A water-soluble cosmetic polymer for long-lasting hydration, softer skin feel and moisture-retaining product concepts. Sodium Polyglutamate is the sodium salt of a glutamic-acid homopolymer used in serums, creams and masks. This white powder is for measured formulation and bench testing—not direct raw-material application.

Supports formulas designed for longer-lasting hydration and a smoother, more supple-looking skin surface. [R4–R6]
Useful in water-based serums, creams, masks and body-care products where a hydrophilic polymer can support moisture retention. [R4–R5]
Molecular-weight grade matters: lower- and higher-MW Sodium Polyglutamate versions are sold for different formulation goals. [R2–R5]
Choose a paid trial size for bench evaluation, or request a bulk quote for commercial supply.

Key Benefits

Long-lasting hydration support: Its hydrophilic polymer chain can bind water and help create a moisture-retaining environment at the skin surface. A 2025 high-molecular-weight γ-PGA study support its use in hydration-focused development. [R4–R6]

Softer, smoother-looking skin: Higher-molecular-weight cosmetic grades are positioned for improved smoothness and softness, making Sodium Polyglutamate useful in formulas designed to reduce a dry, tight skin feel. [R4]

Barrier-support product concepts: In a reconstructed-skin study, a specific high-molecular-weight γ-PGA material increased several markers associated with barrier and hydration function. This supports a barrier-care development angle. [R6]

Flexible hydration architecture: Different molecular-weight grades allow formulators to tune surface feel, viscosity contribution and hydration positioning rather than treating every Sodium Polyglutamate powder as interchangeable. [R2–R5]

Why Formulators Choose Sodium Polyglutamate

Adds a biofermented amino-acid-polymer option for hydration-focused formulas.
Complements humectants such as glycerin and sodium hyaluronate in layered hydration systems.
Fits serums, emulsions, masks and body-care systems. [R4–R5]

Typical Applications

Hydrating serums: Water-based or gel-serum systems for moisture retention and supple skin feel.
Creams & lotions: Daily moisturizers, barrier-support creams and body-care emulsions.
Facial masks: Sheet-mask essences and other hydration-focused mask formats.
Eye / targeted hydration products: Formulas focused on dryness, smoothness and a plumper-looking surface.
Hair & scalp care: Conditioning/hydration concepts where a water-compatible polymer fits the system.

Quick Formulation Guide

Formulation Question	Buyer Guidance
Typical use level	about 0.05–1% . [R7–R8]
Dissolution	Water soluble. Add with good agitation and allow full hydration; avoid clumps. [R7]
Molecular-weight choice	MW can change film feel, smoothness, viscosity contribution and finished-system behavior. [R2–R5]
Compatibility	Evaluate total humectant load, electrolytes, rheology, preservation and sensory target in the complete formula.
Scale-up	Confirm MW/viscosity grade, polymer-content basis and current specification before pilot or production scale.

Why Source From Us

Start with samples scale to bulk orders – one supplier from trial to production: Validate with lab samples, then scale to commercial volumes – same quality, same team. No re-qualification, no project delays.
Formulation support that actually helps – not just a data sheet: We give you hands-on guidance on solubility, temperature, pH, and compatibility. A real formulation partner, not a catalog.
Reliable supply chain – consistent quality, on-time delivery, batch after batch: Own manufacturing facilities plus long-term partnerships with audited upstream producers ensure batch-to-batch consistency. Full documentation with every shipment. No "sample passes, bulk fails"
Export-ready documentation – compliance, customs, cleared：Complete technical documentation packages – COA, MSDS, TDS, stability data – batch-specific and regulatory-ready. We handle the paperwork so your compliance and procurement teams can focus on formulation

Recommended Ingredient Pairings

Recommended Ingredient	Why It Pairs Well	Product Concept	Compatibility Note
Sodium Hyaluronate	Adds complementary polymer hydration.	Layered hydration serum	Control polymer load, viscosity, tack and pilling.
Ectoin	Adds hydration and skin-comfort support.	Barrier-comfort serum or cream	Check electrolyte load, pH and full-formula stability.
Glycerin	Provides a familiar humectant base.	Daily hydrating toner or serum	Balance total humectant level to avoid tack.
Niacinamide	Broadens barrier and tone-support positioning.	Multi-benefit daily serum	Choose a pH suitable for the complete active system.
Panthenol	Adds conditioning and comfort for skin or hair.	Soothing moisturizer or hair serum	Validate feel, preservation and final rheology.

Scientific Evidence Snapshot

Sodium Polyglutamate is a glutamic-acid homopolymer sodium salt. [R1] In a 2025 study, a specific high-MW γ-PGA material increased several barrier- and hydration-associated markers in keratinocytes and reconstructed skin; 1% was tested in the reconstructed-skin model. [R6] This supports hydration and barrier-care development.
