Cosmetics and personal care chemicals and ingredients

Formulators usually search by INCI name or function rather than by CAS number, because one INCI name can cover products from many manufacturers. A cetearyl alcohol from one supplier may differ from another in the ratio of cetyl to stearyl alcohol, in physical form or in its palm or coconut origin, so compare grade details and request samples before switching.

Regulation decides what can be used and how much. The EU Cosmetics Regulation lists prohibited substances and restricted preservatives, colorants and UV filters in its annexes, the US regulates sunscreens as drugs, and China, India, ASEAN countries and others have their own ingredient lists and registration steps. Brands also respond to consumer demand for natural, vegan, sustainably sourced and microplastic-free ingredients. When you post a request, give the INCI name, the grade, the documents you need, such as the technical data sheet, safety data sheet, allergen and impurity statements and certifications, and the quantity, so suppliers can respond with the right offer.
