Title: Innovations of Ajay Kanubhai Suthar in Cosmetic Technology

Introduction

Ajay Kanubhai Suthar, based in Lexington, KY, is a renowned inventor with an impressive portfolio of 31 patents. His work primarily focuses on developing novel cosmetic ink compositions, which incorporate advanced materials to enhance their properties and applications in the cosmetics industry.

Latest Patents

Among his latest innovations is a patent for a stable cosmetic ink composition. This formulation includes a particulate material, a (meth)acrylic acid homopolymer or its salt, and a rheology modifier. The particulate material within this composition boasts a Particle Size Distribution D50 that ranges from about 100 nm to about 2,000 nm. The (meth)acrylic acid homopolymer is designed with a weight average molecular weight of less than approximately 20,000 daltons. The rheology modifier is selected from various options, such as alkali swellable emulsion polymers and their hydrophobically modified versions. Importantly, this cosmetic ink composition achieves a first dynamic viscosity exceeding 1,100 cP at a shear rate of 0.1 sec at 25° C, coupled with a second dynamic viscosity of less than 100 cP at a shear rate of 1,000 sec at the same temperature.

Another notable patent is for a heterogeneous cosmetic ink composition specifically tailored for inkjet printing applications. This composition maintains a particulate material, coupled with a polymeric dispersant having a weight average molecular weight of less than about 20,000 daltons, and a polymeric rheology modifier. Remarkably, this formulation can undergo controlled syneresis, resulting in a weak colloidal gel phase alongside a particle-lean, low viscosity phase that allows for printing without the need for interventions like agitation or mixing.
