Conservantes farmacotécnicos utilizados em produtos dermocosméticos magistrais.

Abstract

With the history of beauty’s culture since the early days, cosmetics are always present in the human being's life and, over time, the famous dermocosmetics emerged, which are distinguished by having pharmacological actives in their composition, acting in this way not only in the aesthetic part, but promoting health and well-being to the consumer. With all this progress, more and more companies in this field specialize and improve their products, seeking to offer the consumer a stable, safe and effective formulation.  To ensure greater safety and stability of the formulation to be prepared, it is extremely important that microbial agents are not able to proliferate in the product, and for that, preservative agents are added, which may be of natural or synthetic origin.  The present work seeks, through a bibliographic review, to present the main characteristics of these agents most referenced in the researched literature for dermocosmetic formulations, their benefits and possible harm, thus collaborating with the discernment as to the best choice for a particular formulation.  The following preservative agents will be discussed: Benzoic Acid, one of the first approved by the FDA; Sorbic Acid, which may be of natural origin; Phenoxyethanol, which can be derived from green tea or synthesized in the laboratory; the famous Parabens, preservatives used on a large scale in the market; and Triclosan, an agent widely used in various personal care products, such as deodorants.
