Organic Sunscreen or Chemical Sunscreen that can block UVA light in the wavelength range of 320-390 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 . 

DHHB prefers to call the trade name Uvinul A Plus, this product is not produced by the manufacturer Uvinul A Plus, this product is guaranteed to be as pure as Uvinul A Plus, orders over 10kg, the company provides a free SPF testing service for orders over 10kg. 20kg Test the purity of substances with GCMS for free with every order.

DHHB is used in expensive high-end sunscreen products because of its high effectiveness. And it is very stable in terms of protecting against UVA light. It is recommended that DHHB be used in sunscreen products that are used on the face only. 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. Although the nature of the product (It may give whiteness - difficult to blend - there is a chance of separation) It cannot be equivalent to DHHB. DHHB does not cause whiteness. Creamy texture, easy to spread And easy to mix, no separation problems.

Summary of DHHB features

-It is an organic sunscreen that can block UVA well and is highly stable. even under sunlight There is no need to use other sunscreens in the formula to increase stability. This is different from Avobenzone. Although it blocks UVA well, it is not stable. 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.

-Although unable to protect against UVB light, when used together with other types of organic UVB sunscreens It can help increase the SPF (UVB light protection) value even more.

DHHB is a highly effective UVB-specific sunscreen. When comparing the value of Specific Extinction E1%/1cm

For UVB: DHHB is not effective in blocking UVB when used alone, but has the ability to boost SPF values with other UVB sunscreens when used together in a formula. (Please see additional details below)

DHHB has the ability to add SPF to the UVB sunscreen in the formula (SPF-Booster).

From the research results it was found that In formulas that use DHHB together with other UVB sunscreens such as OMC, increasing the use of DHHB from 2.5% to 10% will increase the SPF value of the formula (which is mainly obtained from OMC) by 2-3 times.

Join to get SPF of at least 25.
