HYDROLYZED RHIZOBIAN GUM.

Valuable CAS - / FILM FORMING

Hydrolyzed Rhizobian Gum is a natural polysaccharide that creates an ultra-thin, flexible film on the skin. This film provides significant moisture binding, delivering hydration and a smoothing effect, while also offering a perceivable tightening sensation, particularly beneficial for delicate areas.

Film-forming agent Moisturizer/humectant

Science

Operating primarily as a film-forming agent, Hydrolyzed Rhizobian Gum creates an invisible, elastic layer upon application to the skin. This continuous film actively binds water, enhancing skin hydration and preventing transepidermal moisture loss. Its inherent elastic properties also contribute to a mechanical lifting effect, most noticeably in the eye contour area, while simultaneously improving the sensory aesthetics of formulations and potentially offering a slight cooling sensation from evaporative action.
