Soybean-derived Emulsifier/Thickener

Dow Corning has launched a sustainable emulsifier and thickener derived from soybean oil.

A New Thickener/Stabilizer Technology

This article describes a new synthetic thickener/stabilizer technology that provides these attributes. Although there area variety of raw materials used to thicken personal care products, few are sufficiently versatile to offer effective thickening, gelling and suspending properties for a wide variety of applications.

Rheology Modifier for Textures in Cleansing Formulations

Rhodia has launched a rheology modifying polymer for personal cleansing solutions.

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.

Liquid Polymer for Sensorial Benefits and Electrolyte Tolerance

The Lubrizol Corporation’s Noveon Consumer Specialties has introduced a polymer that provides sensory properties and electrolyte tolerance.

Water-soluble Cellulose-derivatives for Hair, Skin Care

AkzoNobel Global Personal Care is launching a line of environmentally friendly polymers for hair and skin care at In-Cosmetics in Milan.

Ingredient Profile: PEG-150 Distearate

Cosmetics & Toiletries magazine has added the new column, “Ingredient Profile,” to its regular monthly lineup. Written by expert Michael J. Fevola, PhD, of Johnson & Johnson, it is intended to provide formulators with information about the chemistry and manufacture of common cosmetic raw materials and how their key properties impact formulations.

Improving Dispersion in Gels/Emulsions with Granulated Carbomer

Evonik Goldschmidt GmbH has introduced a granulated carbomer to improve dispersion in cosmetic or pharmaceutical emulsions and gels.

Comparatively Speaking: Carbomer vs. Alkyl Carbomer

Tony O’Lenick looks to Sergio R.S. Costa, of Chemflex Quimica, to explain the difference between carbomer, a series of polymers of acrylic acid, and alkyl carbomer, copolylmerized acrylic acid and alkyl acrylate.

Thickening Challenging Surfactant Systems

Noveon Consumer Specialties has introduced a hydrophobically modified, alkali-swellable emulsion polymer for surfactant systems that are difficult to thicken.

Liquid Polymer Stabilizer/Conditioner for Hair and Skin

Cognis has launched a liquid polymer dispersion that functions as both a stabilizer and a conditioner and imparts sensory properties in hair and skin care applications.

Formulating with Surfactant Silicones

The authors describe how the use of amphiphilic silicones or surfactant silicones has allowed formulators to efficiently incorporate silicone polymers into personal care products. These materials act by lowering the surface tension in the oil phase of a formulation, allowing for easier spreading on skin and hair.
