Have this to say about titanium dioxide
Is accepted as a safe Sun Barrier all around the world. This is because it is inorganic and has a record of having no adverse reactions to it. This makes it ideal for products used on a daily basis.
It can be used in Sun Screens, Moisturisers, Powdered Make-up, Lip and Baby products and virtually any Skin Treatment product.
Adding 5% Microfine Titanium Dioxide to a product gives it a Sun Protection Factor (SPF) of approximately 10 and protects against 90% UVA/UVB and UVC radiation. Adding 10% gives it a SPF of 15-20.
Add during the heating of the Vegetable Oil in the Fat Stage of making your product. You need less of this than Tiosol, so it is very cost effective.
Visit the Aromantic Skin Care Library on our website for more information about Microfine Titanium Dioxide. There is a link to the library on our home page.

have this to say
There may be a side to your sunscreen you don’t know. Ever stopped to read the ingredients of your sunscreen bottle? Even sunscreens that use (or rather “misuse”) the term “natural” may include ingredients like titanium, parabens and petroleum based derivatives. Conventional sunscreens have ingredients which have dubious long term health effects. “The vast majority of today's sunscreens are nothing more than poisonous concoctions loaded with suspect carcinogens” (Mercola.com).
Octyl methoxycinnamate (OMC), for example, which is present in around 90 per cent of sunscreen brands, has been found to kill mouse cells even at low doses in a study by Norwegian scientists. Titanium Dioxide is also often used in conventional sunscreens. Titanium Dioxide is a photo-activator that can react with other sunscreen chemicals and promote their free radical production or their cancer forming abilities. Recent studies have shown that Titanium damages the DNA of the cell and it has been listed as a potential carcinogen.
Sunshine has important health benefits, but protecting ourselves, and in particular our children, from excessive the sun can tricky. The answer is to avoid harsh sun and use sunscreens that are effective and non-toxic. We stock the UV Naturals and Soleo brands.
