Ayrampo (Opuntia apurimancis) as a Natural Pigment in Lipsticks: Acceptance Evaluation and Analysis of Determinant Factors

Abstract

The need to use sustainable and non-toxic ingredients drives the use of ayrampo as a natural pigment. The study evaluates the use of ayrampo within cosmetics as a pigment in lipsticks, measuring its impact on consumer acceptance. Logistic regression was used for data processing to identify the key factors that showed that the components related to pigments, fragrance, and texture are the most important. In this evaluation, ayrampo (coefficient =0.18) showed an intermediate impact in sixth place, surpassed by pigment 600 (coefficient 0.59) and Orange Fragrance (coefficient =0.50). To have an indication of the results obtained, the correlation of ayrampo with other components was measured, explaining that the intermediate impact may be since it interacts at the dependency level with high correlations (0.88) with other elements such as beeswax and coconut oil, which have a low impact (coefficients=0). Machine learning techniques such as Random Forest were applied to confirm its importance, which confirmed its intermediate influence, surpassed by pigments and fragrances. The findings reveal the importance and potential of ayrampo as a sustainable natural pigment, but further research is needed with new formulations to ensure acceptance by end consumers
