DIMETHYL PHTHALATE
Dimethyl Phthalate (DMP)
Safety grade: C
Dimethyl phthalate is a clear, colorless liquid chemical used in cosmetics and personal care products. It helps products spread smoothly, keeps them from drying out too quickly, and allows nail polish and other formulas to form an even coating.
This ingredient acts as a plasticizer and solvent that improves product texture, helps create a smooth film on skin or nails, and masks unpleasant odors while allowing other ingredients to dissolve properly.
