Software Tool to Keep Track of Rheological Data

ATC RheoSystems introduced RheoExplorer V6 Software that promises to deliver easy use, real-time printing and plotting, and advanced data-analysis capabilities.

Seeking Homogeneity in UV Filter Distribution

The uniform distribution of UV filters on the skin and in the skin should be a goal for sunscreen formulators because it improves sun protection and increases the SPF. If it also improves the condition of the skin, consumers receive two benefits for the price of one. The good news? It can be done.

Formulators Forum--Optimizing Your Emulsion to Meet Marketing Requirements

Cosmetic formulators are given product briefs from our marketing friends and then we go off to the bench to create our masterpiece. After we submit our idea of what we think the brief really meant, someone from marketing gets back to us and tells us that it doesn’t feel right.

Conductive Organic Polymers, Methods for Conductive Patterns for License

A group of methods to pattern conductive organic polymer layers on a support is offered.

Powder Batching, Weighing from IM

Ingredient Masters (IM) introduced customizable batching and weighing systems for flaked or powdered ingredients.

Gold Nanoparticles Reduce Toxic Waste in Cosmetic, Perfume Production

Perfume, paint and cosmetics can be manufactured without producing as much toxic waste, according to recent report.

Formulating for Efficacy

Via the introduction of the Relative Polarity Index, the authors show that the choice of emollients in cosmetic formulations determines the total amount of skin penetration of active ingredients whereas the choice of the emulsifier determines its distribution within the skin.

Personal Care Wipes: Manufacturing Practices & Microbiological Control

In order to control microbial contamination in personal care wet wipes, one must understand the substrate raw materials, the requirements of the manufacturing environment, the complexity of the product system and the specialized equipment employed in the processing and packaging operations.

Linking Sensory and Rheology Characteristics

The authors introduce a method to use rheological properties (such as dynamic viscosity and yield stress) to describe and predict skin sensory attributes (such as cohesiveness) of cosmetic products. This is a first step in learning to use emulsion structure to predict sensory attributes.

Evaluating a “New” Emulsifier

Cosmetic chemists are constantly being bombarded by “new” raw materials from suppliers. We welcome this “bombardment” as it gives us the opportunity to be more creative in our formulation efforts. I think it is worthwhile to step back and look at how a formulator should evaluate a new material before deciding whether or not to use it. Let’s focus our attention on emulsifiers (one of my favorite topics).

Enabling Advanced Emulsions in Microchannel Architecture

An innovative emulsification technology is demonstrated, which can be applied to surfactant-free emulsions and has the propensity for stimuli-responsive behavior. The technology can be used to allow previously difficult product formulations with shear-sensitive materials and controlled, droplet size distribution.

Transition Metal-Induced Oxidation: Implications for Skin Care Products

Transition metals in the skin affect the skin's pro-oxidation response to external stresses, well-known antioxidants and common chelating agents. The chemistry of transition metal-induced oxidation has implications for the development of skin care product
