Researchers Suggest New Way to Look at Manufacturing Emulsions
Dec 14, 2011
Researchers at Harvard's School of Engineering and Applied Sciences (SEAS) have discovered that stabilized emulsions may take months to years to reach equilibrium. This research has important implications for the manufacturing processes used in pharmaceuticals, cosmetics and foods, among other chemical industries.
Comparatively Speaking: Patent vs. Trade Secret
Nov 2, 2011 | Anthony J. O'Lenick Jr., Siltech LLC
In this "Comparatively Speaking," Tony O'Lenick explains the difference between patents and trade secrets, both of which cosmetic chemists will encounter during their careers. This information will assist in determining whether a technology should be patented or maintained as a trade secret.
Properties of O/W Emulsions with Anisotropic Lamellar Phases
Oct 28, 2011 | Gerd Dahms, ICI Specialty Chemicals Group, Atlas Chemie
In cosmetic and pharmaceutical creams and lotions, fatty alcohols are well-known as viscosity modifiers. In addition, Schulmann and Cockbain found that the stability of oil-in-water emulsions was greatly increased by addition of cetyl alcohol.
The Harvest of Marine-derived Cosmetic Ingredients: A Case Study of Pseudopterogorgia elisabethae
Aug 1, 2011 | Nava Dayan, PhD, and Albert Babik, Lipo Chemicals Inc.; Tim Higgs; and Howard R. Lasker, PhD, University at Buffalo
This paper reviews the knowledge and nature of the harvest practices for the octocoral Pseudopterogorgia elisabethae. P. elisabethae extract has been used for nearly two decades in cosmetics and preparations for skin benefits, and a review of the harvest provides product developers with an interesting case study of the harvest of a marine resource.
Formula Troubleshooting—From Lab Bench to Production
Aug 1, 2011 | Peter Tsolis and L. Grotzinger
Led by column editor Peter Tsolis of The Estée Lauder Companies, this recently added column in the Cosmetics & Toiletries magazine lineup covers some of the more common formulation challenges and suggests solutions for novice formulators as well as seasoned experts.
Properties of Emulsions: Structure and Skin Penetration
Jul 19, 2011 | Th. Förster, B. Jackwerth, W. Pittermann, W. von Rybinski and M. Schmitt, Henkel KGaA
This work studied the influence of emulsion type and structure on the penetration of vitamins as cosmetic active ingredients. An emulsion of the w/o type and two different o/w emulsions were compared with an oil solution as a standard. A systematic in vitro study of penetration into the stratum corneum and the living skin was performed with the isolated perfused bovide udder skin model. The results substantiate the influence of emulsion type and stucture on the degree of penetration of water-soluble and oil-soluble vitamins into the skin.
Scale-up Basics for Fomulators and Process Engineers
May 2, 2011 | Bob Bornfriend, Alberto Culver
This article aims to help novice formulators understand issues that arise from the scale-up of their recipes, and to remind experienced formulators of some of the less common pitfalls. It also focuses on the unique demands of process development for global implementation at multiple sites, specifically pertaining to the scale-up tasks for process engineers at multinational companies.
Protection of Retinol in Organosilica Microparticles
May 2, 2011 | Kim S. Finnie, PhD; and Chris Barbé, PhD, Ceramisphere Pty., Ltd.
In this article, retinol encapsulated in organosilica microparticles (12–14% w/w) having an average particle size of 0.3 micron are shown in a 40-day test period to exhibit enhanced stability to oxidation when compared with similar commercial stabilized retinol products.
