Is Rhizobian Gum natural?

Q: Is Rhizobian Gum natural?

Rhizobian Gum has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Polysaccharide gum excreted by Rhizobium bacteria during fermentation of a sugar feedstock; entirely biological. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

Yes. Polysaccharide gum excreted by Rhizobium bacteria during fermentation of a sugar feedstock; entirely biological.

INCI nameRhizobian Gum

FunctionFilm Forming · Hair Fixing

FeedstockProduced by fermenting a sugar substrate with Rhizobium…

How we scored it

Microbial fermentation polysaccharide; site rule = 1.0 (fermentation products).

What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Produced by fermenting a sugar substrate with Rhizobium bacteria, which secrete the gum. No petrochemical route is used commercially.

In plain English

A polysaccharide gum made by fermenting sugars with Rhizobium bacteria. Used to form films, fix hairstyles, and control the thickness of lotions and gels.

CosIng definition: Rhizobian Gum is the polysaccharide gum produced by the fermentation by Rhizobian
