Exfoliating Essence Formulation: Papain Alternative and Formulation Details

Based on the previous discussion and your interest in adding exfoliation to your essence formula:

• Regarding Papaya Enzyme (Papain): As the staff mentioned, Papain (ID 1036) is not ideal for this type of water-based essence formula because it is unstable in water and loses its effectiveness over time, especially with heat. It's best suited for dry powder formulations.
• Recommended Exfoliant: The staff recommended using Complex Salicylic Acid (Powder, Water-Soluble) (ID 2014) at a concentration of 1-2% as a suitable alternative for adding exfoliation properties to your essence.
• Mixing Order: While a specific step-by-step mixing order for all ingredients wasn't provided, generally, you would dissolve your water-soluble ingredients into the base (Galactomyces Ferment Filtrate).
• Calculation: As confirmed by the staff, calculations for your 50g product should be done by weight (grams), not volume (ml). For example, 1% of 50g is 0.5g.
• Preservative: Using Galactomyces Ferment Filtrate (ID 357) as the base at over 70% means you do not need to add an additional preservative, as it already contains one from the manufacturer.
• Texture: Be aware that with the combination of active ingredients, particularly DMAE (ID 637), the resulting essence may have a sticky texture.
