| | | 1,3-Dihydroxy Usage And Synthesis |
| Chemical Properties | white powder | | Chemical Properties | Dihydroxy has a characteristic sweet, cooling aroma. | | Occurrence | A derivative of naturally occurring starch | | Uses | 1,3-Dihydroxy can be used as artificial tanning agent. | | Uses | 1,3-Dihydroxy (DHA) is a self-tanning agent used in cosmetics
designed to provide a tanned appearance without the need for sun
exposure. It is also a uV protector and a color additive. As a
self-tanning agent, it reacts with amino acids found on the skin’s
epidermal layer. Its effects last only a few days as the color it
provides fades with the natural shedding of the stained cells.
Reportedly, it works best on slightly acidic skin. DHA, when
combined with lawsone, becomes an FDA Category I (approved) uV
protectant. In 1973, the FDA declared that DHA is safe and suitable
for use in cosmetics or drugs that are applied to color the skin,
and has exempted it from color additive certification. | | Uses | These Secondary Standards are qualified as Certified Reference
Materials. These are suitable for use in several analytical
applications including but not limited to pharma release testing,
pharma method development for qualitative and quantitative
analyses, food and beverage quality control testing, and other
calibration requirements. |
