We supply Hydroxyacetophenone cosmetic grade as INNO Proextend Hydroxyacetophenone, a cosmetic-grade antioxidant and preservation-support ingredient.
Key Benefits of Proextend Hydroxyacetophenone
- Proextend Hydroxyacetophenone is a preservation booster for systems designed without parabens, formaldehyde releasers or MIT. It supports modern multi-component preservation without acting as a conventional listed preservative.
- The material contributes antioxidant, soothing and skin-conditioning effects. In amino-acid and taurinate cleansers, it can soften irritation and improve the comfort of the finished wash.
- Its antioxidant activity helps neutralize free radicals and protect formula components from oxidation. This gives it a useful secondary role in serum, cream, sunscreen and color-cosmetic systems.
- Hydroxyacetophenone works particularly well with 1,2-Hexanediol, Ethylhexylglycerin and Caprylhydroxamic Acid. These combinations cover complementary microbial and sensory needs.
- INNO has mature preservation platforms using this material. The application team can adjust the combination and run challenge testing against the customer’s complete formula.
Recommended applications
- Use Proextend Hydroxyacetophenone in serum, toner, cream and lotion when antioxidant support and preservation boosting are needed together.
- It suits facial mask, sunscreen and foundation where the formula contains oxidation-sensitive materials and requires a controlled sensory profile.
- In facial cleanser and shampoo, the grade can soften surfactant irritation while strengthening the broader preservation strategy.
- It is most effective in multi-component systems with 1,2-Hexanediol, Ethylhexylglycerin or Caprylhydroxamic Acid, followed by challenge testing.

Frequently asked questions
What is the cleanest way to compare Hydroxyacetophenone with the current booster?
Use matched bases with the same primary preservation components and change only the booster. Compare challenge-test performance, color, odor and sensory feel on the same schedule so a formulation difference is not mistaken for a booster effect.
How do you tell whether a Hydroxyacetophenone trial improved microbial protection or only oxidation stability?
Use separate endpoints. Run the microbial challenge test for preservation, and track color, odor and oxidation markers in the stability program; one result should not be used as proof of the other.
What should change first if a Hydroxyacetophenone system misses the fungal acceptance criterion?
Review the complementary preservation partner and the formula’s contamination risk before raising every component. Use a focused split-batch screen, then repeat the full challenge test with the best combination.
