“…The proton peaks at 6.838 ppm can be identi ed as the characteristic peaks of DA. In the spectrum of DA-HA, the hydrogen proton of the benzene ring signal at 6.861 ppm and the methyl proton signal of HA at 2.019 ppm preliminarily con rmed the composition of DA-HA [23,38] . The thermal weight loss curves of HA and DA-HA were shown in Figure S1.…”

“…The initial pH of the DA-HA solution was 4.00. The carboxyl groups gradually deprotonated with the increase in pH and reached a fully ionized state when pH was about 5 [23] . The a nity between DA-HA particles and water was gradually enhanced, resulting in poor emulsi cation performance initially.…”

Hyaluronic Acid (HA) is a mucopolysaccharide alternately linked by glucuronic acid and nacetylglucosamine as disaccharide units. This study prepared HA derivative (DA-HA) by modifying sodium hyaluronate with dopamine (DA). DA-HA had unique surface activity. By optimizing the reaction conditions systematically, DA-HA could prepare the emulsion with uniform droplets successfully. When n (COOH) /n (EDC) /n (NHS) was 1/2/4, n (HA) /n (DA) was 1/5, the reaction pH was 5.5, and the molecular weight of HA was 1,350 KDa, the emulsion particles were relatively uniform. The chemical structure of DA-HA was characterize and he results showed that DA was grafted on the HA chain through the amide bond. In addition, the effect of formula composition on the emulsifying performance of DA-HA was studied. The particle size of emulsion decreased as the concentration of DA-HA increased. When the oilwater ratio was 4/6 or 5/5, the emulsion droplets were small and uniform. When the aqueous phase was in an acidic or weakly alkaline condition, the particle size of the emulsion was smaller. The introduction of high salinity will destroy the stability of the emulsion. Meanwhile, DA-HA also had good moisturizing property and biosafety, which greatly expanded the application of HA in cosmetics.

“…Glycine has special surface activity, low toxicity and high biodegradability, so it is suitable for use in personal care products such as shampoo and body wash (Rajput et al, 2022; Zhao et al, 2019). HA is a natural polysaccharide composed of N‐acetyl‐D‐glucosamine and D‐glucuronic acid units (Liu et al, 2022). Due to its regulatory role in wound repair and re‐epithelialization processes, as well as its stimulation of collagen production, it is widely used as an anti‐wrinkle agent and dermal filler.…”

The mixed system of sodium cocoyl glycinate and sodium hyaluronate (HA) with different mass concentrations and relative molecular weights was investigated by the surface tension method. All the curves of surface tension versus logarithm of concentration (γ‐lgc curves) of sodium cocoyl glycinate‐HA mixed system displayed the properties of double platform. The critical micelle concentration (cmc) of sodium cocoyl glycinate was 1.690 g/L at 25°C. The two inflection points of the γ‐lgc curves corresponding to the cocoyl glycine‐HA mixed system were cac (the critical aggregation concentration) and cmce (the extended cmc of sodium cocoyl glycinate), and cac < cmce < cmc. With the change of the mass concentration and relative molecular weight of HA, the cac values were almost constant. However, cmce increased with the increase of the mass concentration of HA at the same HA molecular weight. For the HA of molecular weight of 800 and 260000 Da, the mass concentration of HA increased from 0.05 to 0.4 g/L, and the cmce value increased from 1.199 to 1.390 g/L and 1.102 to 1.330 g/L, respectively. When the mass concentration of HA remained the same, the change in the relative molecular weight of HA had little effect on the cmce value. For the mixed system of sodium cocoyl glycine −0.1 g/L HA, when the concentration of NaCl was 2 g/L, the salt enhancement effect was dominant. When the concentration of NaCl was 4 to 8 g/L, the salt weakening effect was dominant. It is indicated that HA can improve the chemical properties of sodium cocoyl glycinate at a certain concentration, thus improving the cleaning, foaming, and foam stability of sodium cocoyl glycinate.

Hyaluronic acid (HA) is a mucopolysaccharide alternately linked by glucuronic acid and n‐acetylglucosamine, which is usually used as a moisturizer in cosmetics. In this study, HA derivative (FA‐HA) was prepared by modifying sodium hyaluronate with ferulic acid (FA). The chemical and morphological structure of FA‐HA were characterized by UV, FTIR, 1H‐NMR, DLS and TEM. The results showed that FA was grafted onto HA chains via ester bonds and self‐assembled into nanoparticles in aqueous solution. The introduction of FA endowed the nanoparticles with antioxidant function. The FRAP value of 10 mg/mL FA‐HA was 1.985 mM, and the clearance rate of O2−, DPPH+ and ABTS+ could reach 83.13%, 88.86% and 99.48% respectively. Moreover, FA‐HA can be used as Pickering emulsifiers to stabilize the emulsion. The results showed that the size of emulsion droplets decreased as the concentration of FA‐HA increased. When the mass ratio of oil to water was 7/3, the emulsion droplets were the smallest. The addition of sodium chloride will increase the size of emulsion droplets, destroying the stability of the emulsion. In addition, FA‐HA was also universal and was capable of emulsifying alkanes, esters, and natural oils, which was expected to be applied in the cosmetics and food fields.
