What is the Sensitivity of my Balance?

Recognize and detect the effects of electrostatic charges on your balance

The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295nm to 315nm, protecting the skin from sun damage. The hydrophobic cyclohexanol portion provides greasiness that prevents it from dissolving in water.
