Imidazolidinyl urea is a preservative in cosmetics. It has broad-spectrum antibacterial activity and can inhibit Gram-negative and positive bacteria. It has a certain inhibitory effect on yeast and mold. It is mainly used to inhibit the reproduction of microorganisms. Various components in cosmetics are compatible, and the test results show that its antibacterial ability is not affected by surfactants, proteins and other special additives in cosmetics. Application: Imidazolidinyl urea can be used in creams, shampoos, lotions, conditioners and other products. It can be used alone or in combination with parabens and IPBC to enhance its antiseptic effect. The pH value range is 3~9, the general addition amount is 0.2~0.4%, and the maximum allowable addition amount is 0.6%. It can be added in a wide temperature range (<90℃). Usually imidazolidinyl ureas are combined with parabens or caesone CG as cosmetic preservatives. It can be used in creams, lotions, shampoos, etc. It is especially suitable for some advanced nutritional cosmetics that are easy to be infected with P. aeruginosa when the pH value is alkaline. The usual dosage is 0.1% to 0.5%. However, because imidazolidinyl urea has a stimulating effect on the skin of some people and is easy to cause allergies, it is no longer used in some high-end cosmetics.
