Cyclic Volatile Methyl Siloxanes (cVMS) Standards

Cyclic volatile methylsiloxanes (cVMS) such as D4, D5, and D6 are silicone-based compounds used in products like sunscreen, lotion, hair-care, and various industrial applications. ECHA has classified them as very persistent and bioaccumulative, raising environmental concerns. Regulations such as EU 2024/1328 have been introduced to restrict their use in consumer and professional products.
