Sugar and the Quest for Sulfate-Free Formulations

Many approaches have been tried over the years to eliminate lauryl sulfates and lauryl ether sulfates from personal care formulations, most of which have not been cost-effective. This article discusses a new class of patented anionic products based upon sugar raw materials.

A Surfactant/Biopolymer Stabilizer for Emulsions

An emulsifier/biopolymer system using a mixture of nonionic surfactants and two biopolymers was developed. The surfactants provide effective steric stabilization against coalescence, whereas the biopolymers provide a high residual viscosity and yield value, thus providing stability against creaming. The mechanism of stabilization is discussed in terms of the synergy between the two biopolymers.

Enabling Advanced Emulsions in Microchannel Architecture

An innovative emulsification technology is demonstrated, which can be applied to surfactant-free emulsions and has the propensity for stimuli-responsive behavior. The technology can be used to allow previously difficult product formulations with shear-sensitive materials and controlled, droplet size distribution.

Properties of Surfactants: Detergency

Determining the soils to remove during the cleansing of hair is critical to the understanding of detergency. Here, the author describes how formulators can choose a detergent based on its efficiency specific to the types of oils found commonly on hair.

Anionic/Cationic Complexes

Understanding the interactions of surfactants is important to optimizing their properties in formulations. The author describes how the anionic/cationic interaction is critical to properties such as foam, viscosity, conditioning properties and minimal irritation.

Properties of Surfactants: Emulsions

The metastable nature of two insoluble materials is critical to understanding the nature and performance of emulsions. This metastability and the requirement that the emulsion be cosmetically appealing offer unique challenges to the formulator.

Making Up the Psyche

This issue highlights Mendrok-Edinger et al.’s quest to find the best butyl methoxydibenzoyl methane stabilizer for sun care; Farwick et al.’s update of ceramide identification, synthesis, function and nomenclature; and finally, Arif’s discussion supporting the smart use of sulfates in formulations. There’s a little something to stimulate everyone’s psyche in this issue.

Sulfate vs. Sulfate-free: Information to Make a Choice

In the present article, the author considers factors for sulfate vs. sulfate-free formulating, including cost, foam and viscosity. In addition, two test formulations with and without sulfates are compared. The author concludes that little sound science exists to support the current “sulfate-free” market trend, especially when considering the potential benefits sulfates can impart in formulations.

Extra-mild Sulfosuccinate Surfactant

With low skin and eye irritation properties, this surfactant works in mild shampoos, detanglers, facial cleaners and anti-acne formulations.

Surfactants from Coconut Oil, Corn Syrup

Colonial Chemicals has derived eco-friendly surfactants from coconut oil and corn syrup to launch its latest product series for personal care applications.

Surfactant vs. Gemini Surfactant

Industry expert Tony O'Lenick examines the difference between these two types of surfactants or surface acting agents.

McIntyre Awarded Patent on Surfactant Compositions

McIntyre Group was awarded U.S. Patent No. 7,282,524 for its alkanolamide emulsion technology.

Surfactant vs. Silicone Surfactant

Industry expert Tony O'Lenick explores the differences between surfactants and silicone surfactants.

NaCl vs. SLS Solutions

Industry expert Tony O'Lenick explains the difference between NaCl (salt) solution and a solution of sodium lauryl sulfate (SLS).
