Formulation with Double Hyaluron Liquid, LHA, and Extracts: Preservatives and pH

Question

I would like to create a formulation using Double Hyaluron Liquid, LHA (Capryloyl Salicylic Acid), Aloe Vera Extract, Green Tea Extract, and Glycerin. Does Double Hyaluron Liquid contain a preservative, and if so, how should I adjust the preservative amount in the final formula? Is this combination of ingredients compatible, and are there any specific considerations, such as pH levels, when mixing them?

Answer to Your Formulation Questions

Regarding your questions about formulating with Double Hyaluron Liquid:

Does Double Hyaluron Liquid contain a preservative?
Yes, Double Hyaluron Liquid contains a preservative. However, when incorporating it into a formulation, you should still add a preservative to the overall formula. You can adjust the amount of additional preservative needed based on the percentage of Double Hyaluron Liquid used in the formula.
Can Double Hyaluron Liquid, LHA, Aloe extract, green tea extract, and glycerin be mixed together?
Yes, you can create a formula using Double Hyaluron Liquid, LHA (Capryloyl Salicylic Acid), Aloe Vera Extract, Green Tea Extract, and Glycerin. However, it is important to control the pH of the final mixture. LHA is acidic and can lower the pH, which might cause natural extracts like Green Tea Extract to degrade if the pH drops below 4.0. You can adjust the pH upwards by adding a base such as Triethanolamine.
