At present, the typical deodorant uses up to 80% ethanol or propylene glycol, or a combination of both, its components have many shortcomings, ethanol has a drying effect on the skin, but can cause different degrees of irritation, propylene glycol on the skin will also produce irritation or allergy, especially when the concentration of more than 10% in the formula is even more so, and liquid silicone is basically non-toxic. It also does not sting on injured or worn skin. Therefore, the deodorant made of silicone oil and cyclic siloxane substances can overcome the above characteristics, and improve the lubricity of the preparation, so that the deodorant is particularly soft, and the production of apocrine components of the human body is controlled, so as to achieve the purpose of deodorization. Polydimethylsiloxane polyol copolymers can improve the compatibility of many common deodorant raw materials with other ingredients.
