What is Bht used for?
BHT (aka Butylated hydroxytoluene) is commonly found in skincare formulations where it is added as an anti-oxidant. Butylated hydroxytoluene (BHT) inhibits autoxidation of unsaturated organic compounds. BHT is used in food, cosmetics, and industrial fluids to prevent oxidation and free radical formation. It is often added to skin care formulations to protect the other active ingredients from oxidative attack and resulting degradation.

What we know about using Bht while pregnant or breastfeeding
Limited information available.
BHT was found to cause effects to the liver and kidneys when taken orally at large doses. This is where the link between BHT and hormone disruption is generally made. However, the Expert Panel argued that this is outside the scope of BHT used in skincare, as the concentrations used in skincare usually range between 0.01 and 0.1%. The FDA considers BHT as Generally Recognized As Safe (GRAS) to use as a food additive up to concentrations of 0.02%. BHT is also not well absorbed through the skin, further mitigating this risk of hormone disruption.
