Profile of 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.

KahlWax Introduces Rice Bran Ester Wax for Oil Gels

At in-cosmetics Asia, KahlWax will present a versatile rice-bran wax that can be used to lend consistency to oil gels such as lipsticks, hair wax and mascara.

Effect of Perfumes on the Viscosity of Surfactant Systems

It is well-known that perfumes can affect the viscosity of bubble bath or shampoo formulations. Usually they have a thinning effect, but they can also cause a viscosity increase. The effect and its magnitude will vary with perfume type and also with the product formulation. Small changes in the latter can cause large changes in a perfume's effect on the viscosity.

Formulating for Electrolyte Resistance in Conjunction with Sensory Appeal

Skin care formulations often are enriched with high levels of electrolytic ingredients for various skin benefits. However, these have a negative impact on the viscosity, texture and stability of a system. Described in this article is a multifunctional polymer that is designed to provide excellent electrolyte resistance along with a pleasant sensory profile, as will be shown.

Seppic Launches Rheology Modifier for Clear Cleansing

Seppic has expanded into the personal hygiene market with the launch of its new rheological modifier Eliclear 4U (INCI: Acrylates Copolymer).

Successfully Formulating at the Skin’s Natural Surface pH

Formulating high-performance skin care systems at low pH levels (4.0 to 5.5) can be beneficial for consumers and formulators in many ways, according to Florence Pecquerie, applications scientist and formulator for Lubrizol. Here, she reviews the current knowledge on skin surface pH, discusses the importance of pH on the efficacy of organic acid preservatives in formulation and introduces a new crosslinked acrylic acid homopolymer.

Croda Adds Rheology Modifier to High Oil/Silicone Creams

Croda has added a rheology modifier to its ViscOptima range that can emulsify and stabilize high levels of oils and silicones in a formulation.

Evonik Launches Color Cosmetic Emulsifier and Viscosity Enhancer for Cleansers

Evonik has introduced two new raw materials: a polyacrylic acid copolymer rheology modifier for mild cleansing and a silicone-based emulsifier for w/o color formulations.

Profile of 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.

Next-generation Carbopol® Polymer Proves Highly Efficient at Lower pH Levels

Consumer demand for products that provide anti-aging and healthy-skin benefits is driving the creation of many new cosmetics. However, many of the active ingredients that are beneficial to the face and neck are most effective at lower pH ranges. In this Q&A, Lubrizol’s Bryan Moran, Sr. R&D Scientist, talks about Carbopol® Ultrez 30 polymer (INCI: Carbomer), a new rheology modifier, and how it can help formulators achieve preferred viscosity, suspension and stability in gels or emulsions containing challenging additives such as alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs).

Lubrizol Debuts Carbomer with Electrolyte Tolerance, Thickening and Broad pH

Lubrizol has added a new rheology modifier to its Carbopol range that offers electrolyte tolerance, high thickening performance in a broad pH range and rich, distinct sensory attributes in challenging skin care formulations.

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.
