Frequently asked questions
What is BHA used for in cosmetics?
BHA is primarily used as an antioxidant and preservative in cosmetic formulations. It prevents oils and fats from going rancid, which helps to maintain the product's integrity and extend its shelf life.
Is BHA safe to use in skincare products?
Regulatory bodies generally consider BHA safe for use in cosmetics at low concentrations. However, some studies suggest potential concerns regarding its endocrine-disrupting properties and possible carcinogenicity at higher doses, leading to ongoing debate and restrictions in some regions.
