“…However, the purpose of adding these filters to cosmetic products is not limited to photoprotection. Sometimes, inorganic UV filters are used as a pigment or as an opacifier 16,18 . Not surprisingly, then, the present research revealed that there was a high frequency of inorganic UV filter usage among the cosmetic products designed for use on the face, or as a colouring agent or toiletry.…”

“…Sometimes, inorganic UV filters are used as a pigment or as an opacifier. 16,18 Not surprisingly, then, the present research revealed that there was a high frequency of inorganic UV filter usage among the cosmetic products designed for use on the face, or as a colouring agent or toiletry. Moreover, several UV filters can be used to protect light-sensitive products and their ingredients from the degradation effects of UV radiation (such as colour fading and scent decomposition).…”

“…Apart from its photoprotection property, titanium dioxide can be incorporated as a colourant providing whiteness or opaqueness to various cosmetics products, such as coloured cosmetics, and pressed and loose powders 16 . Besides, titanium dioxide is found in skin cleansers as a colour‐improving agent 18 . When used as a pigment, it may be referred to as titanium white, Pigment White 6, or CI 77891 19 .…”

Background As several reports have raised a variety of environmental, health, and safety issues related to ultraviolet (UV) filters, it is crucial to understand the trends in the exposure of the population to UV filters. Objective To determine the frequency of UV filter usage in sunscreens and other cosmetic products in Thai market. Methods We surveyed the UV filter labelling on sunscreens and cosmetic products sold in the Thai market. In all, 312 sunscreens and 1350 other cosmetic products were investigated. Results Titanium dioxide was the most frequently used UV filter in both sunscreens (66.7%) and other cosmetic products (68.4%). Ethylhexyl methoxycinnamate was the most common organic UVB filter, whereas butyl methoxydibenzoylmethane was the most common organic UVA filter. In sunscreens aimed at children, bis‐ethylhexyloxyphenol methoxyphenyl triazine was the most commonly used UV filter. The most frequent co‐occurrence of UV filters was titanium dioxide and ethylhexyl methoxycinnamate. Conclusions Titanium dioxide was the most commonly used UV filter, which differs from the findings of previous surveys. Knowing the availability and frequency of each UV filter provides valuable information about consumer exposure levels, facilitates refinements of the allergen series in patch testing, and enhances the monitoring of adverse effects of UV filters.
