Recent in Formulating Aids (page 4 of 9)

Eco-friendly, Nonflammable Liquified Gas Propellant

In response to current and possible future restrictions on hydrofluorocarbon (HFC), Honeywell has introduced a propellant that performs like an HFC but exhibits favorable environmental properties.

Polymer Emulsion for Hardness, Gloss and Adhesion in Water-based Nail Polishes

At the 58th Sepawa Congress in Fulda, Germany, Interpolymer introduced a polymer designed for formulation of water-based nail polishes.

Fine Oat Powder for Oil Absorption and Thickening

Oat Cosmetics has introduced a fine oat powder for use in natural cosmetic products. Superfine Oat Flour (INCI: Avena Sativa Kernel Flour) has shown oil absorption, thickening, gelling and texturizing benefits.

Formula Troubleshooting—Microemulsion Systems

Microemulsions have long assisted the pharmaceutical industry in delivering efficacious levels of an active ingredient to the skin by enhancing the active’s bioavailability, versus traditional solutions and dispersions.

PEG-free Solubilizer for Lipophilic Substances

Symrise has introduced a PEG-free solubilizer for lipophillic substances such as perfume, essential oils, actives and vitamins in pure aqueous and aqueous alcoholic product formulations.

Naturally-derived O/W Emulsifier for Skin Care

Seppic has introduced a vegetable-derived, sustainable o/w emulsifier with a light skin feel.

Opacifier for Creamy Cleansing Applications

Dow Personal Care, a business unit of The Dow Chemical Company has launched an opacifier designed to create creamy, conditioning body washes, shampoos and liquid hand soaps.

Formula Anatomy Deciphered—Chelating Agents

The mechanism for chelation, described as a chelate complex, is based on multiple bonding (polydentate ligand) around a single central atom.

Mild Corn-derived Thickener for Surfactant Irritancy Reduction

The Lubrizol Corp.’s Noveon Consumer Specialties has created a naturally derived, mild, nonionic thickener that is said to reduce surfactant irritancy while promoting rich lather.

Simple Solutions

this issue of Cosmetics & Toiletries magazine features articles that suggest how the right tweaks to some fundamental variables can improve formulations. O’Lenick and Lott, for instance, discuss how solvents can impact SPF values and describe a new ester to improve sunscreen efficacy

Microchannel Processing: A Novel Approach to Making Emulsions

In the present article, microchannel emulsification is explored as a process method that precisely adds a dispersed phase into a continuous phase through an engineered dispersion plate. This approach is shown to produce emulsions with smaller droplets having tighter size distributions than conventional means, which leads to stable products with the limited need, if any, for surfactants.

Naturally Derived Suspending Agents

J. Rettenmaier & Söhne GmbH has launched a range of water- dispersible organic hydrocolloids derived from wood fibers for application as suspending agents. Distributed by Gattefossé, the products are designed to improve the heat stability of gels and emulsions.
