China Origin 5% Astaxanthin Astaxanthin Oil Haematococcus Pluvialis Extract CAS 472-61-7

Introduction：

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 needsacross 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.

Specification:

As a concentrated lipid extract derived from Haematococcus pluvialis microalgae, Astaxanthin Oil (i.e., Haematococcus pluvialis extract) is valued for its high content of natural esterified astaxanthin. Production involves cultivating select algal strains, harvesting astaxanthin-rich cysts, then breaking cell walls and extracting. The resulting oil retains the full spectrum of source bioactives—a potent, stable natural astaxanthin.

Its deep red color and mild algal aroma set it apart from extracts with strong fishy notes. The process employs food-grade ethanol to keep solvent residues minimal. Excellent fluidity and homogeneity at room temperature make it a premium ingredient suited for high-end formulations in nutraceuticals, cosmetics, and functional foods.

Application

1. Nutritional Supplements

Astaxanthin Oil is widely used in the dietary supplement sector, particularly in formats that maximize bioavailability. Its lipid-soluble nature makes it an ideal candidate for:

-Softgel capsules: The most common delivery format, ensuring stable encapsulation and efficient absorption.

-Liquid drops: Suitable for sublingual or mixed administration, offering flexible dosing.

-Oil-based formulations: Often combined with other fat-soluble nutrients like vitamin E or omega-3 fatty acids for synergistic effects.

Supplements formulated with Astaxanthin Oil cater to consumers seeking natural support for anti-aging, cardiovascular health, immune function, and athletic recovery.

2. Functional Foods and Beverages

As consumer interest in health-promoting foods grows, Astaxanthin Oil presents a valuable opportunity for product differentiation. Its natural red-orange hue and oxidative stability make it suitable for:

-Dairy products: Yogurts, milk drinks, and cheese spreads benefit from both color enhancement and antioxidant protection.

-Cooking oils and dressings: A clean-label addition that helps delay rancidity while adding functional value.

-Beverages: Emulsified systems such as fruit juices, smoothies, and wellness shots can incorporate Astaxanthin Oil with proper formulation techniques.

-Confectionery and baked goods: Functional bars, gummies, and snacks can leverage its natural color and health halo.

When used in functional foods, Astaxanthin Oil serves a dual role—improving nutritional profile while contributing to product stability and shelf appeal.

3. Cosmetics and Nutricosmetics

The beauty industry has embraced Astaxanthin Oil for its exceptional antioxidant capacity and skin compatibility. Its lipid solubility facilitates penetration into the stratum corneum, allowing for targeted delivery of active compounds. Key applications include:

-Anti-aging skincare: Serums, creams, and masks formulated to reduce oxidative stress, improve elasticity, and diminish fine lines.

-Sun care: Provides supplementary photoprotection when used in combination with UV filters.

-Lip care: Imparts natural color while offering moisturizing and protective benefits.

-Nutricosmetics: Oral beauty formulations such as softgels and drinks that support skin health from within.

Astaxanthin Oil is particularly valued in premium cosmetic lines where efficacy, natural origin, and clean-label credentials are paramount.

4. Animal Nutrition and Aquaculture

In the feed industry, Astaxanthin Oil is recognized as the benchmark for natural pigmentation. Its key advantages include:

-Direct deposition: Unlike other carotenoids, astaxanthin does not require metabolic conversion in species such as salmon, trout, and shrimp, leading to efficient and consistent coloration.

-Health benefits: Beyond pigmentation, it supports immune function, stress resistance, and overall vitality in farmed animals.

-Egg yolk enhancement: In poultry, it enriches yolk color to meet consumer expectations for naturally raised products.

For producers targeting premium markets, Astaxanthin Oil offers a reliable, natural solution that aligns with clean-label and sustainability trends.

Q&A

Q1: Why is Astaxanthin Oil particularly suitable for high-fat foods and oil-based supplements?

A1: As a fat-soluble compound, Astaxanthin Oil disperses evenly in lipid-rich matrices without altering taste or texture. It serves a dual function: providing natural red-orange coloration while helping to prevent lipid oxidation, thereby extending product shelf life and maintaining sensory quality.

Q2: Why is Astaxanthin Oil superior for aquafeed pigmentation?

A2: 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.

Q3: What makes Astaxanthin Oil more effective than other antioxidants?

A3: Astaxanthin's unique molecular structure allows it to span cell membranes, protecting both lipid and aqueous environments simultaneously. This dual-action mechanism, combined with its superior free radical scavenging capacity—up to 6,000 times stronger than vitamin C and 550 times stronger than vitamin E—sets it apart from conventional antioxidants.

Q4: What are the advantages of using Astaxanthin Oil in cosmetic formulations?

A4: Three key advantages make it a preferred choice for skincare formulators:

-Potent efficacy: A powerful antioxidant that combats oxidative stress, a primary driver of skin aging.

-Formulation versatility: High lipid solubility allows seamless integration into emulsions, oils, and balms.

-Skin compatibility: Well-tolerated, non-irritating, and readily absorbed without leaving a greasy residue.

Q5: How do I choose the right Astaxanthin Oil concentration for my product?

A5: The optimal concentration depends on your application and target potency:

-10%: Best suited for high-potency supplements and concentrated anti-aging serums where maximum efficacy is required.

-5% & 2%: Well-matched for daily skincare products, functional foods, and general nutritional supplements.

-1%: A practical, cost-effective option for large-scale aquaculture feed, poultry nutrition, and mass-market applications.

Q6: Can Astaxanthin Oil be combined with other functional ingredients?

A6: Yes. Astaxanthin Oil exhibits good compatibility with other fat-soluble ingredients such as vitamin E, coenzyme Q10, omega-3 fatty acids, and various botanical oils. In formulations, it can be used synergistically to enhance overall antioxidant capacity and broaden health benefits.
