Deodorant cosmetics belong to special-purpose cosmetics, while antiperspirant cosmetics do not have a clear attribution.
If the deodorant function is declared at the same time, it is managed as a deodorant special-purpose cosmetic. If only the antiperspirant effect is declared, such as talcum powder, it can be managed as a non-special-purpose cosmetic.
Deodorant cosmetics not only reduce sweat secretion like antiperspirant cosmetics, but also can destroy the intermediate products of sweat, inhibit bacterial reproduction, and achieve the purpose of removing sweat odor.
Only claiming antiperspirant effect, such as talcum powder, can be managed as a non-special use cosmetic.
Since deodorant cosmetics have the dual functions of deodorization and antiperspirant, their main components include antiperspirant (or astringent) as well as bactericides and deodorants. Several components are often used in combination in deodorant cosmetics. .
The antiperspirant has a strong astringent effect to inhibit the excessive discharge of sweat, which can play an indirect deodorant effect.
Common antiperspirants are zirconium hydroxychloride aluminum complex, zirconium hydroxychloride aluminum glycine complex, zinc hydroxychloride, zinc sulfate, zinc p-hydroxybenzenesulfonate, aluminum chloride, basic aluminum chloride, aluminum sulfate , aluminum potassium sulfate (alum) and other various aluminum and zinc salts.
Among them, zirconium hydroxyaluminum chloride is more commonly used, which can be micronized to increase its contact area with the skin, and then compounded in deodorant products.
Bactericides are used to inhibit or kill bacteria parasitic on the skin such as armpits to achieve the purpose of deodorization and deodorization.
Commonly used fungicides include boric acid, chlorhexidine acetate, benzalkonium chloride, etc., which are all restricted components or permitted preservatives included in the “Safety Technical Specification for Cosmetics”.
The deodorant can react with the lower fatty acids produced in the armpit to eliminate the odor and achieve the purpose of deodorization.
Commonly used deodorants are zinc oxide and certain alkaline zinc salts.
