Practical formulation guide
Usage level: Suggested usage level: 0.1–10 % depending on the desired shade
Work in small increments according to tinting strength and observe the regulatory restrictions for the specific colorant.
How to use and incorporate: Micas and pigments (insoluble): first disperse in oil, glycerin or a small portion of the base until lump-free, then incorporate. In glycerin soap, disperse in alcohol or glycerin before adding to the melted base. Water-soluble colorants: prepare a 1 % stock solution in water and add drop by drop.
Formulation tips: Pre-disperse in a portion of the oil phase or in a high-polarity emollient to prevent color specks.
- Micas, pigments and glitter may migrate or settle in clear bases; use a more viscous base or suspending agents.
- Check that the colorant is permitted for the area of use (eye area, lips) under the regulations of the country of sale.
- Test first on a small sample: the final shade changes with the base, pH and light.
Compatibility: Micas and pigments are compatible with oils, waxes, powders and soap bases; water-soluble colorants with gels, shampoos and liquid soaps.
Storage: Cool, dry place, protected from light and moisture. Cosmetic grade / raw material for formulation.
Precautions: Avoid inhaling the powder (wear a dust mask). Craft glitters and pigments are not suitable for application on skin.
