Application Of Titanium Dioxide In Sunscreen Products

Ultraviolet radiation consists of light waves that are harmful to the human body. Excessive exposure causes skin redness, heat discomfort, premature ageing and loss of firmness, thereby increasing the risk of skin cancer. Given rising public awareness of these effects, research and production of sunscreens have increased both domestically and internationally. This article examines the use of Titanium Dioxide in sunscreen products.

Titanium Dioxide in Sunscreen Products

Historically, sunscreens mostly utilised organic compounds such as Benzophenones, Salicylates, p-Aminobenzoic Acid and Cinnamic Acids. However, these compounds are unstable and may cause toxicity and irritation. Excessive use may result in chemical allergies and elevate the risk of skin cancer. Nano-Titanium Dioxide has been increasingly adopted as a mainstream sunscreen agent.

Nano-Titanium Dioxide is an inorganic component. It offers chemical stability and thermal stability and provides decolourisation and coverage. It disperses easily and is non-toxic, odourless and non-irritant. The component is safe for use and performs sterilisation and deodorisation.

Ultraviolet light is categorised by wavelength into short-wave, medium-wave and long-wave bands. Short-wave ultraviolet rays possess the highest energy but are blocked by the ozone layer. Consequently, medium and long-wave ultraviolet rays are generally harmful to human health.

Due to its small particle size and high activity, Nano-Titanium Dioxide absorbs, emits and scatters ultraviolet radiation. This effect enables it to block medium and long-wave ultraviolet rays effectively.

Furthermore, the final product demonstrates high transparency due to the fine Nano-Titanium Dioxide particles. Consequently, cosmetic formulators widely prefer Nano-Titanium Dioxide and have gradually replaced some organic ultraviolet protectants. The product development record indicates market potential.
