Detailed Introduction of Phloretin

Phloretin is exclusive lipophilic dihydrochalcone polyphenol monomer from apples. Different from water-soluble phlorizin, it features outstanding transdermal penetration, making it core high-purity botanical raw material for premium brightening serums, penetration-boosting preparations and metabolic pharmacological research worldwide. We adopt bark & peel from standardized eco apple base, integrated ethanol extraction & multi-stage chromatography recrystallization technology to fully remove interfering tannin, polysaccharide and miscellaneous flavonoids. Finished product delivers pure single HPLC peak with batch fluctuation controlled within 0.3%, fully meeting strict QC requirements of high-end cosmetic brands, oral pharmaceutical factories and university new drug screening.

 

Phloretin owns rare dual-industry core advantages: For skincare, it provides powerful tyrosinase inhibition, broad-spectrum anti-oxidation and unique penetration enhancement, greatly improving skin absorption of VC, niacinamide, asiaticoside and other actives; For pharma & nutraceuticals, it blocks GLUT glucose transporters to assist glucose metabolism regulation, with anti-inflammation & UV DNA repair activity. Compatible with alcohol serums, ointments, liposomes and oral tablets, it delivers synergistic effects when blended with brightening & repair actives.

 

The whole closed-loop production runs under low light & low temperature to prevent polyphenol oxidation caused by phenolic hydroxyl groups. Pesticide residues, heavy metals and residual solvents all meet EU & US import limits. Stable ton-level bulk stock with full chromatograms & compliance docs per batch, offering one-stop service for global cosmetic manufacturers, nutraceutical traders and pharmaceutical R&D labs.

Common Questions

FAQ About Sponge Phloretin

1. What is the core difference between Phloretin and Phlorizin?
Phloretin is lipophilic aglycone with superior penetration boosting; Phlorizin is water-soluble glycoside focusing on oral metabolic regulation, with totally different formula scenarios. We supply 98% pure phloretin.
Phenolic hydroxyl groups oxidize easily under light, store sealed at 2–8℃ without light exposure, finish within 3 months after opening & avoid moist air.
All indicators comply with USP, EP & EU cosmetic regulations, complete SGS, MSDS, COA docs support global customs & registration.
Tyrosinase inhibition for brightening, anti-photoaging antioxidant, unique penetration booster, widely used in premium serums.
5. What is the solubility of Phloretin?

Freely soluble in ethanol & DMSO, barely soluble in cold water, requires alcohol or lipid carrier for formulations.

Yes, compound with licorice flavonoids & asiaticoside as integrated brightening repair raw materials.
Self-owned apple base & recrystallization line, full HPLC per batch with ≤0.3% content fluctuation for long-term mass stock.
Free samples are unrestrictedly available for full polyphenol analysis at international certified laboratories.
