Terephthalylidene Dicamphor Sulfonic Acid (also known as Mexoryl SL) is a water-soluble white or off-white powder. It has excellent solubility in water and polar solvents, making it a gold-standard filter for lightweight, high-performance sunscreens.
As a chemical sunscreen agent, it primarily absorbs ultraviolet light in the UVA and UVB bands (290-320nm). It converts absorbed light energy into harmless heat energy, protecting the skin from radiation-induced damage.
One of the most effective UVA-absorbing ingredients available, protecting against skin aging, wrinkles, and long-term damage.
Features a low absorption rate through the skin, reducing the risk of systemic side effects and ensuring safety.
Easily incorporated into the aqueous phase and works harmoniously with oil-soluble filters to enhance overall SPF.
Generally well-tolerated by sensitive skin types with a low incidence of allergic reactions or irritation.
This ingredient is dissolved in the aqueous part of cosmetic products and then mixed with other ingredients according to standard production processes. It is adjusted based on the desired protection level (PA/SPF value).
Used in moisturizers and hand creams to provide daily UVA protection during routine care.
Widely used in sun lotions and sprays to achieve high PA values and effective broad-spectrum coverage.
Added to BB creams, CC creams, and makeup primers to protect skin while adjusting tone.
Store in a closed container at a dry place at room temperature.
