Shampoo Boosts Drug-resistant Bacteria

Scientists at Birmingham and Warwick universities have warned that fabric softeners, disinfectants, shampoos and other household products are spreading drug-resistant bacteria around Britain. Once these products are released into sewers and rivers they instigate the proliferation of drug-resistant microbes, increasing the likelihood that certain medicines will not be able to combat dangerous diseases.

The research suggests that the problem of drug resistance is not simply due to antibiotics being over-prescribed or poor hygiene standards in hospitals, although the emergence of deadly superbugs such as MRSA are not linked to the use of disinfectants.

Europe Bans Two Chemicals From Cosmetics

The European Union has prohibited two chemicals from being used in cosmetic products, in a recent amendment to the European Cosmetics Directive. From November 5, 2009 companies are barred from using diethylene glycol (DEG) or phytonadione. This action has been taken following the discovery of high levels of DEG in some toothpaste products from other markets. Although a representative of the industry trade association, the Cosmetics, Toiletries and Perfumery Association (CTPA) suggested that reputable brands do not use DEG, trace levels are often present as an impurity in widely used ingredients such as glycerol.

Petrochemical Compounds: An Introduction

A petrochemical compound is an organic (based on carbon) compound derived from crude oil (petroleum) or natural gas, which were formed millions of years ago in the earth’s crust from decayed plants and animals.

These two primary classes of petrochemical are olefins (e.g. ethylene, butylene and propylene) and aromatics (e.g. benzene, toluene and xylenes) produced by chemical cracking (breaking large hydrocarbon molecules into simpler molecules, aided by a catalyst and high temperatures) and catalytic reforming (used to convert low-octane naphthas into high-octane gasoline blending components and often benzene, toluene and xylene aromatics for Read more

Alpha Hydroxy Acids: Miracle Workers or Skin Wreckers?

Alpha-hydroxy acids (AHAs) are lauded by the cosmetic industry and even dermatologists for their alleged anti-ageing properties. AHAs are a group of acids derived from a variety of sources, including fruit and milk sugars. There are a range of AHAs used in cosmetic products, including: glycolic acid, lactic acid, malic acid, tartaric acid, citric acid, ammonium glycolate, ammonium alpha-hydroxyethanoate and alpha-hydroxyethanoic acid. They are used in cosmetic products as exfoliants to remove the outer layer of skin, supposedly revealing fresher, younger, smoother looking skin underneath, and as moisturisers and emollients. Dermatologists and cosmetic surgeons use AHAs in much higher concentrations than cosmetic products Read more
