Water

Other name: Aqua; H2O; Eau; Aqueous; Acqua

Function: Solvent

1. Definition Water:

Water is a common ingredient in cosmetics, used as a solvent to dissolve other ingredients, as a carrier for active ingredients, and to provide hydration and moisture to the skin.

Ethylhexyl Triazone

Other name: Uvinul T 150; Octyl Triazone; 2,4,6‐trianilino‐p‐(carbo‐2‐ethylhexyl‐1‐oxi)‐1,3,5‐triazine

Function: Uv Absorber, Uv Filter

1. Definition Ethylhexyl Triazone:

Ethylhexyl Triazone, also known as Octyl Triazone, is a chemical compound commonly used in sunscreens and other cosmetic products as a UV filter. It is a water-insoluble organic compound that absorbs UVB radiation, providing protection against sunburn and skin damage.

2. Use:

Ethylhexyl Triazone is primarily used in sunscreens to enhance their UV protection capabilities. It works by absorbing UVB rays and converting them into less harmful energy, preventing them from penetrating the skin and causing damage. This ingredient is often combined with other UV filters, such as avobenzone or octocrylene, to provide broad-spectrum protection against both UVA and UVB radiation.

3. Usage Ethylhexyl Triazone:

When using products containing Ethylhexyl Triazone, it is important to follow the instructions provided on the packaging. Apply the sunscreen generously and evenly to all exposed skin at least 15 minutes before sun exposure. Reapply every two hours or more frequently if swimming or sweating. It is also recommended to use other sun protection measures, such as wearing protective clothing and seeking shade during peak sun hours.
