Non-hazardous polysaccharide. No GHS classifications. No skin, eye, or respiratory hazards at any relevant concentration. Generally recognized as safe (GRAS) for food use by FDA.

Xanthan gum is a high-molecular-weight polysaccharide produced by fermentation of the bacterium Xanthomonas campestris. In car care products it serves as a thickener and rheology modifier, giving water-based formulas a controlled viscosity that helps them cling to surfaces during application. It is non-toxic, readily biodegradable, and carries no GHS hazard classifications. EPA Safer Choice listed.
