Claims20
A malodor counteractant formulation comprising:
- a malodor counteractant composition comprising metal oxide zinc ricinoleate nanocomposite particles;
- and
- a surfactant composition comprising a zwitterionic surfactant, a nonionic alkoxylated linear alcohol surfactant, or both.
A method for preparing metal oxide zinc ricinoleate nanocomposite particles, the method comprising a first stage and a second stage, and
- in the first stage:
- forming metal oxide zinc ricinoleate nanocomposite seed particles in a base solution;
- and
- in the second stage:
- growing the metal oxide zinc ricinoleate nanocomposite seed particles in the base solution to form the metal oxide zinc ricinoleate nanocomposite particles in the base solution.
A method for preparing a malodor counteractant formulation, the method comprising:
- combining a base solution containing metal oxide zinc ricinoleate nanocomposite particles with a surfactant composition, wherein the surfactant composition comprises a zwitterionic surfactant, a nonionic alkoxylated linear alcohol surfactant, or both.
