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
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
Among the many things I try to cram into my schedule is a newsletter for people with sensitive skin. I am not very successful at doing this I am afraid, and I don’t get the newsletters out very frequently. But despite this I get a steady stream of people talking to me about their issues with reactions to cosmetics. In particular, to preservatives. And particularly in particular to methylisothiazolinone. Continue reading
There are an interesting couple of points in the comments thread on my blog post asking for MI not to become a scare story, from Suzanne. She has drawn my attention to a paper from 2012 that details developmental problems in tadpoles exposed to MI. She concludes from this that MI is potentially unsafe for humans as well and asks what the liability is for companies that continue to use it now that this risk has been identified. Continue reading
Someone has asked about a serum they like.
I have a very very expensive formulation of a serum here. Would you please be so kind to evaluate it? My questions are especially concerning preservatives.. and also: does skin benefit from so many different ingredients and antioxidants…? I think I think that simple is best. The formulation might be of interest to you, as it seems at the forefront.
Water, tetrahexyldecyl ascorbate, glycerin, punica granatum (pomegranate) extract, squalane, tocopheryl acetate, camellia sinensis (white tea) leaf extract, vernonia (ambiaty) apendiculata leaf extract, morinda citrifolia exrtact, pichia/reservatrol ferment extract, laminaria digitata extract, padina pavonica thallus extract, hydrolyzed algin, palmitoyl oglipeptide, phanthenol, niacinamide, ubiquinone, yeast amino acids, 7-dehydrocholesterol, simmondsia chinensis (jojoba) seed oil, helianthus annuus (sunflower) seed oil, triticum vulgare (wheat) germ extract, helianthus annuus seed extract, equisetum arvense extract, commiphora myrrah extract, retinyl palmitate, allantoin, PEG 10 rapeseed sterel, tribehenin, ceramide 2, C12-15 alkyl benzoate, ammonium acryloyldimethyltaurate/beheneth-25, sucrose laurate, polyacrylate crosspolymer-6, polyquaternium-55, zea mays (corn) oil, ethylhexylglycerin, phenoxyethanol, tricalcium phosphate.
There is a news story that L’Oréal have issued a product recall for their Ideal Moisture Dry and Sensitive Day Cream in Canada. The reason is that the level of MI in it is higher than Health Canada’s regulations allow. This is quite a rare event – big cosmetic companies are usually pretty good at following regulations. Unfortunately Google has not revealed the details of just how much over they were. But the product has been on the market for three years so there is a good chance that they have simply failed to keep up with the regulations and that the product was legal when formulated and launched. They have shifted just under 60,000 units. Continue reading
I have just had someone get in touch to tell me that Ecover Wipes have just changed their formulation to include methylisothiazolinone (MI) as the preservative. I haven’t been able to confirm this myself so I will have to treat it as hearsay for now. If you know the facts please let me know. But it does raise the question as to why any company would do such a thing? MI has been in the news for provoking allergies and the permitted level has been tightened recently. It has even been banned from leave on products – though it is still allowed in rinse off products such as wipes. Continue reading
Regular readers will know that any aqueous cosmetic product needs a preservative to stop it going mouldy. Preservatives tend to get a bad press, and given that most of them are inevitably toxic they are probably going to carry on getting it. Preservatives get a lot of attention not only from journalists and the nervous, but also from regulators. The EU cosmetic regulations only permit certain preservatives and only allow them at prescribed levels. This means that the job of supplying preservatives is a difficult one. Not only are you always dreading a bad news story, you can also wake up to find that the regulations have changed and you can no longer sell your product. Continue reading
It is a sad fact of life that not many of the fancy sounding ingredients that cosmetic companies add to their formulations add much to the benefits those products have for your skin. A good moisturiser is a pretty handy tool for dealing with dry skin, but how much of the good it does you comes from the things that the pack talks about is usually pretty minimal. But there are a few things that do have some real effects, and one of them is vitamin C. Continue reading
