How about Kao softener?
Kao softener, which is rich in floral fragrance, is said to be a rose flavor but not a rose flavor, much like the mixed flavor of many flowers, and I don't like this flavor on clothes either.
Is the fragrance of softener harmful to human body?
Softeners can make clothes soft, antistatic and smell clear, but any chemicals are harmful to people's health, only in size, so don't use them often. Clothing softener contains many dangerous chemical components, including benzyl acetate, benzyl alcohol, limonene and linalool. For children, the elderly and patients, long-term exposure to these chemicals is particularly dangerous.
Softener principle
Cationic surfactants are generally used as softeners to form hydrophobic films on the fiber surface. Because the softener is adsorbed on the fiber surface, the friction between fibers is reduced and the fibers are recovered, so the fabric becomes softer, fluffy and elastic. Cationic surfactants can also produce positive charges, because most clothes are negatively charged, which can play a certain anti-static role. Clothing softener takes cationic surfactant as the main raw material, which can make the fiber surface soft, smooth, antistatic and not easy to stick after washing.
