Stability of Proanthocyanidins in Grape Seed Extract Cream
Question
Is Proanthocyanidins (Grape Seed Extract) stable, especially when formulated into a cream? What factors influence its stability in a cream product?
Answer
# Stability of Proanthocyanidins in Grape Seed Extract
Thank you for your question regarding the stability of Proanthocyanidins in grape seed extract, especially when used in cosmetic formulations like creams.
Based on our information, Proanthocyanidins are considered to have high oxidative stability. This inherent stability applies to the substance itself, including when it is in the liquid extract form that we offer.
Regarding the stability when mixed into a cream formulation, while the Proanthocyanidins themselves are stable, the overall stability and shelf life of the final cream product are influenced by the complete formulation. Factors such as the presence of other ingredients, the pH of the cream, the manufacturing process, and importantly, the packaging used, all play a significant role.
To help ensure the longevity and stability of the active ingredients, including Proanthocyanidins, in your final cosmetic product, it is highly recommended to store the finished cream in packaging that provides good protection against light and heat. This practice helps to preserve the quality and efficacy of the formulation over time.
