Biosaccharide gum-4 is a chemical compound, a deacetylated anionic polysaccharide with a high molecular weight and branched structure, a product obtained from sorbitol by a bacterial fermentation process in which trisaccharides of galacturonic acid, rhamnose, L-fucose, D-galactose are directly or separately involved.

The name describes the structure of the molecule.

• Bio indicates that the component is derived from a biological source.
• Saccharide refers to sugars or carbohydrates, indicating that the molecule has a sugar-based structure.
• Gum:  the substance has a gummy or viscous consistency.
• -4:  a specific variant or form of the compound.

Function of Components

Biosaccharide Gum-4 is known for its moisturizing and soothing properties. It is used in skincare products for its ability to bind water and enhance skin hydration. Additionally, it may provide anti-pollution benefits by forming a protective layer on the skin that helps shield it from harmful environmental agents.

Description of Raw Materials Used in Production.

• Saccharides: primarily derived through fermentation.
• Water: used in the fermentation and extraction process.
• Fermentation Agents: for creating the biopolymer through fermentation.

Step-by-step Summary of Industrial Production Process.

• Preparation and Fermentation. Saccharides are prepared and then fermented using specific microorganisms.
• Extraction. The biopolymer (gum) is extracted from the fermented solution.
• Purification. The product is purified to remove any impurities.
• Drying. The gum is dried to remove residual water.

Form and Color.

Biosaccharide Gum-4 typically appears as a viscous, colorless liquid or a fine powder and may have a color ranging from white to pale yellow.

What it is used for and where

Cosmetics

Film-forming agent. It produces a continuous ultra-thin film with an optimal balance of cohesion, adhesion and stickiness on the skin or hair to counteract or limit damage from external phenomena such as chemicals, UV rays and pollution.

Skin conditioning agent - Miscellaneous. This ingredient has the task of modifying the condition of the skin when it is damaged or dry by reducing its flakiness and restoring its elasticity.

Antimicrobial agent. This ingredient is able to suppress or inhibit the growth and replication of a broad spectrum of microorganisms such as bacteria, fungi and viruses by making the stratum corneum temporarily bactericidal and fungicidal.

Trade name:  Pollustop

CAS:   905593-86-4

Commercial applications:

Cosmetic Industry. Biosaccharide Gum-4 is used as an active ingredient in various skin care products owing to its moisturizing and soothing properties.

Sun Protection Products. It is utilized in sun-care products for its ability to form a film on the skin, contributing to providing some protection against UV rays.

Skin Care Products. Used in creams, lotions, and serums for its humectant properties that help to keep the skin moisturized.
