This effective self tanning agent is obtained by bacterial degradation of natural phosphate sugar. It reacts with proteins in the skin thereby forming melatonin like brown compounds within several hours ( allow yourself plenty of time before you plan your hot date) producing a suntanned appearance.
Off-white, clumps , slight odour: odour is a light fruity sweet.
Clumps will take a little longer to solubilise, but if you warm your water you will easily get a 10% solution in a short while. Pic on the left is how it comes to us and the pic on the right is the clumps that you will get.
pH 4-6, soluble in water & alcohol. Insoluble in oils
synonyms dihyxal, otan, oxantin.
Use: Can be added to formulations as is, usual final concentration 2%-10%, DHA may lose its tanning effect or induce discolorations when combined with AHAs, titanium dioxide, zinc oxide, iron oxide pigments, or certain perfumes.
Useage; for the face about 2% is a good rule of thumb. For the body up to 10%.
the question we get asked most is does it work? see the pic - forearm on the right as you look is 12 hours after application (10% concentration). Tip -use an applicator so you get an even look.
(most of our team will notice some colour after just a few hours)
