Adding Glutathione Powder to Soap Base: Stability and Efficacy
Question
I want to add 5g of powdered Glutathione to 1000g of soap base. Is this amount suitable, and at what stage of the soap-making process should I add it to ensure it works effectively?
Answer
Regarding your question about adding glutathione to your soap base, based on scientific understanding, glutathione is highly unstable in the alkaline environment of soap. The high pH will cause it to degrade quickly, meaning it will not provide the benefits you might expect.
Therefore, adding 5g of powdered glutathione to 1000g of soap base, or any amount, is not recommended as it will likely become ineffective. Your questions about the specific amount and when to add it during the soap-making process are unfortunately not relevant because the ingredient itself is not stable in soap.
It's best to save your glutathione for applications where its stability can be maintained, as adding it to soap will likely result in it degrading and being ineffective.
