4-Butylresorcinol is known as a potent, safe and cost effective brightening agent. Even though 4-Butylresorcinol is suitable for real efficacy and competitive cost, cosmetic formulators and manufacturers sometimes find it difficult to incorporate since it is a sticky powder difficult to solubilize. CARE ACTIV BRIGHT solves this issue. It is a liquid, made by combining the brightening efficacy of 4-Butylresorcinol and solvents widely used in personal care, as a real one-product solution.
