Cyclopentasiloxane

INCI Cyclopentasiloxane

Volatile Silicone / Slip Agent Formula Support

What it is & what it does

Cyclopentasiloxane is a volatile silicone that improves slip and reduces heavy or greasy feel.
WHAT IT IS: Cyclopentasiloxane is a volatile silicone fluid used mainly to improve the spread, slip and dry-down of a cosmetic formula.

WHAT IT DOES / EVIDENCE: It evaporates after application and can leave a smoother, lighter skin feel while helping other ingredients distribute evenly. This is an important sensorial and formulation function, not evidence that the ingredient independently treats wrinkles, pigmentation or acne.

IN THE FINISHED FORMULA: Its appropriate classification is texture and application support, not a stand-alone biological treatment active. The actual function depends on raw-material identity and product design.

Usage & cautions

Use according to the finished product's directions; avoid inhalation in products that warn about aerosol exposure.
