with cosmetics OEM the rapid development of the industry, so cosmetics OEM manufacturers have also become the preferred partner of many brand owners. however, due to the current chaotic cosmetic raw material market, inappropriate additions are emerging one after another, resulting in risky substances being carried into the finished product. in addition, the national supervision is getting stronger and stronger. if cosmetics are OEM The manufacturer does not have good raw material control measures, which will cause the brand to be exposed to unknown risks at any time. Therefore, not only to better protect the rights and interests of the OEM, but also to ensure the quality of the OEM products, so for customers who bring their own raw materials for processing, cosmetics OEM Manufacturers should pay attention to the following aspects.

First, customers must provide samples of their own materials, and provide detailed introduction information, storage conditions instructions, MSDS、 Ingredient composition and proportion, preservatives, COA、 Precautions, place of origin, compliance and stability statement (official seal required) and relevant test reports (such as hormone test reports, heavy metal test reports, and other related test reports, etc.)； This ensures that cosmetic raw materials comply with relevant national regulations and ensures product quality and safety from the source.

Secondly, after customers provide their own materials to cosmetics OEM manufacturers, the manufacturer's laboratory should conduct risk screening, and only after passing the screening can they enter the testing and formula design stages. The cost of risk screening is generally borne by the customer (Also negotiable )，Ingredients that fail the screening cannot be used for testing or formula design.；

The last step is to prepare self-bred materials for large-scale production. The first batch of incoming materials should be sampled for risk screening to ensure the quality of raw materials used to produce finished products. Raw materials that fail the screening must not be used in production ； If there are many batches of self-produced materials, random inspections will be carried out according to the annual inspection plan formulated by the processing manufacturer to ensure stable quality. ； In addition, the brand owner needs to provide an authoritative third-party test report once every year for the self-brought materials. ；

The above are examples of cosmetics that bring their own raw materials OEM Manufacturers need to pay attention to matters. Only by doing these well can the quality and safety of OEM products be guaranteed.
