D1021 is a high-efficiency bis-quaternary ammonium cationic conditioning & antibacterial agent, belonging to dialkyl dimethyl ammonium chloride derivative. It is specially developed for personal care and daily chemical products, combining excellent softening, anti-static, moisturizing and broad-spectrum bactericidal performance. It can rapidly adsorb on hair and skin surface to form a smooth, non-greasy breathable protective film, effectively improving hair dryness, frizz and tangling, while inhibiting harmful bacteria growth. It has good compatibility and stable formula performance, being a multifunctional additive widely used in hair care, skin care and antibacterial cleansing products.
