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.

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.

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.

A new thermoplastic silicone elastomer (TPSE) is shown here to improve scratch resistance, chip-off, feel, smoothness, gloss, and color in a nail polish formulation when compared with a formulation without TPSE. The new ingredient proves to be an interesting technology for optimizing nail polishes.

This article surveys patents and technical literature, principally from the past 10 years, to report advances in polymers used for dyeing hair, color retention,and hair lightening. Associative thickeners (anionic, cationic, amphoteric, nonionic, HASE, HEUR), nonassociative thickeners, and silicones are discussed.

In formulation, the key attributes of surfactants are conditioning, wetting, emulsification, and detergency. This article describes the features of surfactants that provide wetting properties in aqueous systems. Specifically, the properties of interest include surface tension reduction, HLB, molecular weight, branching, and level of ethoxylation. The choice of the best wetting agent depends upon chemical structure and the formulation.
