Astaxanthin with CAS 472-61-7

Astaxanthin with CAS 472-61-7 is a ketocarotenoid, most commonly identified in marine and aquatic animals, including krill, wild salmon, rainbow trout, microalgae, shells of lobster, shrimp, seafood products, etc. It is biologically known as a vitamin A precursor, and exhibits strong antioxidant property, much higher compared to vitamin E and β-carotene. Its role in food and the medicinal industry is also well-defined.

Astaxanthin with CAS 472-61-7 can be used to develop natural and healthy products for enhancing immunity, anti-oxidation, anti-inflammatory, eye and brain health, regulating blood lipids and other aspects. At present, it is mainly used as the raw material of advanced health food and medicine for human beings; feed additives for aquaculture (mainly salmon, trout and salmon), poultry breeding; cosmetic additives. It can significantly improve the immunity of the human body, because it can not specifically bind to skeletal muscle, can effectively remove free radicals generated by exercise in muscle cells, strengthen aerobic metabolism, so it has a significant anti-fatigue effect. It is the only carotenoid that can pass through the blood-brain barrier. It has a real anti-aging effect. Effective antioxidant is the basis of all cosmetic activities. Because of its super antioxidant effect, it can be used.

Application

1. Dietary supplements / Nutritional supplements: Soft capsules, tablet candies, solid drinks, sports nutrition powders. Main functions: eyesight protection, anti-fatigue, antioxidant, cardiovascular care, post-exercise muscle oxidation repair and immune support. Haematococcus pluvialis natural astaxanthin is preferred for this application.

2. Cosmetics & Personal Care: Serums, creams, sunscreens, eye creams, masks. It delivers anti-photoaging effects, scavenges free radicals, repairs UV damage, improves dullness and fine wrinkles. It can also act as a natural red colorant.

3. Functional foods: Functional beverages, dairy products, meal replacements, baked foods. For nutrition fortification and natural red coloring.

4. Aquatic & Poultry Feed: Applied in feed for salmon, rainbow trout, shrimp, crabs and ornamental fish to color flesh and shells. Added to poultry feed to deepen egg yolk pigmentation. It also improves stress resistance and survival rate of farmed animals. Synthetic astaxanthin is widely used in the feed industry.

Features

1. Strong antioxidant: Liposoluble carotenoids can cross the complete cell membrane and eliminate free radicals; unlike vitamin C and vitamin E, they will not be converted into pro-oxidants in a highly oxidized environment.

2. Unique penetration: It can penetrate the blood-retina barrier and the blood-brain barrier, protecting the eyes, supporting the antioxidant function of the optic nerve and the brain, and is one of the few carotenoids with this characteristic.

3. High-quality configuration: The biological utilization rate is higher than the synthetic racemate, and it is preferred by customers of health supplements and cosmetics.

4. Compatible in multiple scenarios: Liposoluble, it can be made into astaxanthin oil, algae powder, microcapsule water-soluble powder; suitable for soft capsules, powders, essences, face creams, sunscreens, and aquatic feed.

5. Light protection against photoaging (cosmetics): Resists UV oxidative damage, repairs photoaging, improves fine lines, and brightens the skin. Suitable for internal beauty care + external skin care formulas.

6. Eye protection (health supplements): Relieves blue light and eye fatigue, protects the macula; in the sports nutrition direction, it can reduce oxidative stress, accelerate muscle recovery, and reduce lactic acid accumulation. AstaReal.

7. Natural coloring (feed / food): Natural red pigment, enhances the color of salmon and ornamental shrimp, and simultaneously improves the stress resistance and survival rate of farmed animals.

8. Factory supply advantages: Multiple specifications, food grade / cosmetic grade / feed grade options available; can provide COA, HPLC, compliance documents, support for samples, batch export, and custom indicators.
