Ingredient Profile—Polysorbate 20

Polyoxyethylene (20) sorbitan monolaurate (INCI: Polysorbate 20), is a ubiquitous nonionic surfactant employed in the formulation of countless cosmetic and personal care products.

Cassia-derived Polymers for Improved Silicone Deposition in Hair

The Lubrizol Corp.’s Noveon Consumer Specialties has introduced cassia-derived polymers for improved deposition, enhanced conditioning and distinctive sensory attributes in hair cleansing formulations.

Glyceryl Stearate Citrate Emulsifier Derived From Rapeseed

At In-cosmetics in Milan, Dr. Straetmans GmbH will launch a glyceryl stearate citrate emulsifier derived from rapeseed oil rather than palm oil.

Photostabilization of Retinol and Retinyl Palmitate by Ethylhexyl Methoxycrylene

This study examines the photostability of retinol and retinyl palmitate, finding they break down rapidly when exposed to UV radiation in the 290–400 nm range. This severely reduces their concentrations in finished formulations. However, when combined with ethylhexyl methoxycrylene, these retinoids are shown to be protected against photodegradation, thus preserving their concentrations both during the manufacturing process and following application to the skin.

Shikakai, Desert Date and Gypsophila for Foam Boosting and Cleansing

Crodarom has launched a natural foam booster blend based on shikakai, Balanites aegyptiaca (desert date) and gypsophila (baby's breath).

Benefits of Borneo Camphor-derived Hydropes for 'Natural' Formulations

Alpha-pinene, typically derived from pine trees, is also a by-product of the paper manufacturing process. The material is a source of low-toxic and naturally based isobornyl ethers, from which a new hydrotrope, dipropylene glycol isobornyl ether, was developed.The present study examines the unique dispersion and solubility properties of this material, among other benefits, and its application in cosmetics.

Film Former for Water-resistant Color Cosmetics

Interpolymer has introduced a water-resistant, quick-setting film former for color cosmetic formulations.

Coconut-derived Hydrotropes for Natural Cosmetics

Colonial Chemical Inc. has launched two vegetable-derived replacements for petroleum-based hydrotropes to formulate natural personal care products.

Low-surfactant Emulsification: Optimizing Formulas and Conserving Resources

Understanding the process variables that occur during emulsion manufacturing can assist formulators in preventing production inconsistencies as well as selecting the most effective surfactant blend for a given purpose. This in turn reduces the amount of surfactant required without affecting emulsion quality or stability, thus saving resources and even improving product quality, as the present article describes.

Silicone Copolymer for Wetting, Emulsifying in Hair Care

NuSil Technology LLC has launched a water-soluble, silicone-glycol copolymer that functions as a wetting agent and emulsifier in hair care formulations.

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.
