THE IMPORTANCE OF PRE-FORMULATION IN THE STABILITY OF COSMETIC PRODUCTS

Abstract

Cosmetic products can suffer damage, lose their effectiveness and safety, which justifies the importance of the development stage, in special the pre-formulation phase, in physical, chemical and microbiological stability, since development to compliance with the validated deadline stipulated by the manufacturer. The general objective of this work was to seek information that showed the importance of pre-formulation studies in the stability and reliability of cosmetics, addressing a complex phase of base development, the evaluation of cosmetic stability, factors influencing stability, parameters of stability assessment, stability tests and approval criteria. Therefore, this work was based on some bibliographical reviews in a qualitative way that deal with the theme, available in books, thesis, dissertations, monographs and articles, prioritizing more recent and innovative works. Based on the literature review, it was possible to show the need for a well-designed pre-formulation phase as an essential step to ensure stable, safe and effective cosmetic products.
