Role of Beta Carotene Powder (CAS Number: 7235-40-7) in Beauty Supplements

In the ever-expanding world of beauty and wellness, the intersection of nutrition and cosmetic science is becoming increasingly relevant. Among the many active ingredients that have emerged as critical components in beauty supplements, beta carotene powder, identified chemically by the CAS Number: 7235-40-7, stands out for its multifunctional properties. This naturally occurring pigment, a member of the carotenoid family, is renowned not only for its role as a provitamin A compound but also for its powerful antioxidant activity. In this blog post, CASOV, a high performance cosmetic ingredients manufacturer, will share the role of beta carotene powder in beauty supplements for sale.

What is Beta Carotene Powder (CAS Number: 7235-40-7)?

Beta carotene is a lipophilic (fat-soluble) compound predominantly found in fruits and vegetables with orange and red hues, such as carrots, sweet potatoes, pumpkins, and mangoes. As a carotenoid, beta carotene is part of a broader group of phytochemicals that plants produce for photoprotection and pigment. In supplement form, beta carotene is usually provided as a stabilized powder, making it easier to incorporate into capsules, tablets, powders, and functional foods.

Its chemical structure consists of a 40-carbon skeleton with conjugated double bonds, which are responsible for both its vibrant color and its antioxidant activity. The CAS number 7235-40-7 refers specifically to all-trans-beta-carotene, the most stable and biologically active isomer.

Biological Function and Conversion to Vitamin A

Beta carotene is classified as a provitamin A carotenoid, meaning the human body can convert it into retinol (vitamin A) through enzymatic cleavage in the intestinal mucosa. This conversion is regulated based on the body' s vitamin A levels, making beta carotene a safe and efficient source compared to preformed retinol, which can accumulate to toxic levels.

Vitamin A is essential for:

* Skin health and epithelial tissue maintenance

* Cell differentiation and proliferation

* Sebum regulation

* Immune function

* Wound healing

Because of this role, beta carotene serves as a *nutritional precursor* for skin health and plays an integral part in maintaining a vibrant and youthful appearance.

Antioxidant Mechanism of Beta Carotene Powder in Beauty Applications

The conjugated double bonds in beta carotene enable it to neutralize free radicals, particularly singlet oxygen and peroxyl radicals, which are generated by ultraviolet (UV) radiation and environmental pollutants. These reactive oxygen species (ROS) accelerate the aging process through oxidative stress, leading to:

* Degradation of collagen and elastin

* Hyperpigmentation

* Wrinkle formation

* Dull, dehydrated skin

By acting as a scavenger molecule, beta carotene mitigates oxidative damage and helps in maintaining the structural integrity of skin cells. This is particularly valuable in beauty supplements targeting anti-aging, photoprotection, and skin luminosity.

Photoprotective Properties

Oral supplementation with beta carotene has been demonstrated in several clinical trials to confer a degree of internal photoprotection. When taken consistently, beta carotene accumulates in the epidermis and dermis, where it absorbs and diffuses UV rays before they can damage cellular DNA. Although not a substitute for topical sunscreens, this systemic protection complements topical defenses and reduces skin erythema (redness) caused by sun exposure.

Studies show that daily intake of 15–30 mg of beta carotene over 10–12 weeks can enhance the skin' s natural defense against UV-induced damage. For this reason, beta carotene is frequently found in sun-protection supplements and after-sun formulations.

Skin Tone and Glow Enhancement

Beta carotene' s pigmentation effect also plays a cosmetic role in enhancing skin tone. It imparts a natural golden hue to the skin when consumed in moderate amounts, a phenomenon termed carotenemia. Unlike the yellowing of jaundice, this tint is considered attractive and healthy, often associated with a youthful appearance.

This feature is increasingly leveraged in beauty supplements marketed for a radiant glow, as studies have indicated that carotenoid-rich skin is perceived as healthier and more attractive compared to melanin-induced tanning.

Hair and Nail Health

While the effects of beta carotene on hair and nails are less direct, its conversion into vitamin A contributes to the regulation of sebum production, which is crucial for scalp health. Adequate vitamin A levels help maintain the hydration and resilience of the scalp and hair follicles, promoting:

* Reduction in dandruff and scalp irritation

* Improved keratinization of hair shafts

* Prevention of hair brittleness and thinning

Additionally, the antioxidant properties help protect the hair follicles from oxidative stress, a known contributor to premature graying and hair loss.

Formulation Considerations in Supplements

1. Bioavailability

One of the primary challenges in supplementing with beta carotene powder is ensuring optimal bioavailability. As a lipophilic compound, its absorption is significantly enhanced when consumed with dietary fats. Supplement formulators often pair beta carotene with medium-chain triglycerides (MCTs) or lecithin to improve intestinal uptake.

2. Stability

Beta carotene is sensitive to light, heat, and oxygen, and thus requires careful stabilization. Modern encapsulation technologies, including microencapsulation, spray-drying, and liposomal delivery, are commonly employed to preserve its integrity.

3. Dosage

In beauty supplements, dosages typically range between 3 mg to 15 mg per day, depending on the intended benefit (e.g., antioxidant support vs. photoprotection). However, excessive intake may lead to benign carotenodermia, where the skin turns yellow-orange, especially on the palms and soles. This condition is reversible and not harmful, but aesthetically undesirable.

4. Synergistic Ingredients

Beta carotene often appears in formulations alongside other antioxidants such as:

* Vitamin E (tocopherol) – regenerates oxidized beta carotene

* Vitamin C (ascorbic acid) – supports collagen synthesis and antioxidant network

* Lycopene, lutein, and zeaxanthin – complementary carotenoids for enhanced skin defense

* Coenzyme Q10 and astaxanthin – improve mitochondrial function and reduce fine lines

This synergistic approach is fundamental in holistic beauty supplement design, aiming to address multiple skin-aging pathways simultaneously.

Conclusion

Beta carotene powder offers a compelling blend of nutritional functionality, antioxidant potency, and cosmetic appeal, making it a staple in modern beauty supplement formulations. Its ability to protect skin from oxidative stress, enhance dermal appearance, and serve as a safe precursor to vitamin A places it at the crossroads of health and aesthetics. As research continues to evolve, its role in nutricosmetics is expected to deepen, aligning with the growing consumer demand for natural, science-backed beauty solutions from within.
