BHT (Butylated Hydroxytoluene) from Bio Shop™ is a potent antioxidant used to stabilize oils, butters, and oil-based formulations like creams, serums, and perfumes. It prevents rancidity, extends shelf life, and protects sensitive ingredients from oxidative damage. Ideal for use in DIY beauty and perfume projects where long-lasting stability is required. Use at a low concentration of 0.01%–0.1%, and dissolve in oil phase before mixing. Not water-soluble. Always follow safe usage limits. BHT ensures your formulations stay fresh, effective, and long-lasting.
