15 | Staphylococcus Aureus Test | This method specifies the testing method for Staphylococcus aureus in toothpaste. |
16 | Molds and Yeasts Count | This method specifies the testing method for molds and yeasts count in toothpaste. |
2 Testing Methods for Cosmetic Ingredients
No. | Introduction | |
1 | Determination of Dioxane in Cosmetics | This method specifies the gas chromatography-mass spectrometry method for the determination of dioxane content in cosmetics. It is suitable for the determination of dioxane content in liquid water-based, creams and lotions, gels, powders, and cleansing oil cosmetics. |
2 | Determination of Dimetridazole and Other 119 Kinds of Components in Cosmetics | This method specifies the liquid chromatography-mass spectrometry method for Dimetridazole and other 119 kinds of components in cosmetics, including qualitative screening methods and quantitative determination methods. It is suitable for the qualitative screening and quantitative determination of 120 ingredients such as dimethonidazole in liquids, creams and lotions, gels, powders, wax-based and oil-based cosmetics. |
2 Methods for Toxicological Test
It's noteworthy that the current Safety and Technical Standards for Cosmetics (STSC) lack a dedicated chapter on the pretreatment of toxicological test samples for cosmetic ingredients and products, with no relevant content on acute inhalation toxicity tests. The introduction of the following two standards aims to complement and improve the current STSC.
No. | Introduction | |
1 | Technical Requirements for Pretreatment of Cosmetic Materials and Products in Toxicological Experiments | This standard specifies the basic principles, requirements, and methods for toxicological test sample’s pretreatment, and is applicable to toxicological testing of cosmetic ingredients and products. |
2 | Acute Inhalation Toxicity Study | This standard specifies the basic principles, requirements, and methods for acute inhalation toxicity testing of animals, and is applicable to the toxicology test for the safety of cosmetic ingredients. |
