Title: The Innovative Contributions of Padmakumari J Varaprath

Introduction

Padmakumari J Varaprath is a notable inventor based in Midland, MI (US). He has made significant contributions to the field of silicone emulsions and hair treatment compositions. With a total of 13 patents to his name, Varaprath's work has had a considerable impact on various industries.

Latest Patents

One of his latest patents is a method of manufacturing silicone emulsions. This method describes the process of creating an emulsion by forming a mixture that includes a polysiloxane and a primary nonionic surfactant with an HLB value ranging from 10 to 19. The process involves adding a first portion of surfactant-free water gradually in a series of incremental steps. Following this, a secondary nonionic surfactant with an HLB value of 1.8-15 is added. The mixture is stirred until the particle size of the polysiloxane is between 1-100 microns. A second portion of water is then added to achieve a total water content of 25-65 percent by weight.

Another significant patent involves hair fixatives, which introduces a new composition of matter that is an aminofunctional silicone resin. This resin is formed through the reaction of an aminofunctional silane and a silicone resin. The patent also discloses a hair treating composition that combines a film-forming material with a solvent. The film-forming material is the aminofunctional resin, and a method for imparting curl retention to hair using this resin is further described.
