CAS: 2163-42-0
Methylpropanediol (MDP) is a type of chemical compound that belongs to the diol family. This clear, low-molecular-weight liquid is very soluble in water and other organic solvents. Due to its distinct characteristics, MDP is used in a range of industries, especially personal care and pharmaceuticals. Compared to its similar counterparts, MDP is not just a great solvent, but also significantly promotes skin moisturizing which makes MDP as a wonderful ingredient for cosmetic products. MDP have been in use since 1950 for formulating stable and fast-absorption products
This compound mainly used for cosmetics is found in some cleaning solutions too, simply due to its great capability of dissolving oils and other residues.
