T/GDCQMA 002-2023 Cosmetic stability testing specifications
Basic Information
Scope
Scope: This document specifies the requirements, methods, evaluation, and application of stability tests for cosmetics (including new raw materials and products). This document applies to cosmetics that undergo testing through certain procedures to examine the stability of sensory, chemical, physical, and microbiological changes in the samples and evaluate the results. Main Technical Content: I. Basic Requirements 1. Test Purpose: To examine the degree and patterns of sensory, chemical, physical, and biological changes in the samples under different environmental conditions (such as temperature, relative humidity, etc.) over time, and thereby determine the stability of the product packaging and storage conditions within the shelf life. 2. Test Design Principles: The test design should focus on product characteristics and emphasize sensory indicators. Accelerated stability test methods simulating transportation and usage processes can be used to investigate factors that may affect quality due to possible secondary contamination or reduced efficacy of preservative systems. 3. Test Item Selection Principles: The stability test items for cosmetics should be targeted and specific, including: a) New raw material stability tests: Attention should be paid to items that are prone to changes and affect quality safety during storage, including but not limited to observing the changes in the raw material properties (color, odor, etc.), physical and chemical properties, and ingredient content under the influence of temperature, humidity, and light. Destructive tests, i.e., stability test data under high-temperature (e.g., 60°C), low-temperature (e.g., -20°C), high-humidity (e.g., 90% RH ± 5% RH), or strong light storage conditions, can be selected based on the characteristics of the raw materials and the specific parameter setting conditions. b) Product stability tests: In addition to evaluating changes in sensory, physical, and microbiological indicators of the
