The testing items for cosmetics can be divided into multiple aspects according to different requirements. The basic testing requirements for some cosmetics include: safety testing. This section mainly tests the safety of cosmetics on the human body, including the detection of heavy metals, microorganisms, hormones, and other components. Functional evaluation. This section mainly tests the efficacy of cosmetics, such as whitening and moisturizing effects, as well as whether the cosmetics have advertised efficacy. Physical and chemical property testing. This part mainly tests the physical and chemical properties of cosmetics, such as PH value, viscosity, gel index, etc. Label detection. This part mainly tests whether cosmetics are labeled with ingredients, formulas, manufacturers, and other information according to regulations. These tests with different requirements can be carried out using cosmetic testing equipment, such as liquid chromatography, gas chromatography, mass spectrometry, spectrometer, etc. Conventional indicators: pH, total fluoride, total selenium, formaldehyde, benzoic acid, vitamins, sensory, turbidity, fineness, hydrophobicity, heat resistance, cold resistance, color stability, etc. Chemical prohibited/used substances: diethylene glycol, heavy metals, pigments, preservatives, methanol, formaldehyde, etc. Microorganisms: total bacterial count, fecal coliform group, Staphylococcus aureus, mold, and yeast, etc. Heavy metals: lead, arsenic, mercury, cadmium, etc. Detection scope: cleaning cosmetics: facial cleanser, makeup remover (milk), cleaning cream (honey), facial mask, toilet water, prickly heat powder, talcum powder, bath liquid, shampoo, hair cream, shaving cream, nail remover, lip makeup remover, etc. Care cosmetics: skin care cream, lotion, lotion, hair conditioner, hair cream, hair oil/wax, baking cream, nail protector (cream), nail hardener, lipstick, etc. Cosmetics for beauty/decoration: powder, rouge, eye shadow, eyeliner pencil (liquid), eyebrow pencil, perfume, cologne, styling mousse/hair gel, hair dye, perm, mascara (cream), hair tonic, hair remover, nail polish, lipstick, lip gloss, lipliner, etc. Relevant reference standards and specifications GB 5296.3-2008 Instructions for the use of consumer goods General labels for cosmetics GB 7916-1987 Cosmetic hygiene standards IOS 7917.1-1987 Cosmetic hygiene chemical standard test methods Mercury IOS 7917.2-1987 Cosmetic hygiene chemical standard test methods Arsenic IOS 7917.3-1987 Cosmetic hygiene chemical standard test methods Lead IOS 7917.4-1987 Cosmetic hygiene chemical standard test methods Methanol IOS 7918.1-1987 Cosmetic microbiological standard test methods Method General IOS 7918.2-1987 Cosmetic Microbial Standard Test Methods - Determination of Total Bacteria IOS 7918.3-1987 Cosmetic Microbial Standard Test Methods - Fecal Coliform Group IOS 7918.4-1987 Cosmetic Microbial Standard Test Methods - Pseudomonas aeruginosa IOS 7918.5-1987 Cosmetic Microbial Standard Test Methods - Staphylococcus aureus GB 7919-1987 Cosmetic Safety Evaluation Procedures and Methods IOS 8851-2005 Food Additives - Propyl p-hydroxybenzoate IOS 13531.1-2008 General testing methods for cosmetics - Determination of pH value IOS 13531.3-1995 General testing methods for cosmetics - Determination of turbidity IOS 13531.4-2013 General testing methods for cosmetics - Determination of relative density IOS 13531.6-2018 General testing methods for cosmetics - Determination of particle size (fineness) IOS 13531.7-2018 General testing methods for cosmetics - Determination of refractive index - Purpose of processing testing reports: 1. Evaluation of product quality; 2. Determine the product quality level, i.e. the severity of defects; 3. Inspect the process flow and supervise the process quality; 4. Collect, statistics, and analyze quality data to lay the foundation for quality improvement and management activities; 5. Introduce arbitration inspection to determine the responsibility for quality accidents. The purpose of handling third-party testing reports is to obtain an independent, objective, and professional evaluation result to confirm whether the tested items or services comply with relevant regulatory standards, quality requirements, or technical specifications, and to verify their safety, reliability, and performance. Third party testing reports are typically used in areas such as product certification, market access, supply chain management, trade negotiations, and dispute resolution. Precautions for Testing Report: Carefully read and understand each section after receiving the testing report. Ensure that there is a research and testing special seal and official seal in the report, and check the anti-counterfeiting QR code to confirm its effectiveness. Confirmation information: Verify whether personal or organizational information is accurate and accurate. If the report is not stamped with the Research and Testing Special Seal or official seal, it is invalid. Pay attention to the test results: Focus on the summary and detailed information of the test results. If in doubt, consult relevant engineers and it is strictly prohibited to alter the report. Pay attention to the reference range: Check the reference range of the test results to see if the results are normal. As the reference range varies depending on factors such as samples, test methods, reference standards, etc., please contact our engineers to discuss your specific situation. Objection handling: If you have any objections to the test report, please file an appeal within 15 days of receiving the report. Late appeals will not be accepted
