| Summary: | Emollients are multifunctional, water-insoluble ingredients used in cosmetic products. This study aims to define the chemical and physical characteristics and test the activities of a new ester-based emollient, Sharofeel DS (DS), in comparison with other commonly used emollients (fatty alcohols, esters, and silicone emollients). The new entity was synthesized from naturally derived reactants and designed to be utilized in different cosmetic applications, such as skin care, hair care, and makeup. Methods: The emollient was characterized on the basis of its physical properties (Ultraviolet/Infrared (UV/IR) analysis, density, dynamic viscosity, refractive index, surface tension, and contact angle), calorimetric properties by thermogravimetric analysis (TGA) and differential scanning calorimetry analysis (DSC), viscoelastic properties as is and in emulsion, and toxicity tests. According to the results obtained, DS demonstrated density (0.881 g/mL) and viscosity (86 cPs) values comparable to fatty alcohol emollients, with a refractive index (1.457) comparable to fatty alcohol and ester-based emollients and a surface tension (22.53 mN/m ± 0.11 mN/m) similar to the ester-based ones. It proved stable below 308 °C and capable of reducing the loss of internal water from hair strands (−7.5% <i>w</i>/<i>w</i>). Lastly, the toxicity tests proved that DS is safe for topical skincare, haircare, and makeup applications. |
