Powerful Skin and Oil Antioxidant

The Story

Sustainably sourced rosemary-extract for Cosmetics ingredients

For Kemin, the secret of beautiful skin is the use of antioxidants. Skin needs defenses against “outside-in” and  “inside-out” oxidative stresses coming from exposure to environmental aggressors and sugar consumption that dramatically speed up the extrinsic aging process as a result of photo-aging and glycation. Kemin has created Rosamox, a powerful natural antioxidant made from rosemary extract, that provides protection against UV stress and glycation and reduces the accumulation of skin damage overtime, for healthy looking skin.

Formulating oil-based products with Kemin Industries

Moreover, oils most commonly used in personal care products are often of plant origin and highly unsaturated. This makes them susceptible to oxidation, leading to final product degradation over time, and a shorter shelf life. To overcome oxidation challenges, the use of antioxidants to protect oils and formulas is necessary. Rosamox is a very effective natural antioxidant with stunning long-term oil preservation. Kemin has tested Rosamox against synthetic butylated hydroxytoluene (BHT) and tocopherol acetate. The test shows significant protection of highly unstable oils, resulting in an efficacious natural alternative, while providing an attractive label copy.

Many rosemary extracts lack consistency in terms of the level of active antioxidants. The rosemary plants Kemin has selected to create Rosamox are based on the highest possible antioxidant targeted molecule levels that all work together to provide optimal and consistent skin and formula benefits.
