Biosaccharide Gum-1

What is Biosaccharide Gum-1?

Biosaccharide gum-1 is a large sugar molecule made by fermentation. The Cosmetic Ingredient Review panel describes it as a fermentation gum derived from sorbitol, built from repeating units of three sugars: fucose, galactose and galacturonic acid.

Because it’s made by microbes rather than pulled from a plant, it sits in the same family as other fermentation gums such as xanthan gum. You’ll find it in moisturizers, serums, eye creams and some makeup, usually in the middle or lower half of the ingredient list.

What does Biosaccharide Gum-1 do?

• Conditions skin. Its official job is skin conditioning. It leaves a thin, smooth film that makes skin feel soft and moisturized.
• Improves the feel of a formula. It can give a serum or cream a silky slip without an oily finish.

That’s the realistic picture. You may see claims about soothing or long-lasting hydration on packaging. Those are a brand’s claims about its own formula, and the ingredient name alone doesn’t predict them.

Who is Biosaccharide Gum-1 for?

It suits most skin types. People with dry or dehydrated skin may like the smooth, cushioned feel it adds, and it doesn’t feel greasy on oily skin. The safety review reported its use in hundreds of formulations, including leave-on products, and concluded it is safe as used.

If you have very reactive skin, the rest of the formula, such as fragrance or strong actives, is more likely to matter than this ingredient. Patch-test new products as usual. Because it’s a conditioning ingredient rather than an active, it doesn’t need the slow introduction that exfoliating acids or retinoids do.

What to pair Biosaccharide Gum-1 with, and what to avoid

It often appears with other humectants, such as glycerin and hyaluronic acid, and it fits easily into a layered hydration routine. There’s nothing you need to avoid with it.
