Are your pigments stable in high or low pH applications?
The stability & nature of our products may be altered depending on storage conditions, or when used in combination with other ingredients. This is beyond our control and we strongly recommend lab tests prior to commercial runs. Just Pigments cannot accept any liability in this regard. ALWAYS HAVE TEST RUNS BEFORE USING ANY OF OUR PIGMENTS FOR COMMERCIAL RUNS.
Most of our pigments are soap stable colors may morph depending on additives such as fragrances. Chemicals do react with some pigments so testing pigments first is the customer's responsibility. Business owners should be conducting tests, keep batch notes with results and run trials before any commercial release of a new product to the pubic. This is all part of BEST MANUFACTURING PROCESS.
Quality control is an essential part of GMP. It provides assurance that cosmetic products will be of consistent quality appropriate to their intended use.

It also includes where applicable, environmental monitoring programs, review of batch documentation, sample retention program, stability studies and maintaining correct specifications of materials and products.
7.2.1 The methods of reprocessing should be evaluated to ensure that they do not affect the quality of the product.
- Additional testing of any finished product which has been reprocessed should be performed.
