Introduction
The test substance is of this standard "Hygienic Standard for Cosmetics" provides eye care cosmetics banned substances may not be as eye
Cosmetics raw materials, component Add to eye care cosmetics. If technically unavoidable banned substances into the eye makeup when,
The finished cosmetic products should meet the "Hygienic Standard for Cosmetics" General requirements for eye makeup, that is normal and reasonably foreseeable conditions of use
Lower member can not cause harm to human health.
At present, China has not yet specified the substance of limited value, the present standards, measuring only eye care cosmetics provide these materials seized
Measuring method.
