Plasticizers are multifunctional ingredients added to formulations to enhance flexibility, consistency, softness, spreadability and stability. They improve the texture, durability and ease of application of products such as nail polishes, hair sprays, lotions, and shampoos by making them less brittle and more flexible.
Common Plasticizers: Phthalates such as diethyl phthalate (DEP), dibutyl phthalate (DBP), and dimethyl phthalate (DMP), Citrate esters such as acetyl tributyl citrate and acetyl triethyl citrate, Glycerin & Propylene Glycol, Silicones (Dimethicone, Cyclopentasiloxane), Castor Oil & Esters
Phthalates, once widely used, have raised concerns over potential health effects, leading to their reduced use in cosmetics
