COTZ SPF 58 HAS BEEN DISCONTINUED.
Contains Only Titanium & Zinc
COTZ™ is mineral based, utilizing ultra-micronized titanium dioxide and zinc oxide as its approved active sunscreen ingredients. COTZ is free of dyes, fragrance and is "chemical sunscreen free" (some individuals experience skin sensitivity due to chemical sunscreen filters). COTZ is excellent for pediatric use as well as for those with sensitive skin. It offers significant water resistant properties making it ideal for all outdoor activities. COTZ SPF58 sunscreen is elegant and highly protective for daily use, leaving the skin soft, smooth and UVA/UVB protected. COTZ is oil, PABA and fragrance free.
Physical Blockers in Total Block
Two forms of titanium dioxide were selected for Total Block. First is an opaque, cosmetic form that reflects and scatters most wavelengths of UVB, plus some UVA. Second is sub-micronized "transparent" titanium dioxide. This form of titanium dioxide allows for a much higher percentage of protection while retaining cosmetic elegance, and achieving an increase in UVB protection. Together, these two titanium dioxides (differing only in particle size) obtain excellent UVB protection (High SPF) plus moderate UVA protection.
Zinc Oxide has been used topically for centuries as a skin protectant and wound healing adjuvant. It is a recognized mild antimicrobial agent. Zinc oxide absorbs, rather than scatters most UVA (titanium dioxide primarily scatters). Therefore, ultrafine zinc oxide "closes the window" in the UVA range, left open by titanium dioxide.
More than 50 years ago, zinc oxide was indicated as a potential block for ultraviolet light (UV-A). It also reflects infrared from the skin, as does titanium dioxide. However, its ability to protect in the long UVA range is much higher than titanium dioxide. Zinc oxide absorbs, rather than scatters, most UVA while titanium dioxide primarily scatters these wavelengths. Therefore, ultra-fine zinc oxide "closes the window" in the UVA range, left open by titanium dioxide. Zinc oxide works to both complement titanium dioxide's protection and extend photoprotection to the skin where titanium dioxide is insufficient. The optimal particle size range for ultraviolet-blocking zinc oxide (without blocking visible wavelengths) is approximately 80 to 150 nanometers (1,000 nanometers = 1 micron).
Supplementing the opaque and "transparent" titanium dioxides in Total Block is "transparent" sub-micron zinc oxide (Z-Cote ™). Its protective abilities cover UVB and a majority of UVA radiation.
We commonly see iron oxide in cosmetics to give the cover-up color desired. Cosmetic iron oxides are man-made to very high purity, color, and particle size. Research has demonstrated that these cosmetic pigments not only add color to the lotion, but also contribute significant protection of the skin. Equally important, these metal oxides act as a "heat-sink" to lower the heating action of infrared rays on the skin. Iron oxide pigments are micronized powders that, by controlling the temperature and rate of drying during manufacture, are available in a number of shades and tones of red, yellow, black and brown (and blends of these basic colors). These cosmetic pigments (if incorporated at adequate concentration), when properly dispersed in well-designed vehicles not only add color to the lotion (or cream, powder, etc.), but contribute significant protection of the skin from all "light" forms (UVC, UVB, UVA, Visible).
Indirect Physical Blockers in Total Block
To boost the effectiveness of the various "oxide" particles in Total Block, special ultra-flat particles are incorporated. They themselves are very small, pleasant feeling particles but much larger than direct physical blockers. These overlapping particles increase protection on the skin.
