Eastman Tenox™ Personal Care Antioxidants

Food-Grade Antioxidants for Cosmetics

Eastman Tenox™ food-grade antioxidants inhibit the rancidity of creams and lotions for a variety of personal care products including skin care, sun care, hair care, color cosmetics, fragrances, antiperspirants, and deodorant.

Tenox™ Antioxidant Composition & Characteristics

TBHQ = Tertiary-Butylhydroquinone
BHT = Butylated Hydroxytoluene
BHA = Butylated Hydroxyanisole

Tenox™ Formulation & Processing Tips

For cosmetics and personal care products, the optimum level of antioxidant ranges from 0.02% to 0.1%.

Tenox™ TBHQ forms colored complexes with amines in fatty acid/amine emulsifier systems at alkaline pH so some discoloration may occur. To prevent discoloration, Eastman suggests neutralizing acids with amines to a pH of 7 or less.

Tenox™ Antioxidant Effectiveness

The oil stability index (OSI) is an automated, accelerated method of measuring the effect of antioxidants on the stability of fats and oils.  The induction period is recorded as the number of hours at which rapid acceleration of oxidation occurs.  These charts show the effect of Tenox™ in comparison to other antioxidants on the oxidation of popular oils.

This data is also available for other oils, just CONTACT US for more details or for help with your cosmetics formulations.
