Cyclopentasiloxane
FunctionSilicone
What it is — Cyclopentasiloxane (INCI: Cyclopentasiloxane), also called D5, is a lightweight, fast-evaporating cyclic silicone carrier.
What it does — It is commonly used to give a smooth, silky, dry-touch slip and to help thin and spread heavier ingredients, leaving little residue as it evaporates.
Typical use — It appears in primers, hair serums, moisturizers and makeup.
Who it suits / good to know — Suits those who like a weightless finish. Cyclic siloxanes are effective texture agents but face growing environmental scrutiny in some regions.
Safety — DHALIORA grades it mid risk: considered well tolerated on skin, but cyclic siloxanes face environmental restrictions in some regions. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.
