100% Water-soluble Vitamin E Polyethylene GlycolSuccinate (TPGS)

For over a decade, KEEP INGREDIENTS has supplied premium-grade Vitamin E TPGS (D-α-Tocopheryl Polyethylene Glycol Succinate) — a USP39-certified, multifunctional ingredient revolutionizing bioavailability in nutraceuticals, functional foods, and cosmetics. Our TPGS (CAS 9002-96-4) transforms lipid-soluble actives into water-miscible solutions, unlocking unprecedented formulation potential.

Core Advantages for Functional Applications

1. Superior Solubility & Bioavailability

TPGS converts fat-soluble compounds (e.g., vitamins, curcumin, CoQ10) into clear aqueous solutions, increasing solubility by 2–16x3. Its micelle-forming structure enhances intestinal absorption, making it ideal for low-fat diets or age-related nutrient uptake challenges.

Enables transparent fortification of beverages, gummies, and dairy—no cloudiness or separation79.

2. Multifunctional Performance

Stability & Emulsification: Heat-stable up to 200°C, TPGS extends shelf-life in functional foods and cosmetics at just 1% usage (vs. traditional surfactants)3.

Synergistic Nutrient Protection: Acts as an antioxidant shield, recycling other antioxidants like Vitamin C and protecting sensitive actives during processing18.

3. Safety & Compliance

USP39 Certified: Rigorous third-party testing confirms:

≥25% D-α-tocopherol content (exceeding USP standards)

Ultra-low heavy metals (Pb <0.1ppm, Hg <0.01ppm) and microbial contaminants (<10 CFU/g)1.

Globally compliant with FDA, EU, and China regulations for foods, supplements, and cosmetics.
