A safety data sheet (SDS), material safety data sheet (MSDS), or product safety data sheet (PSDS) is an important component of product stewardship, occupational safety and health, and spill-handling procedures. SDS formats can vary from source to source within a country depending on national requirements. "Wikipedia"
NOTE* SDS are written for manufacturing and production industry standards and as such, usually refer to vast quantities of a product in a raw (pre being made into a product) state. Reading finished product labels is also an important step to ensure best handling practices.
