Questions about Whitening Essence Formula: Solvent, Emulsifier, and Adjustments

Question

Regarding my proposed whitening essence formula, I have the following questions: Can 1,2-Hexanediol be used as a solvent for TXC instead of Glycol in the formula? Is using 2% Phospholipid as an Emulsifier to bind water and oil together sufficient? Based on this formula, are there any other necessary adjustments or advice you can provide?

Regarding your proposed whitening essence formula:

Using 1,2-Hexanediol as a solvent for TXC: Based on the information available, we cannot confirm if 1,2-Hexanediol can effectively dissolve TXC. Further testing or information specific to TXC's solubility in 1,2-Hexanediol would be needed.
Phospholipid as an Emulsifier: 2% Phospholipid is generally not sufficient to act as the sole emulsifier in a formula. As noted in the product description, it functions better as a co-emulsifier alongside a primary emulsifier.
- Alternative Emulsifier: If you are comfortable using heat in your process, Butter Cream Maker at approximately 3% is recommended as a suitable primary emulsifier.
- Determining Emulsifier Quantity: To simplify the process and avoid complex HLB calculations, it is recommended to use a 'cream maker' type emulsifier, which is designed to create stable emulsions without requiring precise HLB matching.
Other Adjustments: Your formula incorporates several active ingredients and involves steps like using heat for dissolving certain components. This can make the formulation process quite challenging, especially for beginners. We recommend starting with simpler formulas if you are new to cosmetic formulation before attempting complex ones like this.
