What Distarch Phosphate does

Thickens water-based creams and lotions
Helps keep oil and water blended
Adds a smooth, silky skin feel
Helps a formula feel less greasy

Distarch Phosphate is made from starch taken from plants such as corn, tapioca or potato. The starch is treated with phosphate salts, which link the starch molecules together and add small phosphate groups along them. This process, often called cross-linking, helps the starch hold up better to heat, acid and the stress of mixing and pumping.

Formulators use it because it thickens water-based parts of a product and gives a smooth, soft body. That body helps a cream or lotion stay even and resist separating. It leaves a silky, slightly dry-feeling finish rather than an oily one, which is why it often appears in sunscreens that need to spread evenly and feel light.

Good for

Suits anyone who likes a light, smooth moisturizer or sunscreen feel.

Frequently asked questions

Is distarch phosphate safe for skin?

Distarch phosphate is widely used in cosmetics and is generally well tolerated. It is a starch-based ingredient, so it is not known to irritate most skin. As with any product, a patch test is a sensible step if your skin is very sensitive.

Does distarch phosphate clog pores?

It is not generally considered a pore-clogging ingredient. Starches are usually seen as light, water-based thickeners, and this one is common in lightweight moisturizers and sunscreens. How skin responds varies from person to person, so watching how your own skin reacts is always worthwhile.
