Centella Extract (Madecassoside) and Skin Absorption
Question
Based on the information that some terpenes/terpenoids can act as skin penetration enhancers, I would like to clarify: Does Centella Asiatica Extract (specifically Madecassoside, which is a terpenoid) reduce the absorption of oil-soluble substances in a cosmetic formulation?
Answer
Regarding your question about whether Centella Extract (specifically Madecassoside, which is a triterpenoid) reduces the absorption of oil-soluble substances in your formula:
According to the staff's response, while Madecassoside is indeed a terpenoid, there is no information available to suggest that Madecassoside acts as a penetration enhancer or that it would reduce the absorption of oil-soluble substances.
Therefore, based on the information provided, Centella Extract is not expected to reduce the absorption of oil-soluble substances in your formulation.
