Carbomer 940 (CAS 9007-16-3) is a high-viscosity cross-linked polyacrylic acid polymer — the classic thickener for clear gels, creams and lotions. It creates elegant, crystal-clear gel textures with excellent suspension properties. Physical & Chemical Properties INCI: Carbomer CAS number: 9007-16-3 Appearance: white fluffy powder Solubility: swells in water to form clear gels (neutralized) Ionic type: […]
Vitamin E (Tocopherol, CAS 59-02-9) is a lipid-soluble antioxidant that protects skin from oxidative stress, supports moisture retention and complements anti-aging systems. It is equally essential in dietary supplements. Physical & Chemical Properties INCI: Tocopherol CAS number: 59-02-9 Appearance: pale yellow to amber viscous oil Solubility: oil-soluble; practically insoluble in water Molecular formula: C29H50O2 Ionic […]
Niacinamide (Vitamin B3, CAS 98-92-0) is one of the most versatile skincare actives — it brightens, strengthens the barrier, controls sebum and calms redness. Its broad efficacy and excellent tolerance make it a staple in serums, moisturizers and acne-care products. Physical & Chemical Properties INCI: Niacinamide CAS number: 98-92-0 Appearance: white crystalline powder Solubility: freely […]
Kojic Acid (CAS 501-30-4) is a classic brightening active derived from fungal fermentation. It inhibits tyrosinase — the key enzyme in melanin production — making it a proven ingredient for evening skin tone and fading pigmentation. Physical & Chemical Properties INCI: Kojic Acid CAS number: 501-30-4 Appearance: white to pale yellow crystalline powder Solubility: soluble […]
Alpha Arbutin (CAS 84380-01-8) is a naturally inspired brightening active that gently inhibits tyrosinase to even skin tone and fade dark spots. Its excellent safety profile makes it a preferred choice for daily brightening serums and spot treatments. Physical & Chemical Properties INCI: Alpha-Arbutin CAS number: 84380-01-8 Appearance: white to off-white crystalline powder Solubility: soluble […]
Allantoin (CAS 97-59-6) is a gentle, multi-functional active that soothes irritation, supports skin repair and smooths rough skin. It is a trusted ingredient in sensitive skincare, baby care, after-shave and dermatological formulas.
