Análise da rotulagem e do efeito de dentifrícios veganos sobre a massa e a rugosidade de uma resina composta

Abstract

Introduction: the healthy lifestyle, combined with conscious consumption committed to environmental sustainability and respect for animal welfare, adopted by the vegan movement, has directly impacted the consumption of cosmetics in Brazil and around the world. The vegan public, guided by ethical values and a particular way of living, represents an expanding consumer niche. The vegan cosmetics market has expanded its offer beyond beauty products, covering personal hygiene items, such as dentifrices. Objective: to evaluate in vitro the effect of dentifrices labeled as vegan on the mass and roughness of a nanoparticulate composite resin subjected to simulated brushing and to carry out a critical analysis of the labeling of these products. Material and Methods: in vitro study carried out with 60 specimens (CP) of FILTEK Z350XT nanoparticle composite resin, randomly divided into 6 groups (n=10): control group (GC - Colgate® Total 12 Clean Mint) and test groups (GT1 - Colgate® Zero, GT2 - Antiseptic Mint and Tea Tree Toothpaste, GT3 - Natural Tea Tree Lemon and Mint Toothpaste, GT4 - Natural Toothpaste Healthy Teeth Turmeric and GT5 - Natural Chamomile Green Protection Toothpaste). The specimens were subjected to simulated brushing for 6 and 12 months, with mass and roughness being evaluated before and after the brushing periods. Labeling analysis was carried out to identify the composition of the formulations, visual appeals and compliance according to ANVISA specifications. Results: in relation to mass, there was no significant difference between the groups at the initial time and at each of the evaluated times. In the analysis of roughness, in relation to time, it can be observed that for the CG there was no significant difference (p>0.05) after 6 and 12 months of brushing, while the test groups showed different behaviors. After 12 months of brushing, the GT4 group showed greater roughness than GC, GT1 and GT2 (p<0.05) and the GT5 group demonstrated greater roughness than GC and GT1 (p<0.05). The labeling analysis identified the presence of visual appeals alluding to veganism on all packaging of the test dentifrices, varying in terms of the way the information is presented and the seals of the certifying companies. Conclusion: the dentifrices labeled as vegan did not contain seals from certifying companies on the packaging and presented different effects in relation to the roughness of the nanoparticle composite resin after 12 months of simulated brushing. However, the increase in roughness promoted by some of the dentifrices did not imply a significant loss of pasta.
