【Core Benefits】
Cooling Sensation – Strong yet Gentle: Cooling intensity close to menthol, with significantly lower irritation. Cooling lasts up to 6–8 hours with slow decay. No “instant cold burst” irritation of menthol – suitable for sensitive skin and infant products.
Safety – Low Irritation, Low Allergenicity: Transdermal irritation markedly lower than menthol. Unlikely to cause skin redness or itching, offering greater peace of mind.

Multifunctional Properties:
– Cooling & soothing: ideal for post‑sun, stuffy heat, oily scalp, and summer products.
– Sebum control & conditioning: reduces sebum secretion – suitable for oily/acne‑prone skin.
– Supports microcirculation: commonly used in scalp care and eye area products.
