PENA-CORONA, Sheila I. et al. Quality evaluation of non-medicated commercial shampoos for dogs in Mexico City. Veterinaria México OA [online]. 2022, vol.9, e1000.  Epub May 16, 2023. ISSN 2448-6760.  https://doi.org/10.22201/fmvz.24486760e.2022.1000.

This work performed a descriptive analysis of the quality of shampoos for use in dogs that are marketed in Mexico City. Up to now, there is a lack of information in this regard, which is important to facilitate the selection and recommendation of these products by veterinary professionals. Products of 20 commercial brands were studied, to which physicochemical, sensory and performance tests were carried out, in addition to evaluating the content of their labels. The pH of the shampoos varied between 5.6 and 8.4; the viscosity, between 1 131 and 3 102 m Pa·s; the relative density, between 1.002 and 1.099 g/mL and the foam rate between 2.9 and 4.0 min. 95 % of the shampoos formed a closed foam, between 10 and 35 % of the brands presented deficiencies in the labeling. Generally, the physical-chemical and sensory properties of the shampoos brands under study are within the acceptable limits for the line of use in humans. However, the lack of consistency in labeling suggests that it is necessary to improve the supervision of applicable regulations to protect animals and public health.
