Antioxidants
ANTIOXIDANTS
An antioxidant in a cosmetic product helps protect the formula and the skin from damage caused by free radicals, which are unstable molecules generated by factors like air exposure, light, and pollution.
In formulations, antioxidants:
Slow oxidation of oils and actives, helping prevent rancidity and extending shelf life
Support skin health by helping defend against environmental stressors
Maintain product performance and appearance over time
Common cosmetic antioxidants include vitamin E (tocopherol), vitamin C derivatives, rosemary extract, and botanical polyphenols. Used at low levels, they play a key role in keeping products stable, effective, and skin-friendly.

Antioxidants
Antioxidants are functional cosmetic ingredients used to protect both the formula and the skin from damage caused by oxidation. In cosmetic chemistry, they work by neutralizing free radicals that can degrade oils, fragrances, and sensitive actives, helping maintain product quality, appearance, and performance over time.
Why Antioxidants Are Used in Cosmetics
- Prevent oxidation and rancidity of oils and butters
- Extend shelf life and improve formulation stability
- Support skin protection against environmental stressors
- Preserve color, odor, and efficacy of finished products
Antioxidants are especially important in products containing unsaturated oils, botanical extracts, essential oils, or vitamins.
Typical Usage Levels
Usage depends on the antioxidant type and the formulation:
- Vitamin E (Tocopherol): 0.05–1.0%
- Rosemary Extract (oil-soluble): 0.02–0.2%
- Ascorbyl Palmitate: 0.05–0.5%
- Green Tea Extract: 0.1–2.0% (water-based systems)
Antioxidants are often added during the cool-down phase to preserve their activity.
Common Antioxidant Examples
- Tocopherols (Vitamin E) – oil-soluble, widely used for oil protection
- Ascorbyl Palmitate – fat-soluble vitamin C derivative
- Rosemary Oleoresin Extract (ROE) – natural oil stabilizer
- Green Tea, Grape Seed, or Pomegranate Extracts – polyphenol-rich botanicals
- Ferulic Acid – often paired with vitamins C and E for synergistic effects
