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
I don’t think that animal testing works the way some people commentating on the internet appear to think it works. This was brought home to me when I was asked a question about a new preservative material called silver citrate. It is one that might appeal to the lovers of natural because both silver and citrate sound safe and natural. We all know what silver is and so assume it is safe. Citric acid sounds like it comes from oranges so that sounds pretty safe too. But the person who was interested in it had read the material safety data sheet that came with it, and concluded that it had been tested on animals. For them this was a no no. Continue reading
I have just seen a post on Facebook where someone is wondering about how much beer they need to put in a beer shampoo. They aren’t very sure – in fact they are considering anything between 5 and 50%. That’s a lot of beer! The only thing they are sure of is that they need to open the beer the day before to let it go flat. Continue reading
I have just got off the phone from discussing a citrus fruit extract I have commissioned. I have been disparaging in the past about what are called tip ins – but there are times when you want a particular extract and it is rather splendid that companies exist that have the expertise and capabilities to produce, within reason, any extract that you want.

Some things I write about seem quite important to me but somehow don’t really resonate with the people who read my blog. For example I wrote a post on palm oil which explained how the palm oil business works. Nobody read it. But I still think it matters so here we go again. Basically palm is grown on plantations and then processed to produce palm oil. This all goes into a big system from where it is moved around to produce a bewildering number of products.

A question about an ingredient from Sara.
Hi, just wondering if you could give some information on the preservative Polyaminopropyl Biguanide? Apparently it was banned by the EU in January 2015 however appears to be still used in many beauty products including up to very recently Liz Earle’s cleanse and polish. Many thanks.
I am not a big fan of Facebook. I find the interface a bit busy and confusing, and I haven’t really worked out who can actually see stuff when I post it. But it is a big platform so I feel obliged to got on it every now and again. I was on it recently and a side bar suggested I should join a group called “Get Methylisothiazolinone Removed From Products!”. It sounded interesting so I clicked on it and thought no more about it.

A Twitter friend asks what an astringent is. And the answer is basically quite straight forward on one level. It is something that stings the skin and stimulates it to react. The easiest way to think about it is to consider the material that is most often used as an astringent, or at least most often used in conjunction with the word astringent, which is witchhazel. If you know what witchhazel does, then that is an astringent. The main experience I have had of witchhazel was having it applied to wounds and bruises as a kid. I was told then that it would clear away the germs and stimulate the skin so that the wounds or bruising would heal more quickly. Continue reading
Preservatives in cosmetic products are a problem and will remain so until the way they are made and used changes significantly. I imagine someone somewhere is working on a project to create cosmetics in a small machine which you can programme with your favourite recipes. That would enable people to choose their own preservative option or to not use them at all and just make their personal care products fresh as needed. But until that technology becomes widespread preservatives are a necessity, and some people will have allergic reactions to them. Even the ones with a low propensity to cause allergic reactions, like the parabens and methylisothiazolinone, still cause plenty of people issues.? Continue reading
There’s a new paper out with some numbers from dermatology clinics about reactions to methylisothiazolinone (MI). Dermatologists regularly patch test people to discover what they are allergic to. This involves applying a set of common materials that tend to provoke allergic reactions to the skin, and seeing which ones the individual reacts to. Continue reading
