First and foremost, Ellagic acid is a natural polyphenol tannin active ingredient extracted from pomegranate rind, gallnut and raspberry. This high-potency antioxidant raw material inhibits melanin formation, eliminates free radicals and delivers anti-inflammatory effects. For this reason, anti-aging cosmetic factories, whitening skincare brands and dietary supplement manufacturers widely adopt this standardized botanical powder for diversified production lines.
1. Basic Product Properties
To start with, ellagic acid presents pale yellow fine crystalline powder with nearly no peculiar odor. In addition, it dissolves slightly in ethanol and alkaline aqueous solutions, while barely soluble in neutral cold water. Meanwhile, light-proof sealed cool storage effectively prevents polyphenol oxidation and maintains stable bioactivity. On the contrary, long-term exposure to strong light and high temperature will cause discoloration and weaken antioxidant and brightening efficacy. Besides that, we supply HPLC purity grades of 98%–99% to meet pharmaceutical, food and cosmetic industrial standards.
2. Professional Production Technology
We select high-quality dried pomegranate peels as stable mass extraction feedstock. Firstly, workers crush and screen raw plant materials to remove fiber and impurity residues. Next, low-temperature alkaline water-alcohol reflux extracts crude polyphenol mixtures. After that, acid precipitation, macroporous resin purification and repeated recrystallization lift finished ellagic acid to target purity. Furthermore, every finished batch undergoes strict HPLC content, heavy metal and microbial limit testing. Thus, stable qualified Ellagic acid is ready for global bulk shipment.

3. Core Product Advantages
Compared with mixed fruit peel crude extract, our purified ellagic acid features fixed high polyphenol content with consistent batch stability. In addition, it combines antioxidant, melanin-inhibiting and anti-inflammatory triple functions to simplify multi-effect formula design. Moreover, triple food, cosmetic and pharmaceutical grades fit oral anti-oxidation supplements and topical brightening skincare separately. Meanwhile, pure natural plant source contains no synthetic whitening agents to satisfy clean-label and mild skincare demands.
4. Wide Application Fields
4.1 Antioxidant Anti-Aging Nutritional Supplements
For instance, it acts as core free radical scavenger in anti-aging oral capsules to slow cell aging and support internal oxidation balance.
4.2 Brightening Spot-Fading Skincare Formulas
Blend ellagic acid crystal powder into whitening serums and spot creams to restrain tyrosinase activity, lighten pigmentation and even skin tone.
4.3 Natural Food Antioxidant Preservatives
Beyond skincare usage, this polyphenol ingredient extends shelf life of fruit drinks, baked goods and meat products as plant-derived antioxidant additive.
