Cosmetic Grade Dimethiconol-CAS 70131-67-6
Cosmetic Grade Dimethiconol is a high-purity hydroxyl-modified silicone oil refined by professional molecular purification technology. Relying on unique terminal hydroxyl functional structure, it achieves ultra-high adhesion and flexible breathable film-forming performance, making up for the defects of weak adhesion and short moisturizing duration of ordinary dimethicone.
It can efficiently lock skin moisture, repair damaged skin barrier, improve dry and rough skin texture, and bring long-lasting soft and smooth skin feeling without tightness.
In hair care formulas, it firmly fits the hair cuticle, repairs damaged dry hair, smooths frizzy hair, reduces static tangling, and endows hair with lasting softness and gloss. With mild formula, stable performance and wide compatibility, it is an indispensable core raw material for long-acting moisturizing, barrier repair and gentle smoothing skin and hair care products.
