Laminarin, a polysaccharide derived from brown algae, has gained attention for its potential biological activities. However, its application in cosmetic formulations is limited due to its functional properties. To enhance its bioavailability and performance, laminarin was modified through esterification to form laminarin butyl esters (LBE). This study aimed to evaluate the antioxidant, skin-whitening, and anti-wrinkle properties of LBE and assess its potential as a novel ingredient in skincare products. Antioxidant activity was evaluated using in vitro assays, including DPPH and ABTS radical scavenging, both of which demonstrated significant free radical neutralizing capacity. Skin-whitening and anti-wrinkle activities were assessed by measuring the inhibition of tyrosinase and elastase. The results indicated that LBE exhibited significantly higher inhibitory effects than native laminarin, with tyrosinase inhibition reaching 26.7 % (compared to 4.7 % for laminarin) and elastase inhibition at 45.8 % (versus 18.5 % for laminarin). Additionally, LBE showed stronger anti-glycation activity, as it effectively inhibited Amadori products, dicarbonyl compounds, and advanced glycation end-products. These findings provide valuable insights into the modification of laminarin and its potential application in cosmetics, offering a foundation for the development of more effective, bioactive ingredients in the beauty industry.

Sulfonated polyetheretherketone and polyvinylalcohol (SPEEK/PVA) blends under light illumination are capable of producing macromolecular radical anions which can be used for generating metal particles or degrading toxic chemicals. Therefore, modification of textile fabric with SPEEK/PVA blends will enable textile material to develop potentially useful applications. In this work, the cotton fabric was modified by SPEEK/PVA polymeric films via glutaraldehyde (GA) cross linker. The properties of the fabrics such as surface morphology, whiteness, wrinkle recovery, moisture permeability and stiffness were then investigated. It was found that the optimal ratio of PVA to SPEEK was 3 to 1, and the blend film was optically transparent and water-insoluble, which did not significantly alter the performance of cotton fabric.

Although retinol and its derivatives are effective anti-aging substances, they can induce “retinoid dermatitis.” To solve this problem, a novel 4-t-butylcyclohexanol α-lipoic acid ionic liquid (BLA-IL) was prepared and confirmed. Retinol can be directly dissolved into BLA-IL, encapsulated into nanoparticles (NPs) and form retinoid-loaded ionic liquid NPs. In-vivo and ex-vivo studies investigated the developed formulation's safety, transdermal enhancement, and efficacy. Safety assessments revealed that BLA-IL-mediated TRPV1 antagonism was achieved. In particular, IL-NPs increase the amount of retinoid in the skin by 4.3 times compared to the free retinoid and 27 % more than NPs. Based on in vivo and in vitro experiments, BLA-IL synergistically doubled the effect of fibroblast COL-I synthesis, with upregulation to 756.9 %, simultaneously enhancing COL-I, COL3A1, and Elna gene expression and inhibiting MMP-1, reactive oxygen species, and neutrophil aggregation. Clinically, retinoid-loaded IL-NPs significantly improved wrinkles, R2, collagen intensity, ITA°, and l -value compared to free retinoid in volunteers. In conclusion, this study displayed that BLA-IL NPs could promote transdermal delivery and achieve synergistic anti-aging efficacy. It could be a promising technology combining IL and nano-technology in the pharmaceutic and cosmetic transdermal areas.

Retinol is used to manage epidermal and keratin metabolism, promote collagen formation, erase wrinkles for firmer skin, and restore suppleness and smoothness. Retinol can be difficult to store and use owing to the potential for skin irritation, oxidation, and biological ineffectiveness. The linolenic acid and phosphatidylcholine deep eutectic solvent (DES) had a low melting point, high bioactivity, and integrated capsule technology for retinol encapsulation. Safety evaluation tests revealed that the formulated DES-retinol emulsion was less cytotoxic than free retinol, as well as less irritant toward chicken embryos, pig skin, and human patches. In a keratinocyte inflammatory factor inhibition assay, the DES-retinol emulsion reduced monocyte chemoattractant protein-1 expression, indicating the potential to reduce the inflammatory response of the skin to retinol-induced irritation. The DES-retinol emulsion exhibited pro-permeability, anti-wrinkle, firming, and antioxidant characteristics in cellular, skin, and clinical investigations. The DES-retinol emulsion promoted type I collagen production, suppressed matrix metalloproteinase-1 activity, and reduced the release of reactive oxygen species. Consequently, the quantity, size, and depth of wrinkles were substantially improved, along with an enhanced anti-aging effect, heightened skin hydration, increased collagen intensity and flexibility, and diminished retinol-induced irritation. In conclusion, the retinol-loaded linolenic acid and phosphatidylcholine DES emulsion exhibited improved stability, enhanced transdermal efficiency, and notable therapeutic effects.

