Make your own suncream!

I have done this for about 7 years now, it works really well and you get an excellent tan. You need a moisturing cream you can tolerate, I use Aqueous Cream BP, it's cheap and basic.
Into that mix titanium dioxide powder (titanium appears to be one of the least troublesome chems for folks who react badly to chems) - the ratio for Factor 20 suncream would be 1 tablespoon of titanium powder to 10 tablespoons of moisturing cream. Mix well & put in fridge ready for use.
Microfine titanium has very fine particles which create little mini-clouds as you scoop it out of the bag, so you might want to wear a mask while measuring it out.
Here's where I get mine http://www.aromantic.co.uk/buy-microfine-titanium-dioxide-uk.htm - they're apparently out of stock at the moment but have a google around, I'm sure you'll find some more. :)
Useful to know if you run out of suncream
uck for some reason that link is not working - more gremlins...it will only work if I add it separately (above). You can also google "In vitro sun protection factor determination of herbal oils used in cosmetics" & the paper should come up..
Enjoy the summer! :-D
I like the light-hearted but informative nature of the sales blurb from the company too
www.purenuffstuff.co.uk/sun-protection/… like a good set up, I've just ordered a items from them.
