Is zinc undecylenate a hormone product?
In clinical use, Zinc undecylenate powder is usually made into ointment for skin diseases. The main components of such ointment are zinc undecylenate, zinc oxide, etc., and do not contain glucocorticoid. 
Therefore, frequent use will not lead to such problems as hormone-dependent dermatitis,but long-term or improper use of compound zinc undecylenate ointment may affect the skin barrier function, such as skin dryness, desquamation and other symptoms. Therefore, skin tests should be carried out before use, especially for people with skin allergies.
In addition, when using pure Zinc undecylenate Ointment, you should pay attention to keep the local area clean and dry, and avoid contact with eyes. If you feel unwell or the symptoms get worse, you should stop using it in time and consult a doctor.

Zinc undecylenate, an anionic surfactant, is a white amorphous powder. Mainly used as a co emulsifier for cream cosmetics, it can also be used as a fungicide for various cosmetics and soaps. Belonging to common additives in daily necessities, quality control of this product is essential in daily production. After receiving the sample, we take about 0.5g of this product, weigh it accurately, add 10mL of 1mol/L hydrochloric acid solution and 10mL of water, boil for 10 minutes, filter while hot, wash the filter residue with hot water, combine the filtrate and wash solution, cool down, add 1 drop of 0.025% methyl red ethanol solution, add an appropriate amount of ammonia test solution until the solution turns slightly yellow, add water to make the total amount about 35mL, then add 10mL of ammonia ammonium chloride buffer solution (pH 10.0) and a little chromium black T indicator, titrate with ethylenediamine tetraacetic acid disodium titrant (0.05mol/L) until the solution turns purple. Red turns into pure blue. Every 1mL of ethylenediamine tetraacetic acid disodium titrant (0.05mol/L) is equivalent to 21.60mg of C22H38O4Zn.
