His record includes 1 patent and professional associations with Conopco, Inc. and Unilever N.V.

Latest Patents

Ruddock’s patent, “Aerosol product comprising an aqueous composition,” describes a nozzle designed to produce a spray that feels less wet. The nozzle uses multiple inlet channels leading into a swirl chamber and an outlet orifice. The patent specifies that the combined widths of the inlet channels should be less than the swirl chamber’s diameter and at least 1.5 times the outlet orifice’s diameter. It also describes an outlet orifice of at least 0.3 mm and short inlet channels, such as channels shorter than 0.5 mm.

The design is intended to be especially suitable for compositions with low volatile organic compound content and formulations containing a significant proportion of water. These characteristics make the invention relevant to aqueous and aqueous-alcoholic aerosol products, including deodorant sprays.

Career Highlights

Ruddock’s listed company associations include Conopco, Inc. and Unilever N.V. His patent reflects an engineering focus on the relationship between aerosol dispenser components and the qualities of the resulting spray.
