Sodium Silicate

Sodium silicate is an inorganic salt derived from silicon dioxide. In cosmetics, it often acts as a binder, helping to hold ingredients together in a product. It can also form a thin film on the skin or hair, providing temporary tightening or smoothing effects.

Whether it can help visible signs of aging — fine lines, wrinkles, loss of firmness, or photoaging.

Sensitization i0.3 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

Systemic exposure i0.1 / 4

Whether it has meaningful potential to be absorbed into the body at levels that may matter biologically. Most cosmetic ingredients score low unless there is known concern or high exposure.
