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.

Alternative Ingredients for Sustainable Shampoo Development

In this article, several ingredients are reviewed for the development of sustainable shampoo formulations. Some are plant-based alternatives to existing, petrochemically sourced ingredients. Others are mild, sulfate-free and/or ethoxylate-free alternatives; thickening solutions for naturally derived polymers; and efficacy boosters that reduce the use of non-renewable actives with equal benefit for the consumer.

Oral Care to Reach $6 Billion by 2017

While health still primarily drives oral care purchases, consumers also continue to seek oral care products that offer multiple benefits.

Surfactants and Cleansing Products

Today, cleansing products are available in solid bar, liquid and gel forms and can be based on alkaline salts and synthetic and natural surfactants. When substituted for alkaline salts, synthetic and natural surfactants improve the foam structure and mildness of formulas.

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.

Sodium Laurylglucosides Hydroxypropyl Sulfonate For Sulfate Free Formulations

Sodium Laurylglucosides Hydroxypropyl Sulfonate for Sulfate-free Formulations

The use of sulfonated alkyl polyglucosides (SAPG) to replace lauryl sulfates and lauryl ether sulfates in sulfate-free formulations has previously been discussed. These primary surfactants were created with environmental and human safety in mind. The current paper describes more recent work with this material, specifically focusing on the lauryl version of SAPG.

Compass—Connecting the Dots

Whether your bubbles foam or lather, your hair takes a wild turn, or your wellness weighs on the health of microbes, Cosmetics & Toiletries aims to connect the dots.

PEG-2 Caprylylamine: A New Adjuvant Surfactant to Boost Lather Rate

PEG-2 caprylylamine, when used as an adjuvant surfactant formulated in a basic cleanser, can significantly increase lathering rate, as sensory evaluations, dynamic and static surface tension measurements, and the Ross-Miles method show here. Mechanisms of action for this new field of research also are discussed.

Water-soluble Phosphate Polymers in Bar Soap for Controlled Release of Antimicrobial Silver

This paper presents data on the antimicrobial performance of a silver ion-releasing phosphate polymer incorporated into a bar soap product. Two studies test the speed, efficacy and longevity of the antimicrobial effect, highlighting the potential of these materials for the controlled, sustained release of bioactive metal ions in cosmetic products.

Improving Deposition From High-water Formulas Using Amphiphilic Polymers

Effective high-water skin care systems may play an important role in addressing emerging market consumer needs. The present study considers the challenges of such systems, particularly regarding the deposition of ingredients across water solubilities, and proposes an amphiphilic cationic polymer as one possible solution.

Structured Surfactant Systems for Improved Lasting Deposition of Perfume on Skin and Hair

To maximize perfume delivery from structured cleansing formulations, the fragrance must be introduced before structuring the formulation into multilamellar vesicles. Structured formulations fragranced in such a way are shown here to improve perfume deposition and duration versus micellar systems, with no negative impact on perfume burst during use.

Bar Soap Containing Water-soluble Phosphate Polymers for Controlled Release of Antimicrobial Silver and Other Bioactive Metal Ions

This paper presents data on the antimicrobial performance of a silver ion-releasing phosphate polymer incorporated into a bar soap product. Two studies test the speed, efficacy and longevity of the antimicrobial effect, highlighting the potential of these materials for the controlled, sustained release of bioactive metal ions in cosmetic products.

Formula Anatomy Deciphered—Feminine Hygiene Products

When personal care products are formulated to maintain the hygiene of the external genital area, specifically the female genitalia, they must have distinctive characteristics. These products must address the female genitalia’s complex anatomy, physiological elements and role in body metabolism and reproductive functions.

Comparatively Speaking: Shampoo vs. Body Wash Formulation

Tony O’Lenick asks David Zhang, PhD, to explain the difference between two major classes of cleansing products: shampoo and body wash.
