Astaxanthin Oil is a naturally occurring, lipid-soluble xanthophyll carotenoid. Presented as a dark red, free-flowing oily liquid, it is available in concentrations of 10%, 5%, 2%, and 1% to precisely meet diverse formulation needs across food, feed, and cosmetics industries. As the terminal endpoint of carotenoid synthesis, astaxanthin possesses a unique molecular structure that allows for direct deposition in animal tissues without in-vivo modification. This characteristic, combined with exceptionally potent antioxidant activity, distinguishes it from other carotenoids. Sourced primarily from premium Haematococcus pluvialis microalgae, it is a non-provitamin A carotenoid celebrated for high biocompatibility. Its safety is well-documented through numerous in-vivo and in-vitro studies, and it holds GRAS (Generally Recognized as Safe) status for dietary use. This exceptional safety profile, coupled with natural origin and powerful functionality, positions Astaxanthin Oil as an ideal choice for developing next-generation, science-backed products.

Application
1. Food and Health Field
Harness the power of nature with Astaxanthin Oil, a natural, fat-soluble pigment that delivers both vibrant red color and potent antioxidant protection. Its excellent compatibility with lipid-rich food matrices makes it an ideal "clean label" ingredient. It not only enriches products with dietary carotenoids but also actively helps preserve the quality and freshness of raw materials and finished goods, perfectly aligning with the growing consumer demand for natural, health-promoting food products.
·Dietary Supplements: Ideal for the development of high-bioavailability softgels and oral liquids.
·Functional Foods: Serves as a natural colorant and quality enhancer in lipid-rich products like meat, dairy, and cooking oils.
·Nutritional Fortification: A natural pigment and nutrient booster for beverages, bakery items, and other processed foods, enhancing both visual appeal and nutritional value.
2. Feed Industry
Astaxanthin Oil is the gold standard for achieving optimal pigmentation in aquaculture and poultry. Its core value lies in its unparalleled ability to be deposited directly into animal tissues, effectively and naturally enhancing the coloration of muscle, skin, and egg yolks. This natural solution enables producers to meet the market's premium visual expectations for aquatic and poultry products without any adverse effects on animal physiology or metabolism.
·Aquaculture: A key feed additive for salmon, trout, sea bream, shrimp, and crabs, delivering the characteristic healthy red pigmentation to skin and muscle that consumers demand.
·Poultry Farming: Incorporated into feed to enrich the golden-yellow color of egg yolks, as well as the skin, shanks, and feathers of chickens, ducks, and geese.
3. Cosmetics Industry
Astaxanthin Oil is a game-changing active ingredient for modern skincare. Its exceptional antioxidant power—far exceeding that of many conventional ingredients—is perfectly complemented by its lipid solubility. This allows for seamless integration into oil-based and water-oil emulsion systems, ensuring uniform dispersion and enhanced dermal absorption. It empowers formulators to create innovative products that deliver on the promise of natural, functional efficacy.
·Facial Care: A potent additive for anti-aging creams, serums, and lotions, targeting oxidative stress.
·Lip Care: Provides natural color and protection in lip balms and glosses.
·Body Care: Easily blended into body lotions and hand creams for whole-body antioxidant support.
Q&A
Q1: What are the key specifications and physical properties of your Astaxanthin Oil?
A1: GEMSEN Astaxanthin Oil (CAS 472-61-7) is a dark red, lipid-soluble liquid. We supply it in four standard concentrations to suit different applications: 10%, 5%, 2%, and 1%, with custom concentrations available upon request.
Q2: Can Astaxanthin Oil be safely used in foods and supplements?
A2: Absolutely. Astaxanthin Oil has an excellent safety profile. It is GRAS (Generally Recognized as Safe) by the U.S. FDA for food applications. Studies have confirmed no toxic effects, even with short-term, high-dose intake, making it a safe and reliable ingredient for daily use.
Q3: What makes Astaxanthin Oil particularly effective in high-fat foods?
A3: As a fat-soluble compound, it disperses evenly in lipid-rich matrices without altering taste or texture. Its dual function as a natural red colorant and a potent antioxidant provides both visual appeal and extended shelf life by preventing lipid oxidation.
Q4: Why is Astaxanthin Oil superior for aquafeed pigmentation?
A4: Unlike other carotenoids, astaxanthin is the terminal product of carotenoid synthesis. This means aquatic species like salmon and shrimp can deposit it directly into their tissues without biochemical conversion. This results in superior, stable, and natural coloration with exceptional efficiency.
Q5: What are the technical benefits of using Astaxanthin Oil in cosmetics?
A5: It offers three key advantages:
·Superior Efficacy: A powerful antioxidant that combats skin aging.
·Formulation Versatility: Excellent lipid solubility allows for easy integration into various emulsions and oils.
·High Compatibility: It is biocompatible, readily absorbed, and non-irritating to the skin.
Q6: How do I choose the right Astaxanthin Oil specification for my product?
A6: The choice depends on your application and desired intensity:
·10%: Recommended for high-end supplements and potent, anti-aging cosmetic serums.
·5% & 2%: Ideal for general food products, daily skincare lotions, and creams.
·1%: A cost-effective solution for large-scale aquaculture and poultry feed manufacturing.
