Formulation of a hydrating cream containing Echinacea extract as a preservative and antimicrobial agent

The purpose of this article is to investigate the performance of Echinacea extract as a preservative and antimicrobial agent in a hydrating cream. The hydrating cream was prepared by mixing the oil and water phases at a temperature of 75±2 °C. Then, physicochemical and microbial analysis were performed on the prepared cream using different devices. For proper evaluation and a more detailed examination of the prepared cream, each experiment was performed three times (n≥3), and the average data are reported. The results of the prepared cream indicate that it has a high skin absorption capacity, and the Echinacea extract has given it antimicrobial properties. Other advantages of making this hydrating cream include high hydration to human skin, formulation stability, and long-lasting effect without creating a two-phase state. Creams have been evaluated as a primary component of cosmetic products as topical preparations from time immemorial due to their ease of use and removal from the skin. In this article, we report the formulation of a hydrating cream using various ingredients. The results obtained from this article demonstrate that this extract can maintain its properties under accelerated stability conditions for 6 months . Also, the prepared cream can eliminate bacteria over 28 days in an effective antimicrobial preservatives test.
