Hydroxypropyl Guar
What Hydroxypropyl Guar is & what it does
Hydroxypropyl Guar is a modified, water-soluble derivative of guar gum, a polysaccharide from the guar bean. It works as a thickener, film former, and texture enhancer, giving lotions and gels a smoother, more cushioned slip. It is widely used in sunscreens and cleansers to stabilize the formula and improve spreadability. It is generally considered a mild, well-tolerated functional ingredient.

It helps thicken and stabilize the formula and gives a smoother, more cushioned slip when you spread the product. This improves spreadability and feel but does not itself add sun protection.
