Organic Sunscreen or Chemical Sunscreen that can block UVA/UVB light in the wavelength range of 290-370 nm can work well with other sunscreens. and is highly stable under sunlight There is no problem of faster deterioration when exposed to sunlight like Avobenzone.

BEMT is used in expensive, high-end sunscreen products because of its high efficiency. And it is very stable in terms of protecting against UVA/UVB light. It is recommended that DHHB should be used only in sunscreen products that are used on the face. Due to the high price If sunscreen products are used on the body It is recommended to use high amounts of Zinc Oxide to protect against UVA light instead as it is cheaper.

Summary of BEMT features

-It is an organic sunscreen that can block UVA/UVB well and is highly stable. even under sunlight There is no need to use other sunscreens in the formula to increase stability. This is unlike Avobenzone , which, although it blocks UVA well, has lower stability. It is necessary to use other sunscreens to help increase stability.

-Can be used with Physical Sunscreen such as Zinc Oxide or Titanium Dioxide without affecting stability. This is different from Avobenzone which cannot be used with Zinc Oxide , Titanium Dioxide and OMC because it will cause Avobenzone to lack stability. This causes limitations in increasing SPF and PA values in formulas because there are limitations in selecting other ingredients that can help increase SPF and PA values, especially OMC , which is a highly effective UVB sunscreen.

BEMT is a highly effective UVB-specific sunscreen covering UVB/UVA I/II compared to Specific Extinction E1%/1cm.
