What Is Biosaccharide Gum-1?

Biosaccharide Gum-1 is a natural gum produced through the fermentation of sorbitol, a sugar alcohol derived from plants like corn. Chemically, it is a chain of three linked sugars: α-L-fucose, α-D-galactose and α-D-galacturonic acid. This trio forms a flexible polymer that sits well on skin, creating a light breathable film.

The ingredient entered the cosmetic scene in the 1990s when formulators began exploring bio-fermented polysaccharides as gentler alternatives to synthetic thickeners. Because the fermentation process yields a highly purified product, Biosaccharide Gum-1 quickly found favor in brands focused on skin-friendly and eco-conscious formulas.

Manufacturing starts with plant-sourced sorbitol mixed with selected microorganisms in a controlled tank. As the microbes ferment the sorbitol, they secrete the gum. After fermentation, the mixture is filtered, heat-treated and spray-dried into a fine powder that re-disperses easily in water-based formulations.

You will most often see Biosaccharide Gum-1 in hydrating serums, sheet masks, soothing gels, anti-aging creams and leave-on moisturizers where it boosts comfort and glide while helping active ingredients stay in place.

Biosaccharide Gum-1’s Cosmetic Benefits/Uses

Biosaccharide Gum-1 offers one key function in skincare products.

As a skin-conditioning agent it forms a soft film that locks in moisture, leaving skin feeling smooth and supple. This film helps reduce water loss, calms temporary redness and gives formulas a silky touch that spreads evenly without stickiness.

Who Can Use Biosaccharide Gum-1

Biosaccharide Gum-1 is generally suitable for all skin types including dry, normal, combination, oily and sensitive because its lightweight film feels comfortable and does not clog pores. Extremely oily skin may prefer lower levels of the gum to avoid a dewy finish but most users find it breathable and non-greasy.

The gum is obtained from plant-derived sorbitol fermented by microorganisms so it contains no animal by-products. This makes it appropriate for vegetarians and vegans seeking cruelty-free options.

Current safety data show no known reproductive risks which means products containing Biosaccharide Gum-1 are considered compatible with use during pregnancy and while breastfeeding. That said this is not medical advice and anyone who is pregnant or nursing should have their healthcare provider review any skincare product before use just to be safe.

Biosaccharide Gum-1 does not make skin more sensitive to sunlight and can be worn day or night without increasing the need for additional sun protection beyond a normal broad-spectrum sunscreen.

Potential Side Effects/Adverse Reactions

Reactions to topical Biosaccharide Gum-1 vary by individual. The effects below are possible yet uncommon when the ingredient is used at standard cosmetic concentrations and most users will not experience them.

Mild redness or irritation in very sensitive individuals

Allergic contact dermatitis in people with a rare sugar or fermentation by-product allergy

Transient stinging if applied to freshly exfoliated or compromised skin

Product pilling when layered with high amounts of silicone or powder based makeup

If you notice any of the above while using Biosaccharide Gum-1 discontinue use and seek advice from a healthcare professional.

Comedogenic Rating

Rating: 0 (non-comedogenic)

Biosaccharide Gum-1 is a large, water-soluble polysaccharide that sits on the skin instead of seeping into pores and contains no oils or waxes known to trap sebum. Because it forms a breathable film and rinses away easily, it does not encourage blackheads or breakouts. People prone to acne can generally use products with this gum without worrying about clogged pores. If a formula that contains Biosaccharide Gum-1 also includes heavy oils or butters, those richer ingredients—not the gum—would be the more likely culprits for congestion.

Summary

Biosaccharide Gum-1 conditions skin by creating a thin, flexible veil that locks in water, calms fleeting redness and improves the glide of creams, gels and serums. It achieves these perks thanks to its fermented sugar chain that holds moisture and smooths the skin surface without heaviness.

The ingredient enjoys steady popularity among brands that focus on hydration and skin comfort, though it is not yet considered a mainstream buzzword like hyaluronic acid.

Current research and decades of cosmetic use show Biosaccharide Gum-1 to be very safe with a low risk of irritation or allergy. As with any new skincare product, it is wise to patch test first to make sure your skin agrees with the full formula.