Extensive research and practice on anti-crease of cotton fabric has been made in the past few decades because of its easy creasing properties. However, it has not achieved a good balance between anti-crease performance, strength loss, hydrophilicity and formaldehyde release until now. In this study, for the first time, α-lipoic acid (ALA) which contains bifunctional groups, carboxyl group and disulfide bond, has been successfully used as an innovative cross-linking agent in the anti-crease functionalization to prepare high crease resistant and hydrophilic cotton fabric without strength loss and formaldehyde release. The mechanism between ALA and cellulose through esterification, disulfide breaking and reconstruction, and anti-crease mechanism based on topological disulfide bridges among cellulosic molecules were illustrated in terms of the characterization analyses of cross-linked ALA and poly(α-lipoic acid). This study provides a completely different idea for the preparation of anti-crease cotton fabric with high strength and hydrophilic without negative environmental impact.

Flammability and wrinkling are major defects that enormously restrict its application of cotton fabric in daily life. Herein, a N-heterocyclic compound with ammonium phosphate ester groups (PNH) was synthesized and served as a cross-linking agent to simultaneously enhance the flame-retardant and anti-wrinkle properties of cotton fabric. Fabric treated by 20 wt% PNH solution (CT/PNH20) possessed a wrinkle recovery angle of 234.8° and an LOI value of 42.7 %. It still self-extinguished during combustion even after 50 washing times, and the deterioration in flame retardancy mainly resulted from the formation of sodium phosphates during washing. Its LOI value after 50 washing times restored to 37.8 % from 27.5 % by a facile ion exchange strategy, revealing remarkable flame-retardant restorability. This work provides new insights into simultaneously enhancing the flame-retardant, anti-wrinkle performances of cotton fabric and restoring the flame retardancy of treated fabric after washing via facile and eco-friendly approaches.

The multifunctional textiles are interesting areas to be researched on. In this paper, the effect of the fiber nanocoating on the wrinkle recovery, air permeability and anti-Ultraviolet (UV) property of different woven fabrics using sol–gel method has been studied. The sol–gel method has various advantages over other methods. Along with these properties, no change in visual appearance has also been discussed in this paper. The dispersion of nanoparticles of titanium was obtained into silica sol. The characterization of nanocoating was done using Field emission scanning electron micrograph (FESEM) and Fourier transform infrared spectroscopy (FTIR) studies. The fabric wrinkle recovery properties, air permeability and anti-UV performance were analyzed using three different immersion timings into the nanosol. The results revealed that both wrinkle recovery properties and anti-UV performance have increased with respect to immersing time of the nanocoating although a slight decrease in air permeability and whiteness index of the fabric was also observed.

Generally, Bombyx mori silk dyeing is performed using acid dyes. However, the color fastness is always unsatisfactory due to the weak binding forces under neutral conditions. In the present work, graft polymerization of α-lipoic acid (ALA) onto silk fibers was carried out using a two-step method. Briefly, ALA was grafted onto the silk fibers, followed by a reduction-oxidation process to form poly(α-lipoic acid) (PALA) on the fiber surfaces, aiming at improving the electronegativity of fiber surface and realizing cationic dyeing. The results implied that the combined treatments promoted the intermolecular crosslinking between fibroin chains, endowing the silk fiber with low zeta potential simultaneously. A thin sedimentary layer on the fiber surfaces was observed for the PALA-deposited silk fibers, companying with a significant increase in the content of sulfur and O/N ratio, which verified the successful graft polymerization. The modified silk fabric exhibited improved dyeability, and the dyeing depth and color fastness was noticeably higher compared to that of the untreated after cationic dyeing. Meanwhile, the newly-built intermolecular disulfide crosslinks imparted a detectable anti-wrinkle effect to the silk fabric. This study provides a facile strategy for modification of silk fabric with improved dyeing behaviors and physical properties.

