Opposing Forces: Water Resistance vs. Rheology Control: An Exploration*
Water resistance is desired across a range of cosmetic categories. Two materials used to impart this property, however—the emulsifier system and film-forming polymer—are known to change the rheology of formulas. This study assessed the impact of these ingredients on rheological and texture profiles.

TEST-Broad Spectrum Antimicrobial Protection with 100% Natural Spectrastat™ Technology
One longtime favorite ingredient for use in both health food and cosmetics is maca, the pulverized root of a Peruvian plant that grows high in the Andes. Maca has been cultivated for thousands of years, most notably by the Inca, who valued it as a food crop. Beyond its use as a complex starch in health foods, maca’s fine consistency allows for the easy adjustment of viscosity in creams and lotions

Blue Sky Thinking: Star Polymer Aligns Clarity with Viscosity for High-perfume Surfactant Systems
Building viscosity and clarity in surfactant systems, especially those that are sulfate-free and have high fragrance loads, is challenging. In response, a new six-armed nonionic associative thickener was developed that effectively bridges many small micelles to create larger, bridged structures that improve viscosity, while retaining clarity.

Yield Stress Measurements for Personal Care Part II: Methods
The previous article defined yield stress and explained how to calculate the amount needed for a given application. Here, methods for measuring yield stress are compared by determining the values of two materials: a non-thixotropic acrylates copolymer solution, and a thixotropic body wash. The results provide recommendations for methods in terms of relevance, exactness and robustness.

Balancing Texture with Electrolyte Resistance for Improved Thickening
Described here are two acrylic rheology modifiers for novel thickening properties in formulations. A pre-neutralized carbomer is shown to impart a lighter, smoother texture than traditional carbomer while increasing process flexibility. In addition, a new associative acrylate/C10-30 alkyl acrylate crosspolymer exhibits thickening in high electrolyte media, acts synergistically with surfactants, and facilitates the dispersion of fillers.

Formulating Lip Gloss
Lip glosses combine the properties of color cosmetics and lip balm to offer high shine, lip enhancement and pleasantness, accompanied by protection and soothing benefits. To offer these properties, lip glosses must incorporate a complex blend of oils, waxes, thickeners and tackifiers. Various modern technologies allow the formulator to assemble sensorially enchanting lip glosses.
