Cosmetics

This article presents trends in the frequency of cosmetics as causal factors of allergic contact dermatitis during a 26-year period in 14 911 patients patch-tested between 1990 and 2014 and discusses the cosmetic allergens identified during the last six years (2010–2015) in 603 patients out of 3105 tested The data were retrieved from and evaluated with a patient database developed in-house

Contact lenses – The Organic Solution

May 23 2012A big improvement in the industry came in the 1970s when Wichterle 1 introduced the soft hydrogel polymacon or polyHEMA (poly-2-hydroxyethyl methacrylate) HEMA is synthesised from methacrylic acid and ethylene or propylene oxide and then polymerised to give polyHEMA

Relationship between water structure and properties of

We previously reported that the platelet compatibility of methyl methacrylate (MMA)–2-hydroxyethyl methacrylate (HEMA) diblock copolymers is related to the characteristic water structure in the copolymer as the copolymer has an excess amount of nonfreezing water when compared with that estimated from the amounts of water in HEMA and MMA homopolymers
