Waterproof, Alcohol-Based Makeup Formulation with Mica
คำถาม
I am formulating a waterproof makeup product using a 99% alcohol base with mica as the pigment. Can I use WetGuard as the polymer base? What kind of binder is needed for mica and the polymer in this system, considering glycerin is water-soluble? Do you have alternative suggestions for the polymer base, binder, and pigment suitable for a waterproof, alcohol-based formula applied with a brush?

Waterproof, Alcohol-Based Makeup Formulation with Mica
Regarding your questions about formulating a waterproof, alcohol-based makeup product with mica:
Using WetGuard as a polymer base: The product "WetGuard" was not found in our database, so we cannot confirm its suitability. For a 99% alcohol base, the polymer must be soluble or dispersible in high-concentration alcohol.
Binder for mica and polymer: Glycerin is water-soluble and not suitable for a 99% alcohol system. You need a binder/dispersant compatible with solvents. The polymer acts as the main film-former after alcohol evaporation.
Alternative solutions:
- Polymer Base: Consider using a polymer specifically designed for solvent systems, such as PVM/MA Copolymer (Solvent Soluble). This type of polymer is soluble in solvents like Acetone and forms a waterproof film.
- Binder/Dispersant: To disperse mica and prevent settling in an alcohol base, use a solvent-borne dispersant like BYK 185 (Dispersing for solvent-borne additive).
- Pigment: Mica Powder is suitable. You can choose different types, such as Mica Powder (Silane Coated) for better feel and dispersion or Silver Sparkle Mica for shimmer.
In conclusion, for a waterproof, alcohol-based makeup, choose a solvent-soluble polymer, a solvent-borne dispersant for the mica, and the appropriate mica type. Glycerin is not suitable.
