Additive having ultraviolet radiation protection for a laundry detergent
A method for treating a fabric for protection from ultraviolet radiation is disclosed which comprises the steps of dispensing a suspension of zinc oxide particles treated with an acid polymer into a washing machine during a time in which a fabric is being washed in the washing machine and mixing the treated zinc oxide particles and the fabric for the treated zinc oxide particles to bind to the fabric. Other methods for treating a fabric for protection from ultraviolet radiation are also disclosed.
1. A laundry detergent additive for incorporating ultraviolet radiation protection into a cellulose fabric comprising:
a suspension of zinc oxide particles each having a surface treated with the boronic acid functional groups of a boronic acid polymer.
2. A laundry detergent additive for incorporating ultraviolet radiation protection into a cellulose fabric comprising:
a quantity of zinc oxide particles with each of the zinc oxide particles having a surface; and
a quantity of boronic acid polymer, wherein the boronic acid functional groups of said polymer bind to the surface of the zinc oxide particles.
