What incompatibilities can occur with Dihydroxyacetone (DHA)?

DHA is a very difficult substance, which, under the influence of alkali, converts into glyceryl aldehyde through an enol form, which gives rise to the formation of brown-colored oligomers. Glycerylaldehyde can also play a role in the maillardreaction. Poor storage conditions (< 6 ° C) or too high (> 40 ° C) process temperatures give formation of aldehydes, ketones, acids (formic acid), which then set a lower pH. Maximum stability at pH 3-4 to be set with citric acid. The following factors have a negative impact on stability:

1. Heat
2. constituents with nitrogen atom
3. perfumes
4. microorganisms (maximum hygienic precautions in preparation)
5. oxygen-oxidizing agents.

Also Carbopol is out of the question. Given DHA does not give protection against the sun it must be combined with a nitrogen-free solar filter. The choice of the smell fabrics is also critical.

for the rest, it is recommended to test the different ingredients individually for their compatibility with DHA. If we can believe the above, there are a lot of substances incompatible with DHA in your composition!
