Technical Information and Formulation Guidelines for Bakuchiol

Bakuchiol is a plant-derived alternative to Retinol, offering similar anti-aging benefits with significantly less irritation.

Product Form

Bakuchiol is typically supplied as a high-purity (99%+) oil-soluble liquid. It is easily incorporated into the oil phase of emulsions or anhydrous oil-based formulations.

Stability and Heat Resistance

• Heat Stability: It is relatively stable to heat and can withstand temperatures up to 75-80°C for short periods during the emulsification process. However, for optimal stability, adding it during the cool-down phase (below 40°C) is recommended.
• pH Stability: It remains stable across a broad pH range, typically between 3.0 and 6.5.
• Light Sensitivity: While more photo-stable than Retinol, it is still advisable to use UV-protected packaging (amber or opaque bottles) to maintain long-term efficacy.

Incompatibilities

• Strong Oxidizing Agents: These can cause the degradation of Bakuchiol.
• Metal Ions: Bakuchiol can be sensitive to metal ions (like iron or copper), which may lead to discoloration of the formula. It is recommended to include a chelating agent (e.g., Disodium EDTA) in the water phase.

Formulation Tips

• Antioxidant Support: Incorporating an antioxidant like Vitamin E (Tocopherol) helps protect Bakuchiol from oxidation and extends the shelf life of the product.
• Usage Level: The recommended usage rate is generally between 0.5% and 1.0%.
• Synergy: It pairs well with other anti-aging ingredients like Peptides and Vitamin C derivatives (depending on the specific derivative's pH requirements).
