Plant extracts are widely used in skincare OEM production for their natural, mild, and effective properties, but their quality directly affects the safety and efficacy of final products. Purity indices and contamination control are two core focuses of plant extract testing in OEM production—purity determines the efficacy of the extract, while contamination control ensures product safety. Strict testing standards and scientific control measures are essential to select high-quality plant extracts and avoid potential risks. This article details the key purity indices and contamination control points of plant extract testing in skincare OEM, providing practical guidance for brands to ensure product quality and compliance.
Key Purity Indices of Plant Extract Testing in OEM
1. Active Ingredient Content
Active ingredient content is the core purity index of plant extracts, directly determining their efficacy in skincare products. OEM enterprises must test the content of target active ingredients (e.g., flavonoids in ginkgo extract, saponins in ginseng extract) using professional methods such as high-performance liquid chromatography (HPLC) or gas chromatography (GC). The content must meet the pre-agreed standards between the OEM and supplier—too low content will reduce product efficacy, while excessive content may increase skin irritation or violate regulatory requirements.
2. Impurity Content Control
Impurity content is another key indicator of plant extract purity, including water content, ash content, and insoluble matter. Water content should be strictly controlled (usually ≤10%) to avoid microbial growth and extract degradation during storage. Ash content reflects the content of inorganic impurities (e.g., soil, minerals) introduced during extraction, which should not exceed the specified limit to ensure product purity. Insoluble matter, such as unextracted plant fibers, should be filtered out to avoid affecting product texture and absorption.
Contamination Control in Plant Extract Testing
Plant extracts are prone to contamination during planting, extraction, and transportation, so contamination control is critical for product safety. First, microbial contamination control: test for total bacteria, mold, yeast, and pathogenic bacteria (e.g., Escherichia coli, Staphylococcus aureus) to ensure they meet cosmetic safety standards. Second, heavy metal contamination control: detect heavy metals such as lead, mercury, and arsenic (common in plants grown in polluted soil) using atomic absorption spectrometry, with content not exceeding global regulatory limits. Third, pesticide residue control: for artificially planted plants, test for pesticide residues (e.g., organophosphates, pyrethroids) to avoid potential skin irritation and health risks. MOOYAM OEM strictly adheres to ISO 22716 and GMP standards, establishes a strict plant extract testing system, strictly controls purity indices and contamination risks, provides one-stop OEM services, and helps brands select high-quality plant extracts and ensure product safety and efficacy.
