"I buy green products, do you...?" the moderating effect of eWOM on green purchase behavior in Malaysian cosmetics industry

Abstract

Purpose: In recent years, consumers are moving toward purchasing green cosmetics instead of chemical one. Plenty of cosmetics products are banned globally due to the usage of poisonous substances such as triphenyl phosphate and petroleum. As such, it is needed to shift the conventional purchase behavior to green purchase behavior (GPB) to reduce the negative impact on the environment and health. This study aims to investigate the factors that affect GPB in the context of cosmetics products purchase. Additionally, this study examines the moderating role of electronic word-of-mouth (eWOM) in influencing such green behavior. Design/methodology/approach: This study used value-belief-norm (VBN) theory and elaboration likelihood model as a theoretical basis. By using judgmental sampling techniques, a total of 318 usable responses were gathered through online survey. The structural equation modeling approach using partial least square (SmartPLS, version 3.7) technique was used to test the study hypotheses. Findings: Results reveal that altruistic value and hedonic value both positively affect pro-environmental beliefs, which eventually affect consumers’ personal norms. It is found that hedonic value has a greater influence on pro-environmental belief than altruistic value. Additionally, personal norm also exerts significant influence on GPB. Data also support the mediating role of pro-environmental belief and personal norm. Moreover, the multidimensional eWOM moderates the relationship between personal norm and GPB. Practical implications: The findings from this study provide valuable insights for marketers, academicians and practitioners about the drivers of consumers’ green cosmetics purchase behavior. It will enable marketers to develop better strategies for the green market segment. Social implications: The study findings also contribute to the social aspects by understanding consumers’ purchase behavior toward green cosmetics products. It ultimately promotes to consider a healthier lifestyle and to be concerned about environmental well-being. Originality/value: This study is the first to introduce the eWOM as a moderator in the VBN theory. Moreover, this study contributes to the existing body of knowledge in the field by examining few new linkages; more specifically, considering pro-environmental belief as to the mediator between “hedonic value and personal norm,” as well as the mediating effect of personal norm in the relationship between “pro-environmental belief and GPB.” Moreover, this is a pioneer study to consider eWOM as a multidimensional construct rather than unidimensional, which is new in green marketing literature.
