Green tannins /Avocado oil composites; suncare and skincare materials

Abstract

Soft skin-friendly green-tea tannins/Avocado oil of antiaging creams were formulated. The active ingredients tannins and Avocado oil were extracted from green-tea and avocado skin, respectively. The active ingredients were carefully investigated for their chemical configurations using 1H NMR and ATR-FTIR spectroscopy, crystal structure using XRD pattern, and thermal stability using TGA and DTG thermograms. The antiaging effect of the cream were carefully investigated for their nourishing effect and protection against solar UVB radiation. Physicochemical properties of the antiaging effect of cream were explored through; in-vitro sun protection factor (SPF), which demonstrated medium SPF value capable of UVB absorption to high content. Optimum viscosity values in presence and absence of Carbopol® 940 moisturizer were evaluated and appropriate spreadability and microscale particle size distribution were demonstrated. The antiaging soft material has also demonstrated antibacterial and antifungal activity. As a result, the advantages and the skin-friendly characteristics; nourishing and protection against solar UVB radiation, and antibacterial and antifungal activity can consider the green-tea tannins/Avocado oil a promising antiaging cream, which not only protects but also nourishable with antibacterial and antifungal activities.
