation of Vegetable-Based Esters!


Strahl & Pitsch has introduced a new series of vegetable derived esters for Cosmetic & Personal Care use. Puresters are produced domestically from naturally derived fatty alcohol & methyl ester feedstocks which are non-GMO vegetable based renewable resources.  The quality and availability of Puresters are very consistent and they're readily available in a variety of packaged forms and bulk liquid. Due to these qualities, the pricing of Puresters remains stable.
 
Benefits include:
Low IV (2-4) provides good chemical and thermal stability. Enhanced emulsion stability.
Provides a talc-powder like after-feel in some applications. Excellent film former (increases substantivity).
Cost savings vs. other natural esters and emollients. Reduces the greasy feel of oil systems.
Provides enhanced whiteness in creams and lotions vs. microcrystalline waxes (C34 & C40). Improves payoff characteristics in sticks (lipstick, AP, etc.)
The precise thermal profile suits them for use in color cosmetics, hair care, lotions, creams, moisturizers, cleansers, bath oils and scrubs, AP / deodorant sticks, and sunscreens.
