Patent Pick: Unsticking Emulsion Sticking Points

What's sticky, unstable and causes skin irritation? Certainly not emulsions based on core corona-type microgels. In a new patent application, Shiseido inventors explain how these materials produce the very opposite effects.

O/W Emulsions Enriched with Vitamin E

Vitamin E has an important protective function for the entire organism. It is believed that the broad biological activities of vitamin E are due to its ability to inhibit peroxidation and stabilize biological membranes.

Emulsion Stabilizer Derived from Orange Pulp

Fiberstar Inc. will launch an emulsion stabilizer derived from orange pulp with a chemical composition that imparts both hydrophilic and lipophilic properties during In-Cosmetics in Paris.

Cellulose Nanocrystal, Lauric Arginate Complexation Key to Pickering Emulsion Stability

Work published in Food Chemistry shows how food-grade Pickering o/w emulsions display good stability thanks to complexation between cellulose nanocrystals and lauric arginate.

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 Inhibit Fragrance Degradation: Rice Bran Sterols in Emulsions

The use of phytosterols is proposed here to retard the deterioration of cosmetic emulsions caused by perfume degradation. For the described tests, phytosterols from crude rice bran oil, a natural and economic choice, were used. A simple and easily controlled technique is described through which the phytosterols provided the desired results.

Uniquely Stable Emulsions Revealed Through Freeze-fracture Transmission Electron Microscopy

Researchers investigated the structures and features of emulsions made with different emulsifiers via freeze-fracture transmission electron microscopy. Potassium cetyl phosphate formed more multi-lamellar spheres than other emulsifiers, and aggregated homo-domains on top of lamellar sheet surfaces and multi-lamellar spheres. These homo-domains are likely to be responsible for the excellent emulsion stability achieved.

The Barrier Redux Emulsion is composed of 14 sustainably-sourced ingredients.

Evolved By Nature Debuts First Skin Care Product, Barrier Redux Emulsion

The serum features Activated Silk 33B, which helps to support the skin barrier cells that produce claudin, a protein that binds skin cells together for a firmer, healthier-looking skin barrier.

The Effects of Showering Too Often, Too Hot and Too Long

This article is about something that anyone with teenage children will recognize: the fact that while you cannot get pre-teens to go into the shower, you cannot get teenagers out of the shower. However, when their showering is too often, too hot and too long, they are steam-stripping their skin.

Clean and Green: A Review of Modern Day Surfactants and Emulsifiers

Many certified organic shampoos and body washes use soaps such as potassium cocoate as their primary cleansing agent, partially due to a lack of suitable, organically approved foaming alternatives. This article reviews the use of modern surfactants and emulsifiers developed based on a green and eco-conscious philosophy.
