Liquid Ingredients FAQs

Do I need a CPSR when using liquid cosmetic ingredients?

If you are selling a finished cosmetic product, it must have a CPSR before it can be placed on the market.

Are all liquid cosmetic ingredients the same quality?

No. Ingredient quality and documentation can vary significantly between suppliers. Using poorly documented or inconsistent ingredients can lead to delays, changes in the performance of your product, or issues during the CPSR process.

Are your liquid ingredients supplied with documentation?

Yes, all ingredients are supplied with relevant documentation, including SDS and supporting information required for cosmetic safety assessments.

How do I choose the right liquid ingredient for my skincare products?

The right choice depends on your product type, target market, and formulation goals. For example, Phytokeratin is popular for haircare, while hydrosols for skincare are commonly used in toners and mists.

Can I mix different liquid ingredients together safely?

Yes, but compatibility and safety must be assessed. It is important to carry out your own small batch testing to confirm the stability and performance of your product, its suitability for the intended use of the finished product, and that the appearance aligns with your goals.
