Product Description

Sodium polyglutamate (also called PGA) is a water-soluble high molecule polymer produced by microbial fermentation. Structurally it is the glutamic acid linked by amide bonds. There are a large quantity of hydrogen bonds between and within the molecules of PGA contributing to the excellent moisturizing capability of the material.Using PGA and HA together can greatly increase the action time of HA and bring about smoother skin feeling by decreasing the sticky feeling of HA.

Basic Information

INCI Name: Sodium Polyglutamate

CAS No.: 28829-38-1

Appearance: White to off-white powder or particles

Assay: ≥92%

Molecule Weight: PGA-HMW (>700kDa)

PGA-LMW (70kDa~150kDa)

PGA-Oligo (<10kDa)

Features

PGA-HMW: Long-lasting Moisturization

1. Moisturizing skin for longer hours

PGA has very strong hydration ability because of large number of hydrophilic groups along the molecule chain of PGA.

The transepidermal water loss (TEWL) experiment found that the moisturizing effect of PGA-HMW is better than that of hyaluronic acid and collagen

2. Unique smooth skin feeling

PGA-HMW can bring very smooth skin feeling, water-skiing touch feel, and can effectively reduce the viscosity caused by hyaluronic acid.

PGA-LMW: Skin moisturizing and healthy whitening

1. Healthy whitening

Tyrosinase is a key enzyme for the production of melanin in human skin. Studies found that PGA-LMW can mildly inhibit the function of tyrosinase and delay the formation of pigmentation. Brightening skin more gentle, PGA-LMW can achieve the efficacy of skin healthy brightening.

2.Increasing and Maintanining HA of Skin

Hyaluronic acid (HA) is a natural component in human skin, but hyaluronidase (HAase) also exists in the skin. PGA-LMW can inhibit the activity of HAase, thus improve the stability and content of HA in skin.

PGA-oligo : Improving Nutrient Supply

1. Promote the production of NMF in inner skin

Natural moisturizing factor (N.M.F) is a variety of hygrophilic substances naturally existing in the cuticle of human skin, including 40% amino acid, 12% pyrrolidone carboxylic acid, 12% lactate, 7% urea and so on. PGA-oligo can improve the content of N.M.F, and then improve the skin's water binding force, which is beneficial to elimination of early skin wrinkles.

2. Energize your skin

With low molecular weight, less than 10kDa, PGA-oligo can reach the skin base and make the skin full of water.

Meanwhile, PGA-Oligo can conrol the free radical, repair photoaging, and restore youthful skin appearance.

Application

PGA can be used in facial mask, cream, emulsion, essence, facial cleanser, shampoo, hair care products etc.

Recommanded dosage: 0.1%-1%

Add PGA in aqueous phase, after being dissolved completely and then emulsified.
