There isn’t anything that really beats old fashioned soap and water for keeping your skin clean and clear of bacteria. This is comforting information. We’ve all got soap to hand so we can at least keep ourselves germ free at home. Soap has a double effect. Its cleaning action removes the invisible droplets that might contain infective material. Its high pH and disruptive effect on membranes put stress on microbes – killing or at least weakening them. This isn’t instantaneous: the medical profession recommend a 20 second contact time. Hands need to be kept clean to stop them transferring contamination to other parts of your body. So make sure that the whole hand gets the treatment. Pay attention the backs of the hands, the areas between your fingers and most importantly of all the space between your finger nails and the tips of your fingers.
I think this is a universal truth, but it is certainly true in labs. The most stressful role is middle management. I enjoyed my time as a bench chemist doing the actual work. I enjoy supervising projects at a higher level. But most of my bad memories of my career are when I was in between – managing a team but reporting to senior management. Continue reading
There is an article I have seen posted on Facebook a couple of times that highlights the health risks of synthetic fragrance ingredients. I won’t link to it, but if I am seeing it there is a good chance you will have seen it too. The thesis it proposes is that synthetic chemicals in fragrances are toxic and might be dangerous to people who inhale them in public places, even if they aren’t actually wearing the fragrance themselves.

Fashions come and go in the cosmetics and personal care world, and everyone is keen to be on the latest trend as soon as possible. The latest buzzy thing seems to be Cannabidiol or CBD. This has an interesting background, being a derivative of hemp which is also the source of cannabis – which has been a popular if illegal recreational pharmaceutical since the sixties. So CBD comes with ready made notoriety. But it is currently being sold not as a gateway into a counter culture, or even as an aid to relaxation, but as a substance with health benefits.

What is the difference between a drug and a Cosmetic?
The simple answer is it depends on the claims you make for it. So if you sell a shampoo to treat dandruff, it is a cosmetic. If you say it cures psoriasis then that makes it a medicine. The more complicated answer is that if you present a product in such a way as it seems to be making medical claims then there is a good chance that the regulators will take notice and take action. This rule is pretty much a universal one. There are differences from market to market on just what will trigger off an enforcement, but the principle is always the same. Continue reading
We now live in a world where information is freely available in quantities much greater than we can possibly need. But information is not knowledge. Knowing facts isn’t much use without the knowledge of how to use them. A story I came across made this clear to me. A gentleman had bought a deodorant specifically because it had a big ‘alcohol free’ splash on the pack, and he reacts to alcohol. But in fact he still had very bad reaction to the product. When he looked at the ingredient list he noticed it contained benzyl alcohol. So, he concluded, the product was not alcohol free at all! Continue reading
I am not religious, but I was struck once by something a Catholic priest said on the radio. He was talking about a seminar they had just had on morality. “It’s easy to agree on principles. The arguments start when you get into the details.” Well I don’t know about morals, but that is certainly true when it comes to cosmetic claims. The principle is pretty simple. You are only allowed to sell your product on the basis of legal, decent and truthful declarations. No argument there. The problems start when you actually start making those claims. Continue reading
There is no doubt about it. The biggest thing that makes your skin look old is sunlight. There is plenty of academic backup for this suggestion, but most of us can prove it simply by looking at ourselves. Areas of skin that are routinely exposed to light always look older than parts that don’t. In my case I have the habit of rolling my sleeves up in summer and the skin just below the join is rougher, darker and more hairy than above. Continue reading
Grey hair is something we can all look forward to. That the genes have something to do with it is pretty clear. Some people go grey in their twenties – a few put it off until their fifties or even later. And it is very rare that someone goes grey and then turns back again. So it is a pretty safe bet that this is not strongly an environmental thing. Continue reading
This was a question posed to me by a journalist on the Daily Telegraph. The answer is of course no, but I’ll get onto that later. First this is quite an interesting example of how stories like this originate. Here is the full text of the e-mail I was sent. Continue reading
