Description

Polyglutamic Acid - Next-Generation Super-Moisturizer

Polyglutamic Acid (PGA) is a revolutionary biopolymer obtained through bacterial fermentation, recognized as one of the most powerful hydrating agents discovered to date. With a water retention capacity superior to hyaluronic acid, PGA not only hydrates deeply but forms a fine protective film on the skin surface that prevents moisture evaporation and protects the natural hyaluronic acid reserves of the epidermis by inhibiting enzymatic degradation.

Ingredients: Sodium Polyglutamate.

Characteristics

Appearance: White crystalline or granulated powder, almost odorless.
Solubility: Fully water-soluble, dissolves easily in water.
Quality: Ingredient obtained by fermentation, biodegradable.

Efficacy tests - specialized literature

Efficacy has been demonstrated through comparative studies and laboratory tests:

Moisture Retention: Comparative tests have shown that Polyglutamic Acid maintains a hydration level even higher than hyaluronic acid 12 hours after application.
Hyaluronidase inhibition: Polyglutamic Acid inhibits the activity of the hyaluronidase enzyme, protecting the structure of the dermis.
Natural Moisturizing Factors (NMF): Polyglutamic Acid significantly stimulates the internal production of lactic acid and PCA, strengthening the skin barrier.

Main Properties

Intense Hydration: Retains massive amounts of water and increases the level of natural moisturizing factors (NMF) in the skin; more hydrating than hyaluronic acid.
Hyaluronidase Inhibition: Can inhibit the activity of hyaluronidase (the enzyme that degrades natural hyaluronic acid), thus protecting the skin's hydration reserves.
Plumping Effect: Fills fine lines and dehydration wrinkles, creates a protective film that seals hydration into the skin, providing a smooth and "full" appearance.
Elasticity Improvement: Stimulates natural moisturizing factors (NMF) such as lactic acid and pyrrolidone carboxylic acid (PCA).
Silky Finish: Forms a non-sticky film that offers an immediate sensation of softness and an aesthetic shine.

Usage recommendations

Cosmetic ingredient. General dosage: 0.1% - 1.0%
Suitable for the preparation of various cosmetic products for face, body, and hair care. It is ideal for products intended for dehydrated, mature, or skin lacking elasticity. It improves the texture of creams and the post-application sensation. It is suitable for hair products because it protects the hair fiber, hydrates dry scalp, maintains hydration, and reduces the effects of external aggressions.

Applications

High-End hydrating serums and lotions
Moisturizing and anti-wrinkle creams for any skin type.
Sheet-type or gel facial masks.
Eye area care products, blurring fine lines.
Makeup primers for a smooth finish.
After-sun products for barrier restoration.
Ultra-hydrating body creams and milks; hand creams.
Leave-in treatments for protection against hair dehydration.
Hair balms, conditioners, and masks.

Formulation Guide

Procedure: Dissolves in the aqueous phase at room temperature. Can be premixed in glycerin or propanediol for easy incorporation.
Temperature: It is thermally stable within normal cosmetic processing ranges.
pH Range: Optimal between 4.5 and 8.0. At a pH below 4.0, the product may precipitate.
Technical tip: Works synergistically with Hyaluronic Acid; using both in the same formula offers multi-level hydration and they work excellently together.

Frequently Asked Questions (FAQ)

Can it be used in water-based serums without emulsifiers?
Yes, it is perfect for clear aqueous serums. The powder dissolves completely and does not require special suspending agents.

Is it sticky on the skin?
In general, Polyglutamic Acid provides a smooth and silky feel, being less sticky than certain forms of Hyaluronic Acid at similar concentrations.

Safety in Use

Profile: It is a safe, biocompatible, and biodegradable ingredient without major sensitizing potential.
Precautions: The product is intended exclusively for cosmetic use. Do not ingest. Avoid direct contact with eyes in pure form.
Storage: Store in the original packaging, in a cool place and away from direct light. The container must be hermetically closed after each use, as the powder can be hygroscopic (absorbs moisture from the air).
