It retains the antioxidant and anti-photoageing benefits of natural rutin while fully resolving three major pain points: poor solubility, insufficient stability and low skin penetration. Listed in China's Inventory of Cosmetic Ingredients, high-purity glucosylrutin produced via green intelligent manufacturing by Invertin Biotech. Sample applications are now open.
I. Rutin Has Great Merits, Yet Poor Water Solubility Puzzles Formulators
Rutin (rutoside) is a household name among cosmetic R&D professionals. A natural flavonoid glycoside extracted from pagoda tree flower buds and citrus peels, it delivers outstanding performance in microcirculation improvement, antioxidation and anti-photoageing.
Nevertheless, formulators have mixed feelings about it. Its "extremely low water solubility" is a critical drawback:
❌ Hard to formulate into aqueous skincare systems; precipitation readily occurs.
❌ Formulations tend to discolour, making stability hard to control.
❌ Poor transdermal penetration and disappointingly low bioavailability.
Natural polyphenols boast powerful antioxidant properties, but are we forced to give up on this promising ingredient?
Absolutely not! Today, using green biosynthesis technology, we equip rutin with a "water-soluble protective shell" - Glucosylrutin!
II. Core Modification: One Extra Glucose Molecule Brings Dramatic Property Changes
Glucosylrutin is a rutin derivative modified by enzymatic glycosylation technology. A glucose molecule is precisely attached to the molecular structure of rutin. This subtle molecular "reengineering" achieves the breakthrough from nearly insoluble to highly water-soluble.
| Properties | Conventional Rutin | Glucosylrutin |
|---|---|---|
| Water Solubility | Extremely low; prone to precipitation | Greatly enhanced; easily incorporated into aqueous systems |
| Stability | Susceptible to oxidation and discoloration | Improved light and heat resistance |
| Transdermal Bioavailability | Poor absorption | Markedly increased bioavailability |
III. Efficacy Evidence: What Can It Deliver?
Glucosylrutin inherits the excellent bioactivity of natural rutin. Thanks to its optimised physicochemical properties, its bioavailability in the human body is substantially improved. Multiple authoritative domestic and international research papers confirm that glucosylrutin preserves the core bioactivity of rutin and demonstrates more consistent efficacy due to enhanced solubility.
1. Potent Antioxidation
In vitro studies show that at 0.1% concentration, glucosylrutin scavenges DPPH free radicals approximately 40% more effectively than vitamin C. It efficiently neutralises reactive oxygen species (ROS) and suppresses oxidative stress, exhibiting notable performance in anti-ageing, photoageing prevention and mitigating UV-induced DNA damage.
2. Dual Protection against UV and Blue Light
Glucosylrutin features strong UV absorption capacity. It slows UV-triggered collagen degradation and alleviates UV-induced skin inflammation and redness. Research also verifies that the ingredient effectively absorbs blue light, making it suitable for blue-light defence skincare products.
3. Potential Cardiovascular Benefits and Anti-glycation Effects
Studies indicate glucosylrutin can stabilise vascular endothelium and improve blood circulation. It also shows potential for inhibiting tissue glycation (anti-glycation) and reducing visceral fat. Most research in these areas remains at the fundamental or animal-testing stage; further human clinical trials are required for validation.
4. Neuroprotective and Anti-allergic Potential
Preliminary research suggests it may exert anti-allergic and neuroprotective effects. It is commonly utilised in dietary supplements and functional materials, yet its exact effects in humans require further investigation.
IV. Formulator Corner: Compatibility Recommendations & Dosage
Cosmetic Applications
- Regulatory Status: Glucosylrutin is included in the Inventory of Existing Cosmetic Ingredients (2021 Edition) (No.05113) and is not a prohibited substance. The recommended usage level for leave-on products for general body application is 0.5%, with a typical addition range of 0.1%–2%.
- Suitable Products: eye creams, night creams, serums, masks, sunscreens, after-sun repair products, water-based sun care products, etc.
- Compounding Recommendations:
- Synergise with classic antioxidants such as Vitamin C + Vitamin E to build an antioxidant defence network.
- Combine with brightening ingredients including oxyresveratrol and 3-O-ethyl ascorbic acid for synergistic effects.
- Pair with humectants such as glyceryl glucoside and sodium hyaluronate to strengthen skin repair.
Oral Supplement Applications
- Recommended Dosage: In European and American markets, glucosylrutin is used in dietary supplements (to support vascular health, anti-inflammation, etc.). The suggested daily intake ranges from 50–200 mg.
- Application Directions: improve microcirculation, auxiliary antioxidation, maintain cardiovascular health.
- Dosage Forms: tablets, capsules or oral liquids.
⚠️ Special Regulatory Reminder for China
Glucosylrutin is approved for cosmetic use in China. However, it is not yet explicitly listed as an allowable raw material for health food or ordinary food. If intended for oral products, pre-submission and compliance review with the State Administration for Market Regulation or relevant competent authorities are mandatory. The oral efficacy statements in this article are for scientific research and overseas market reference only and do not constitute compliance advice for the Chinese market.
