Expert Verdict
Leading volatile linear silicone replacement for D5 (cyclopentasiloxane) following EU Reg 2024/1328 enforcement in June 2026. MW 335, bp 263°C, log P = 9 with excellent cosmetic volatile carrier properties without the vPvB environmental classification of cyclic siloxanes. Non-mutagenic, low acute toxicity (LD50 >2,000 mg/kg). Dermal penetration unlikely. Widely adopted in reformulated hair care and skin care as the primary cyclic siloxane substitute.
