CRITERIA FOR SELECTING AEROSOL PACKAGING AND DETERMINING THE OPTIMUM QUANTITY OF A PROPELLANT

Abstract

Development of a new generation of functional antiage cosmetics is a most important area of cosmetic industry development. An integral part of such products are biologically active substances (BAS) with essential oils, being among the sources of which. Each essential oil is characterized by a well balanced unique composition of biologically active substances. Development of new cosmetic products consists of correct selection of the required composition of components with required properties and selection of a suitable package, preserving product properties throughout its shelf life. During production of cosmetic products in aerosol package a number of issues are solved, unlike with antiage-products in form of creams in customary tubes. The degree of oxidation-reduction reactions, having negative impact on the properties of essential oils, is substantially reduced. The concentration providing for the optimum degree of evacuation and excess pressure in the packaging are essential issues. The aim of this research is to determine the degree of evacuation of the contents, excess pressure, and mass fraction of a propellant in the product test samples to find the samples of aerosol package with optimum parameters. A number of tests to determine the degree of evacuation of the contents from aerosol package, excess pressure and a mass fraction of a propellant have been performed. The greatest degree of evacuation of products was observed with mass fraction of propellant of 13.79%. Based on the results of the tests for excess pressure in aerosol packaging, it has been found, that with mass fraction of a propellant of 13.79% excess pressure is 0.4 MPa, which was taken as an optimum value. The test showed that the mass of a propellant of 16 g evacuates the product from aerosol package to the maximum extent and does not exceed the acceptable limits for excess pressure (0.2–0.6 MPa)
