I am making a moisturizing lotion at pH 4.5. currently adjusting pH with citric acid.
i have made samples with using salicylic acid instead of citric acid to adjust pH. 0.4% salicylic acid is enough to adjust pH to 4.5.
I like the version with salicylic acid to provide that extra benefits of it too.
This Product will be applied to dry face, hand and feet of people at all ages.
My question is: is 0.4-0.5% salicylic acid in emulsion safe for babies?
If no then for above what age childs it is safe for?
