Cosmetic Grade Hyaluronic Acid Powder CAS 9004-61-9

Detailed Product Description

Chemical Composition and Molecular Structure of Hyaluronic Acid

Hyaluronic Acid (HA) is a naturally occurring glycosaminoglycan composed of repeating units of D-glucuronic acid and N-acetyl-D-glucosamine, represented by the molecular formula (C₁₄H₂₁NO₁₁)ₙ. Its structure enables high water-binding capacity, making it an exceptional moisture-retaining raw material for cosmetic formulations. HA exists in a linear polymer form with alternating β-(1→3) and β-(1→4) glycosidic bonds, contributing to its viscoelastic properties. Cosmetic Grade HA powder from Shaanxi Bolin Biotechnology maintains purity standards exceeding 99%, ensuring consistent functional performance across diverse skincare applications.

Scientific Mechanism of Skin Moisturisation and Anti-Aging Effects

Hyaluronic Acid’s hydrophilic structure allows it to attract and hold water molecules up to 1,000 times its own weight, forming a protective hydration layer on the skin surface. This moisture regulation enhances skin elasticity, smoothness, and texture, reducing the appearance of fine lines and wrinkles. Scientific studies (Journal of Cosmetic Dermatology, 2021; International Journal of Molecular Sciences, 2020) confirm that topically applied HA penetrates the stratum corneum effectively, maintaining skin hydration even in low-humidity environments. The anti-aging effect is further reinforced by HA’s interaction with dermal fibroblasts, stimulating collagen synthesis and supporting long-term skin firmness.

Available Molecular Weight Grades and Their Target Cosmetic Applications

Shaanxi Bolin Biotechnology offers two distinct molecular weight ranges for targeted applications:

· Low Molecular Weight HA (3000–5000 Dalton): Penetrates deeper skin layers, ideal for anti-aging serums, eye creams, and intensive treatment masks.

· High Molecular Weight HA (1.8M–2.0M Dalton): Forms a surface hydration barrier, providing immediate moisturisation and enhancing the texture of lotions, creams, and facial masks. Combining different molecular weights enables layered skin hydration, ensuring multi-level moisturizing and elasticity benefits.

Quality Control Standards and Testing Protocols

Shaanxi Bolin Biotechnology implements rigorous quality assurance processes to maintain consistent HA powder performance.

· Analytical Test Methods: High-Performance Liquid Chromatography (HPLC) and Ultraviolet (UV) Spectroscopy.

· Physical Inspection: Fine white powder appearance, no foreign particles.

· Purity Standards: ≥99%, verified through standardized assays.

· Mesh Size Compliance: Powder passes NLT 95% through 80 mesh screens. These robust testing protocols ensure the HA powder meets global cosmetic industry expectations and provides reliable formulation performance.

Global Certifications and Compliance Status

Cosmetic Grade HA powder is validated by multiple international certifications, ensuring its compliance with global B2B standards:

· ISO, HACCP, CQC – Quality and safety management systems.

· KOSHER and HALAL – Meeting religious and dietary standards.

· ORGANIC Certification – Supports natural and eco-conscious formulations.

· SGS Inspection – Independent verification of product purity and safety. These credentials reinforce trustworthiness for international cosmetic manufacturers.

Proper Storage and Handling Guidelines

· Store in a cool, dry environment away from direct sunlight.

· Maintain temperature below 25°C and relative humidity below 60%.

· Keep packaging sealed to prevent moisture absorption.

· Shelf life: 2 years under proper storage conditions. Adhering to these protocols ensures optimal HA stability, functionality, and shelf life.

Formulation Compatibility and Usage Recommendations

Cosmetic Grade HA powder demonstrates excellent compatibility across various formulation types:

· Emulsions: Creams, lotions, and serums.

· Hydrogel-based formulations: Facial masks, eye pads.

· Powder-to-liquid applications: Rehydrated HA solutions and ampoules. Recommended usage concentrations:

· 0.1–0.5% for surface hydration and texture improvement.

· 0.5–2% for intensive moisturisation and anti-aging effects. Its neutral pH and water solubility enable seamless integration without altering formulation stability.
