Indie Sleaze, Brat Summer ... How Market Trends Affect Formula Basics: 7 Experts Weigh In

We often explore how market trends influence product concepts. Less often do we focus on their impact on preservation, rheology and other formula basics. As such, we reached out to industry insiders for their take; here, seven experts weigh in.

Amphoteric Anionic Interactions

A study of interactions between anionic surfactants and amphoteric surfactants in solution demonstrates that betaines and anionic surfactants interact to have positive effects on viscosity, foam and the salt curve.

Ingredient Profile—Carbomer

Carbomers, a family of crosslinked acrylic acid polymers, are essential ingredients in numerous products, including: pharmaceuticals; cosmetics and personal care items; household, industrial and institutional care products; printing inks; adhesives and coatings. This column will explore the chemistry and properties of carbomers that have earned them this well-deserved reputation.

Polymers in Personal Care

Polymer use began in the 1800s with cellulose derivatives, the vulcanization of rubber, and styrene synthesis; but in reality, it started more than four million years ago with the formation of DNA and proteins. Polymers are a diverse class of chemistry. By definition, they are large molecules made up of chains or rings of linked monomer units—simple reactive building blocks. Smaller molecules or monomers are combined to form polymers that possess a characteristic chain structure of multiple repeating units that can be related or different.
