The central research question is: what motivations, perceptions and values underlie the purchase decision for vegan cosmetics among Spanish consumers, and how do they vary according to gender and age? To address this question, the study draws on the extended Theory of Planned Behavior (Ajzen, 1991; Ngo-Thi-Ngoc et al., 2024), green consumer psychology (Peattie, 2010), and Lee's (2022) multidimensional perceived value model. The methodological strategy is qualitative, based on 22 semi-structured interviews with Spanish consumers aged 18 to 50, with a balanced distribution by gender. Data are analysed using Braun and Clarke's (2006) thematic analysis framework, supplemented by direct observation at point of sale. Data collection was conducted primarily in specialist vegan cosmetics stores in Madrid (Lush and Freshly Cosmetics), supplemented by interviews in large-surface and online retail contexts. The findings reveal that the decision to purchase vegan cosmetics is not driven by a single motivation but by a constellation of ethical, environmental and functional values that are articulated differently depending on the consumer's profile. Four consumer archetypes are identified: the ethical activist, the informed-functional consumer, the trend follower, and the circumstantial consumer. Trust in certification labels emerges as a critical variable: most interviewees display a form of "resigned scepticism" towards vegan labelling. Social media —especially TikTok and Instagram— act as the primary gateway for younger profiles, while the influence of the immediate social circle proves decisive for adult profiles. Price sensitivity divides the sample between inelastic consumers, who perceive vegan cosmetics as an investment in health and values, and elastic consumers, for whom the price differential represents the most significant conversion barrier. The study contributes to expanding scientific knowledge on sustainable consumption in the Spanish context, a field in which qualitative research with a national sample is still very limited, and offers practical recommendations for brands in the sector.
