Ingredient Compatibility with Silky Serum Base

Based on the properties of the ingredients and the Silky Serum Base, the following can be used together:

• Licorice Extract (Licochalcone A 1%, Water-Soluble): This extract is water-soluble and compatible with the Silky Serum Base, which is designed for water-soluble ingredients. Ensure the final serum pH is within the recommended range for the extract (3.5-6.5).
• Centella Asiatica Extract (Madecassoside 90%): This powder extract is water-soluble (up to 1.0%) and can be dispersed in the base. It should be added in the final mixing step and avoid heat. The recommended pH range for the extract (4-6.5) is compatible.
• Silybum Marianum Fruit Extract (Water Soluble Powder): This extract is water-soluble and can be mixed into the base. It should be added to the water phase and avoid heat.
• Mild Preserved Eco™ (Preservative-Free): This ingredient is soluble in water with blending and works within a pH range of 4-9, which is compatible with typical serum formulations. It should be added in the final step.

All these ingredients are compatible with the water-based nature of the Silky Serum Base and their recommended usage guidelines align with creating a serum.

Mixing Tool

A milk frother is not suitable for mixing cosmetic ingredients into a serum base. It is designed to create foam, not to provide the necessary shear force to properly incorporate ingredients into the base. As advised, a hand blender with an appropriate head can be used as an alternative kitchen tool for mixing.
