“…3. This was demonstrated and described in a number of studies that cetyl alcohol possesses two melting peaks at around 30-33℃ (crystalline to a-crystalline transformation) and 50-52℃ (α-form to melt transition) 16,20) . And the endothermic sign of α-form to melt transition for cetyl alcohol could also be observed vaguely due to the existence of a small amount of hydrated alcohols (shown in Fig.…”

“…3, HS-50 and HS-75 presented a pronounced endothermic peak at around 49.5-50.0℃ probably corresponding to the melting of hydrated S1670, which was consistent with the rheological findings about S1670 described by Takahashi et al 28) . While HS-25 showed a main squat endothermic peak at around 49.05℃, and it may have something to do with the existence of multi-phase states formed by S1670 along with water at low concentration 16) . As for the DSC melting behavior of pure S1670, HS-100 showed a significant peak at 54.20℃ accompanied with a slight fluctuation (at around 50.30℃) on the left side.…”

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

The aims of this study were to evaluate the biological activities of black Dimocarpus longan Lour. seed extracts and develop a lamellar liquid crystal (LLC). Different solvents, including petroleum ether, ethyl acetate, and 95% v/v ethanol, were used in the maceration of black D. longan seeds. The inhibitory activities on matrix metalloproteinase-1 (MMP-1) and hyaluronidase were evaluated. The irritating potency of D. longan seed extracts was determined using the hen's egg chorioallantoic membrane test. The extract with the strongest anti-ageing activities and no irritant impact was examined for its chemical contents using high-performance liquid chromatography and incorporated into the LLC. Various factors affecting the LLC formulations, including surfactant types and amounts, thickening agent types and amounts, and various oil types, were investigated. The results demonstrated that the ethyl acetate extract (EtOAc) was the most potent inhibitor of MMP-1 (IC50 = 21.7 ± 5.4 µg/mL) and hyaluronidase (oleanolic acid equivalent = 0.44 ± 0.03 g per g extract). Interestingly, its MMP-1 inhibition was equivalent to that of oleanolic acid, corilagin, and gallic acid. Furthermore, its hyaluronidase inhibition was equivalent to that of gallic acid and ellagic acid. Gallic acid, which was the most abundant compound (15.6% ± 0.06% w/w) was suggested as the compound responsible for the biological activities of EtOAc extract. Considering its potential anti-skin ageing properties with no irritation of EtOAc extract, it was incorporated into the most suitable LLC, which was composed of 5% w/w Lexfeel® D5 oil, 0.5% w/w Carbopol® U21, 2% w/w Liquid Crystal Cream Maker, and 92.5% w/w DI water. The LLC containing EtOAc extract presented birefringence under a polarizing light microscope, indicating its crystallinity. The formulation had good stability after heating–cooling cycles in terms of external appearance, crystallinity, viscosity, and pH (5.5). As a result, it is recommended as a potential cosmeceutical formulation for anti-skin wrinkling. It is proposed that more research be conducted on the safety and efficacy of the treatment on human volunteers.
