The present study deals with the development and validation of a booklet that contains concepts of chemical kinetics, presented from the action of sanitizers for clothes washing. The objective of this study is to analyze the potential and limitations of the booklet, as well as to verify the participation and interaction of students during the use of the material and to evaluate how the association of the action of sanitizers to the concepts of chemical kinetics can help students understand this subject. In order for the work to be developed, after the development of the booklet, a didactic sequence composed of three moments was proposed: raising the students' previous conceptions, teamwork using the booklet and application of the final questionnaire. Through the application of this sequence, some results were obtained: Most of the students were able to conceptualize what chemical kinetics studies after the teamwork using the booklet, in addition, they associated the study of the reaction speed to other examples of everyday life, not limited to the situation presented about the action of sanitizers for clothes washing. Some potentialities of the booklet identified by the students were: accessible and clear language of the text, promotes interactivity and is playful. In addition, the students made suggestions to improve the content of the booklet: use fewer formulas, discuss more theories, and expand the approach of other subjects. With the results, it was possible to realize that the booklet is an attractive material that can be used as a pedagogical support material, containing various subjects in a playful and interactive way.
