“Zero-additive” shampoos are trending, with Douyin views surpassing 100 million. Yet many deliver silky feel despite “no silicone” labels—thanks to volatile silicones like cyclopentasiloxane (D5).
Regulators permit these in rinse-off products because they evaporate during drying, leaving minimal residue. Thus, “silicone-free” usually means “no non-volatile silicone like dimethicone”—not zero silicones.
Common compliant types include D5, DC346 (D5 + dimethicone blend), and phenyl trimethicone. However, note that the EU lists D5 as an SVHC and will restrict it in leave-on products from 2027.
For honest labeling, brands should clarify: “Free of non-volatile silicones” or “Contains volatile silicones that rinse away.” Transparency—not omission—builds consumer trust in the clean-beauty era.
