The article deals with consumer behaviour when purchasing green products. It develops theoretical knowledge in the field of antecedents to purchase intention with a focus on the currently neglected consumer chemicals (detergents, cleaning agents and cosmetic products). Based on previous studies, antecedents of purchase intention for green consumer chemicals are identified and the significance of their influence is subsequently verified by empirical research. Confirmatory analysis is based on structural equation modelling of data obtained from a questionnaire survey conducted among 250 consumers. The empirical findings show that the main antecedents of green purchase intention in are environmental concern, green lifestyle and product knowledge. The influence of promotion and community can be regarded as weak to insignificant. The degree of influence of all investigated antecedents depends on the gender, age and level of education of consumers. Increasing the volume of purchasing green consumer chemicals will in particular require provision of more information to consumers to increase their awareness of environmental protection and green products.
