BHT

BHT (Butylated Hydroxytoluene)

Effective antioxidant for protecting oils and formulations from oxidation, rancidity, and color or odor degradation.

INCI: BHT.

Appearance: White crystalline powder.

Solubility: Oil-soluble.

Typical Use Level: 0.01–0.1%.

Role in Formulas: BHT is a widely used antioxidant that helps prevent oxidation of oils, lipids, and sensitive ingredients. It protects formulations from rancidity, color shifts, and off-odors, improving product stability and shelf life.

What It Does

BHT is a powerful formulation stabilizer designed to protect oils and active ingredients from oxidative degradation.

It works by interrupting free radical chain reactions that lead to rancidity and breakdown of oils. This helps maintain the color, scent, and performance of finished products over time.

Key Benefits

• Helps prevent oxidation and rancidity in oils and emulsions.
• Maintains product color, odor, and stability.
• Extends shelf life of oil-based and hybrid formulations.
• Effective at very low concentrations.
• Supports stability of sensitive actives.

Suggested Use Levels

• 0.01–0.05% in standard oil phases.
• 0.05–0.1% in highly oxidation-prone systems.

Ideal Applications

• Facial oils and serums
• Anhydrous formulations
• Emulsions with sensitive oils
• Vitamin-rich or active-heavy systems
• Fragrance and flavor oil stabilization

Formulation Notes

• Add to the oil phase and ensure full dissolution.
• Works best in combination with other antioxidants such as tocopherol.
• Effective at very low levels; avoid overuse.
• Helps protect both base oils and active ingredients.

BHT is used as a formulation stabilizer, not as a primary skin treatment active.
