Titanium Dioxide- The Linking Filler for Life Sciences Applications
Titanium Dioxide (TiO2) commonly used as pigment across the multiple applications has a strong advantage with benefits pure, earth-derived ingredients can offer. TiO2 is inert – which means it will not react with other ingredients.
This allows it to be used in products consumed orally and also applied to the most sensitive areas of the body, including around the eyes, eyelids and mouth, with a greatly reduced risk of allergic reactions.
In personal care, skin care and color cosmetic applications, TiO2 provides high color context, including higher intensity and brightness, helps absorb oils released from the skin, and provides ultraviolet protection to the skin, making it highly suitable for sun care products.
The rising demand for skin care products due to increasing awareness regarding inclination toward maintenance of an even skin tone, healthy skin rituals, and efforts taken to look beautiful and young is fueling the demand for skincare products.
The Applications Include:
• Liquid and powder-based foundations,
• Eye Shadows,
• Suncare Products,
• Soaps / Shampoos,
• Nail Polishes,
• Body Lotions & Creams.
The use of pigment form TiO2 with other colours gives intensity and brightness to decorative cosmetics, as well as allowing manufacturers to create many different shades to suit all skin types in foundations and lipsticks.
Non-pigment form TiO2 is a key ingredient in sun care products, absorbing and scattering both UVA and UVB rays, which prevents sun burn and premature ageing. This can be harnessed in cosmetics too, giving UV-protection properties to creams, foundations and lipsticks.
Use of ultrafine TiO2 enables the sunscreens to be applied as a clear film that consumers prefer over the antiquated, white opaque lotions. TiO2 helps soak up oils in the skin, while lending it an opacity that reduces any unwanted shine – a key selling point for any matte-based cosmetic.
In Food, Neutraceutical & Pharmaceutical applications, TiO2 needed to be managed with higher purity and brightness. The purity should be in range of 99% and heavy metals should be very well controlled, example: Lead should be less than 10 ppm, arsenic should be less than 3 ppm, etc.
As a pigment, titanium dioxide is a FDA Approved Additive used to enhance the white color of certain foods, such as dairy products and candy, and to add brightness to toothpaste and some medications. It is also used as a flavor enhancer in a variety of non-white foods, including dried vegetables, nuts, seeds, soups, as well beer and wine.
There are regular and surface-treated TiO2 products on the market for various applications. The regular grades of Ti02 offered are available as Rutile & Anatase grades and customised in different particle size and superior soft textures. Surface treated TiO2 offers superior advantages in textures, brightness and dispersibility in different medium.
Surface treated TiO2 coated with different entities like Tri-ethoxy Capryl Silane, Laurel Lysine, Dimethicone etc for different properties. TiO2; through to the performance properties it provides to the end product, it is a raw material that is widely used for various purposes in different sectors such as cosmetics, food and medicine.
Its use is of great importance in many sectors, both in the development of new products and in terms of providing the required specs of the final product.
