Adding Rose Extract for Fragrance and Odor Masking in Serum

Question

I have a serum formulation containing various ingredients, including Bifida Ferment Lysate, beta glucan, Prebio-care, PiteraEx, Snow Mushroom Hyaluron, Allantoin, 4D Hyaluronic Acid, Lactobacillus Ferment, Rosa Hybrid Cell Extract, Apple Stem Cell Extract powder, Matrixyl 3000, Adenosine, CICA, Madecassoside, dl-alpha tocopherol, Tocotrienols, Squalane, Phospholipid, Ethoxydiglycol, Skin-Barrier, Mild Preserved Eco, Satin Cream Maker, and Water. The formula currently has a slight odor from the ingredients. I want to add Rose (Rosa Damascena) Extract Mon rose extract to mask these odors and give the formula a light, non-pungent rose scent. What is the recommended usage percentage for the rose extract?

Adding Rose Fragrance to Your Formula

To add a light rose fragrance and help mask the scent of other ingredients in your formula using Rose (Rosa Damascena) Extract Mon rose extract, the recommended usage rate is 0.5% to 5%.

This extract is designed primarily for fragrance and marketing purposes, focusing on providing a natural scent. It should be added to the water phase of your formulation.

Recommendation:

Start by adding the extract at a lower percentage, such as 0.5% or 1%. Mix thoroughly and evaluate the scent. If the existing odors are not sufficiently masked or you desire a stronger rose scent, gradually increase the percentage within the recommended range (up to 5%). Testing is key to finding the perfect balance for your specific formula.

Ensure your final product's pH is between 3.5 and 7, as recommended for this extract.
