N-Acetyl Glucosamine (NAG) | Cosmetic Grade

N-Acetyl Glucosamine (NAG) is a naturally derived amino sugar and a key precursor to hyaluronic acid biosynthesis. It is a multifunctional cosmetic active widely used in anti-aging, brightening, and barrier-repair formulations.

INCI Name: Acetyl Glucosamine
CAS No.: 7512-17-6
Grade: Cosmetic Grade
Purity (on dry basis): 98.0–102.0% (Our stock: 99.62%)
Appearance: White or near-white crystalline powder or particle
Shelf Life: 24 months
Origin: China

Key Benefits:

• Stimulates hyaluronic acid synthesis — boosts skin's natural moisture reservoir
• Inhibits melanin transfer — brightens skin tone and reduces hyperpigmentation
• Supports collagen production — improves skin firmness and elasticity
• Gentle exfoliant — promotes cell turnover without irritation
• Anti-inflammatory — soothes sensitive and reactive skin
• Suitable for all skin types including sensitive skin

Why Formulators Choose N-Acetyl Glucosamine:

• Hyaluronic Acid Precursor — Hydration from Within: NAG is a direct biosynthetic precursor to hyaluronic acid. When applied topically, it stimulates the skin's own HA production, providing deep, lasting hydration that goes beyond surface-level moisturization.
• Melanin Inhibition — Brightening Without Irritation: NAG inhibits the glycosylation of pro-tyrosinase, effectively reducing melanin synthesis. Unlike harsh brightening agents, it delivers a gradual, even skin tone improvement without causing irritation or photosensitivity.
• Collagen Synthesis Support — Anti-Aging at the Cellular Level: NAG plays a role in glycosaminoglycan synthesis, supporting the extracellular matrix and collagen network. This translates to improved skin firmness, reduced fine lines, and a more youthful appearance over time.
• Niacinamide Synergy — The Ultimate Brightening Duo: NAG and Niacinamide work synergistically to inhibit melanin transfer and reduce hyperpigmentation more effectively than either ingredient alone — making this combination a gold standard in brightening formulations.

Frequently Asked Questions (FAQ):

Q: What is N-Acetyl Glucosamine?
A: NAG (INCI: Acetyl Glucosamine) is an amino sugar derived from glucose. It is used in cosmetics for skin brightening, hydration boosting, and anti-aging benefits.

Q: What is the CAS number?
A: CAS No.: 7512-17-6

Q: What is the recommended usage rate?
A: Typically 1–5% in finished formulations. Dissolve in the water phase.

Q: Is it water-soluble?
A: Yes, NAG is water-soluble and should be added to the aqueous phase of formulations.

Q: What is the shelf life?
A: 24 months from manufacturing date when stored correctly.

Q: Is a Certificate of Analysis available?
A: COA available upon request.

Q: Can it be combined with Niacinamide?
A: Yes — NAG + Niacinamide is a well-known synergistic brightening combination that enhances melanin inhibition beyond what either ingredient achieves alone.
