A compilation of Articles about Understanding Silicone Chemistry and Formulation Technology

Preface
This work is a compilation of articles arranged in several sections designed to allow the cosmetic formulator to search for information that will aide in formulations. It is the author’s intention to add new articles as that become available to include the most recent information. Each chapter can stand alone, meaning it will contain enough information to allow the reader to understand the topic by reading only that chapter. This results in some information being repeated, but having repetition in chapters enforces the important concepts and reading stand-alone articles in more efficient than having the read the entire work.
As the great Enrico Fermi stated:
“Never underestimate the joy people derive from hearing something they already know.”
Table of Contents
The Basics
It is recommended that the reader look at the chapters in this section, most importantly the first three, since they cover the basic concepts that will apply to all additional chapters. The reader is challenged to ask, why is this particular silicone in the formulation.
Chapter 1: Why use silicone in personal care applications Part 1 – Dimethicone Soluble
Polymers
Chapter 2: Why use silicone in personal care products Part 2 – Water Soluble Silicone Polymers
Chapter 3: Why use silicone in personal care Applications Part 1 – Oil Soluble Silicone Polymers
Chapter 4: Understanding Silicone – Overview (a large file)
