What Are The Main Aspects Of Quality And Safety Risks Of Plant Raw Materials?

Apr 11, 2022

The quality and safety risks of plant raw materials mainly focus on heavy metals, pesticide residues, solvent residues, and the content of characteristic / effective components. At present, the published raw material standards basically cover physical and chemical indicators, health indicators, identification / content determination of characteristic / effective components, and other items.

As an example, the extract of Centella Asiatica, the raw material used in cosmetics, Centella Asiatica is mostly used in cosmetics such as whitening and freckling, anti-wrinkling, and expectorant, and the standard sets such indicators and limits for heavy metal elements (mercury, lead, arsenic, and cadmium), microbial indicators (total number of colonies, total number of molds and yeasts, heat-resistant Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa) to ensure the safe use of raw materials; For its main efficacy component, Asiatic total glucoside (in terms of the sum of Asiatic, hydroxyasiatic), The content determination method and limits (≥ 2.5 mg/ml) were specified in the standards to ensure the consistency, stability, and efficacy of the starting materials. The implementation of this standard preliminarily solves the problem of the uneven quality and poor quality raw materials of Centella Asiatica extract occupying the market at a low price, which provides technical support for the quality control of Centella Asiatica extract raw material supply, use, and so on, and helps to guarantee the related product quality safety and efficacy.