Cotton is one of the most common natural textile fiber, while the high flammability and easy to crease restrict its applications. Improving the flame retardancy and anti-crease property of cotton fabric is very important for its industrial applications. In this study, phytic acid and chitosan were used to construct bio-based IFR system which was used along with eco-friendly 1,2,3,4-butanetetracarboxylic acid (BTCA) to enhance the flame retardant and crease-resistant properties of cotton fabric simultaneously. The results of LOI and vertical burning indicated that the multifunctional modified cotton fabric would greatly improve the flame retardant properties. The modified cotton achieved the LOI values of over 31% indicating excellent flame retardancy. And the multifunctional modified cotton fabric obtained the CRA over 260° revealing excellent crease-resistant performance. This research provides basis for the development of multifunctional modification of natural cellulosic fibers to improve their flame retardant and crease-resistant properties using bio-based products and eco-friendly polycarboxylic acid.

In this paper, a modified sericin containing active acryloyl groups (MSAA) was prepared by amidation reaction using acryloyl chloride and sericin as raw materials, and its structure was analyzed by FT-IR, fluorescence spectrum, zeta potential and 1 H NMR. The results showed that the active acrylyl groups were successfully introduced into the molecular chains of sericin. Then, MSAA and an alkaline crosslinking agent 1,3,5-triacroylaminohexahydro-s-triazine (FAP) were combined to finish cotton fabric in alkaline condition. Under alkaline condition, the anti-wrinkle effect of cotton fabric could be improved by finishing with MSAA and FAP. By measuring the wrinkle recovery angle, it was found that with the increase of MSAA content, the anti-wrinkle effect of cotton fabric was obviousy improved, without significant impact on the strength and whiteness of the fabric. In addition, the dyeing property and ultraviolet resistance of the finished fabric could be apparently improved.

Silk fabrics have poor resistance to ultraviolet (UV) light and to wrinkles. To improve these properties, we propose a finishing method of coating the silk fabric surface with nano-silica (nano-SiO2). The results show that the UV protective factor (UPF) value could reach a maximum of 84.52 after finishing in 10 g/L nano-SiO2 and 20 g/L silane coupling agent (KH570) solution at 80℃. Moreover, the treated silk fabrics showed improved wrinkle resistance and hydrophobicity. The surface morphology and crosslink action of the treated silk fabrics were characterized by scanning electron microscope, energy dispersive spectrometer and Fourier transform infrared spectroscopy, which proved that nano-SiO2 particles were grafted on to the silk fabric. There was no apparent difference in color between untreated and treated silk fabrics. Thermal stability and cytotoxicity tests showed that the treated silk fabrics had good thermostability and cytocompatibility. The UPF value could be maintained at 77.31 after washing 20 times, which demonstrated that the treated silk fabrics had laundry resistance. Multifunctional silk fabrics with good hydrophobic properties and excellent UV and wrinkle resistance were developed, showing good prospects for their application in self-cleaning, protective and non-ironing clothes.

Machine-washable and antimicrobial substances are the demand for the current wool fabrics. The characteristic of wool fabric is studied with novel self-made azetidinium cationic polyurethane dispersions (PUDs), which used dihydroxyalkyl glycidylamine as the chain extender. Dihydroxyalkyl glycidylamine was synthesized by ring opening with epichlorohydrin and diisopropanolamine. Influences of the cationic PUDs on antibacterial properties, felting shrinkage, and yellowness index of wool fabric are studied. The results show that the antifelting feature of wool fabric with the cationic PUDs is better than the others. It is also found that the wool fabric has a clear antibacterial property. The optimal process has been concluded as follows: the compound PUDs of 50 g/L and curing at 130 °C 5.0 min. The finished fabric has low felting shrinkage after washing for 20 times at 60 °C.
