Why formulators choose this ingredient

Polyglutamic Acid is more than another moisturising ingredient. Its combination of humectant and film forming properties makes it particularly useful when you want a formula to provide hydration while also creating a noticeably smooth and refined skin feel.

As a polyglutamic acid humectant for cosmetic formulations, PGA helps bind water while creating a lightweight film on the skin. In practical terms, this can make dehydrated skin feel softer, smoother and more cushioned while giving serums, gels and essences a more sophisticated finish.

It also gives formulators plenty of creative freedom. If you're looking to buy polyglutamic acid powder for skincare, the raw powder format lets you determine the supporting ingredients, texture and concentration instead of being restricted to a premixed finished serum.

Does this ingredient suit me?

It’s best for:

• Dry and dehydrated skin
• Skin that feels tight or lacking in moisture
• Dull skin where a plumper, fresher appearance is desired
• Mature skin where dehydration lines are a concern
• Lightweight hydration formulations
• Hydrating serums, gels and essences
• Moisturisers and emulsions
• Formulas designed for a smooth, cushioned skin feel
• DIY skincare creators
• Professional cosmetic formulators

Frequently asked questions

What is Polyglutamic Acid?
Polyglutamic Acid, commonly known as PGA, is a biopolymer composed of glutamic acid units. In cosmetics, it is valued primarily as a humectant, film former and skin conditioning ingredient that helps support moisture retention.

What is gamma Polyglutamic Acid?
Gamma Polyglutamic Acid, or γ PGA, refers to the gamma linked form of Polyglutamic Acid. This pure polyglutamic acid powder for cosmetics is valued for its affinity for water and its ability to form a lightweight film that supports moisture retention.

Is Polyglutamic Acid the same as Hyaluronic Acid?
No. They are different molecules, although both are widely used in hydration focused skincare. Hyaluronic Acid and Sodium Hyaluronate are glycosaminoglycans, while Polyglutamic Acid is a polymer of glutamic acid. PGA's film forming properties make it particularly useful for helping retain moisture at the skin's surface.

Can I use Polyglutamic Acid with Hyaluronic Acid?
Yes. Polyglutamic acid powder with hyaluronic acid can be incorporated into a thoughtfully designed formula where the two humectants provide complementary hydration and moisture retention properties.

What can I make with Polyglutamic Acid Powder?
It can be used in hydrating serums, essences, gels, toners, ampoules, moisturisers, lotions and other water based or emulsified cosmetic products. This versatility makes water soluble polyglutamic acid powder for cosmetics useful for everything from simple hydration products to more sophisticated formulations.

How much Polyglutamic Acid should I use?
For this supplied raw material, the recommended usage information is 1 to 5% in emulsified or water based products. The ideal percentage depends on the desired texture and complete formulation, so stability and compatibility testing are recommended.

Can I make a simple PGA serum?
Yes. This polyglutamic acid powder for face serum can be used with the supplied DIY method. Add 1.5g, or 2 level scoops, to 48.5 mL of distilled water. Allow it to hydrate for 1 to 2 hours, stirring occasionally, until it develops into a clear, watery serum. This makes approximately 50 mL.

Why does my PGA form strands while mixing?
Soft, elastic strands may stick to the scoop while the powder is hydrating. This can occur because of PGA's film forming nature and does not necessarily indicate a problem with the powder.

Is Polyglutamic Acid suitable for sensitive skin formulations?
PGA can be incorporated into formulations intended for a variety of skin types. However, tolerance depends on the complete finished formula. Patch testing and appropriate formulation testing are recommended.

Can professional cosmetic formulators use this powder?
Yes. As a professional grade polyglutamic acid powder, it can be used when developing serums, gels, essences, lotions and other hydration focused cosmetics. With sizes from 50g to 1kg, you can choose an amount suited to experimentation, small batch formulation or larger production requirements.

Ingredients

Includes Polyglutamic Acid.

Polyglutamic Acid is a water soluble biopolymer used in cosmetic formulation for its humectant and film forming properties. It helps bind and retain moisture while creating a smooth, cushioned feel on the skin, making it particularly useful for modern hydration focused skincare.

Professional tip

When using polyglutamic acid powder for skincare formulations, avoid introducing a large amount of powder into water all at once, as this can encourage clumping. For more advanced formulations, gradually disperse the powder and consider pre wetting it before incorporation. Where possible, add PGA during the cool down phase at 40°C or below, rather than exposing it to prolonged high temperatures.

For a simple DIY serum, add 1.5g, or 2 level scoops, to 48.5 mL distilled water and allow 1 to 2 hours for hydration, stirring occasionally. Soft, elastic strands during mixing can be normal due to PGA's film forming properties.

When developing commercial formulations, always perform stability, compatibility and preservation testing on the complete finished product.
