NaturaSyn Introduces High-Purity D-Biotin for Advanced Cosmetic Formulations

Tianjin, March 10, 2026– NaturaSyn,  today announced the availability of its high-purity D-Biotin (Vitamin B7 / Vitamin H) for the personal care and cosmetics industry. As consumer demand for science-backed beauty ingredients continues to surge, NaturaSyn Biotin offers formulators a versatile and effective solution for hair strengthening, skin barrier repair, and nail care products.

Biotin, also known as Vitamin H—derived from the German words "Haar und Haut" (hair and skin)—is an essential water-soluble coenzyme that plays a critical role in keratin infrastructure and epidermal barrier function . It acts as a key CO2 carrier in carboxylation reactions, supporting the metabolism of fatty acids, amino acids, and energy production that are vital for healthy hair and skin tissue .

Cosmetic Applications: Beyond Basic Nutrition

While biotin is widely recognized in the nutraceutical sector, its topical applications in cosmetics are gaining significant momentum. Market analysis indicates that the cosmetic industry now accounts for approximately 25-30% of global biotin consumption, driven by increasing incorporation into premium hair care, skin care, and nail formulations .

For Hair Care Applications
NaturaSyn Biotin strengthens hair follicles by activating keratin synthesis, helping to reduce breakage and split ends while improving overall hair resilience and shine . When incorporated into serums and leave-on treatments, it supports hair follicle health and oxygenation . Advanced studies demonstrate that biotin can enhance the expression of hair-related keratins in follicle keratinocytes and promote hair growth genes in dermal papilla cells .

For Skin and Nail Health
In skincare formulations, biotin helps maintain barrier integrity and supports epidermal lipid homeostasis, making it particularly effective for dry or compromised skin conditions . It assists in regulating fat production and improving tissue elasticity, which contributes to a healthier, more resilient skin appearance . For nail care, biotin is clinically recognized for its ability to increase nail hardness and thickness, addressing brittleness and fragility over continued use .

Product Specifications and Formulation Guidelines

NaturaSyn Biotin (INCI: Biotin) is supplied as a white to off-white crystalline powder with a purity of ≥98% . The product exhibits a water solubility of approximately 220 mg/L at 25°C, allowing for flexible incorporation into various cosmetic matrices.

• Recommended Usage Level: ≤1% for leave-on products per SCCS guidelines; efficacy in hair products can be observed at levels as low as ≥0.01% for keratin gene expression activation .

• Compatibility: Pairs effectively with complementary ingredients such as panthenol, niacinamide, ceramides, and hydrolyzed collagen for synergistic barrier repair and conditioning benefits .
