Question
What is the correct method to mix Sym-White (Phenylethyl Resorcinol) powder into a cream formulation containing an oil phase to achieve the best whitening results? Specifically, should it be pre-dissolved in oil first, or added directly to the cream in the final step? Can heat (up to 50°C) be used to aid dissolution?
Answer
Based on the provided information regarding Sym White (Phenylethyl Resorcinol):
- Dissolving in oil: Dissolving Sym White in oil before adding it to the cream is not recommended and is stated to be less effective than the suggested method. While the final cream formula needs to contain an oil phase, dissolving Sym White in oil alone first may not result in complete dissolution or optimal performance.
- Adding to the cream: The recommended method is to add Sym White directly into the finished cream base during the final step of the formulation process.
- Form: It is added as a powder directly into the cream.
- Assisting dissolution: You can use heat up to 50°C to help Sym White dissolve more quickly and completely into the cream base.
- Water solubility: The provided text does not mention that Sym White is soluble in water. It emphasizes adding it to a cream that contains an oil phase.
In summary, add Sym White powder directly to your finished cream in the final step, ensuring the cream has an oil phase, and mix well, using gentle heat (up to 50°C) if needed to aid dissolution. Avoid pre-dissolving it in oil separately.
