*'''Volatile Fatty Acids (VFAs)''' (acetic, propionic, butyric and valeric acids) are lipid soluble.  They readily diffuse into the squamous mucosal cells of the ''stratum spinosum'' causing similar damage to HCl.

*'''Lactic acid''' may increase the permeability of the squamous mucosa in the presence of VFAs and/or HCl (Andrews et al. 2008).

*'''Exercise:'''blood flow diverted to muscle, compromises mucosal blood flow, also see below
