Our take
Is Tetra-Di-T-Butyl Hydroxyhydrocinnamate a Good Ingredient?
This one rates Good as an effective, stable oil-phase antioxidant that prevents rancidity and color drift at very low use levels, with a low irritation profile. Its job is protecting the formula rather than acting on skin directly, which caps it below Great despite the reliable performance.
What it does
Skin Benefits
Helps products keep their intended smell and appearance by slowing the breakdown of delicate oils, reducing the chance of rancid odors and off-colors over time.
Where you'll find it
Uses in Skincare & Cosmetics
Frequently added to facial oils, sunscreens, and oil-rich serums to improve shelf stability, and also used in lipsticks and balms to maintain formula integrity.
Before you use it
Safety
Generally low risk at typical cosmetic concentrations and not commonly irritating. As with most antioxidants, avoid direct eye contact and discontinue use if sensitivity appears. No widely recognized cosmetic-specific restrictions apply when it's used as intended.
