Addressing Tooth Sensitivity and Dental Erosion

While the introduction of fluoride remarkably increased the life expectancy of natural teeth, two oral care problems have since emerged: tooth sensitivity and dental erosion. This article describes approaches to these problems and discusses the challenge of simultaneously maintaining fluoride efficacy in multi-benefit toothpaste formulations.

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.

Naturally Derived Low Dioxane Solutions for Cleansing Products

The demand for personal care products made with natural, renewable materials shows no sign of abating. Lubrizol is responding by launching two new products: a naturally derived thickener, Glucamate™ CCO thickener, a product that builds viscosity without ethoxylation while offering broad ingredient compatibility; and a new high-solids surfactant, Sulfochem™ ES-70DXS surfactant, that pushes 1,4 dioxane levels closer to single digits and is extremely easy to handle. What’s more, the cleansing products they enable still deliver the sensory and safety properties that consumers expect.

Viscosity, Dispersion and More in Mascara

Cosmetic formulators are constantly challenged to develop products for daily use, and mascaras in particular are one of the most researched (and scrutinized) products a woman can purchase. Scientists must go to great lengths to ensure this miracle product delivers on the eyelash benefits it advertises.

Polyacrylate-33 for Thickening and Suspending in Low Surfactant Cleansers

Described herein is a hydrophobically-modified acrylic copolymer, polyacrylate-33, which is designed for low-to-medium surfactant-containing cleansers. The ingredient is shown to display high thickening efficiency and good suspension properties and shear-thinning rheology in sulfate-based and sulfate-free chassis. Further, it enables transparent formulations in the presence of salt with improved foaming and sensorial properties.

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.

Nonaqueous Emulsions: History and Current Specialized Applications

Since the early 1980s, nonaqueous emulsions have attracted technical interest as potential vehicles and delivery systems for personal care products. This is due to the development of a broad range of silicone-based emulsifiers, silicone polymers and other polymeric emulsifiers that have enabled their use. This article will briefly review their history and evolution into current-day specialized applications.

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.

Using Esters to Deliver Multifunctionality in Color Cosmetics

Color cosmetic claims are becoming increasingly sophisticated and interconnected to trends seen in the skin care category. The Liquiwax® range of cosmetic esters combines the emolliency of traditional esters with skin conditioning functionality to address the consumer need for skin care effects in color cosmetics.

Nonaqueous Emulsions: History and Current Specialized Applications

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.

Croda Introduces Sensorial Ingredients for Skin, Hair and Sun

At in-cosmetics 2013, Croda will be introducing a host of sensorial ingredients across the skin, sun and hair care categories in addition to debuting new formulations for the Asian and Latin American markets.
