A Sucrose Fatty Acid Ester-mixed Emulsifier as Stabilizer of Emulsion Systems

Abstract

well established that although they all have layered structures, the occurrence of a sharp peak at 0.41 nm in WAXS pattern is the qualitative characteristic to distinguish α-gel from others, which was attributed to hexagonally packed sub-lattice structure of it 7) . Additionally, the excellent benefits to the skin (including hydration, improvement in the absorbency of actives, etc.) have been described in many researches and attracting wider attention, which were closely linked to the structural resemblance between α-crystalline gel phase and the intercellular lipid of keratinocytes 8) .However, although plenty of studies towards lamellar gel phase mainly composed of poly-ethoxylated alcohol/fatty acid, ionic or cationic emulsifier waxes have been carried out in recent decades 9−12) , yet relatively few information about the gel phase of environmental-friendly and degradable surfactants, like sucrose fatty acid esters, is available 13) .Unlike the polyether and ionized emulsifier proved to be irritating and potentially harmful to the skin to a certain extent, sucrose ester is a kind of biodegradable, safe and

Nanoparticle Betacarotene Formulated in Cetyl Alcohol, Glycerine, Stearic Acid and TEA as Based Cream

“…As a hardener, general concentration used is 2-10% and as an emulsifier concentration of 2-5%. It was well established that there was a predominant and stable α-crystalline gel structure, formed with sucrose fatty acid ester (S1670) and cetyl alcohol, in the pseudo quarter-phase system (Zhou, 2023).…”
