What is the difference between these two? Most always customers request SDS (MSDS) sheets versus a Certificate of Analysis Sheets. So what is the difference between these two?
A safety data sheet (SDS), material safety data sheet (MSDS), or product safety data sheet (PSDS) is an important component of product stewardship and occupational safety and health. It is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. SDS formats can vary from source to source within a country depending on national requirements.
A Certificate of Analysis is a document issued by Quality Assurance that confirms that a regulated product meets its product specification. They commonly contain the actual results obtained from testing performed as part of quality control of an individual batch of a product. For Pigments is will contain the Batch # of that pigment and the results of the testing along with the heavy metal content of that batch and whether it meets the requirments needed for cosmetic use. These requirments in the US are dictated by the FDA. It will also give you the breakdown of that pigment. In the case of Mica Powder it will give the % of each component (Mica, Titanium and Pigments) plus the micron size. This should not vary much between batches. If said the color does not comply with the CI # it may be sold as “off spec”. It will still be safe but the color may vary from what is the standard of the color.
