Using phase change materials (PCM) is a suitable solution to prevent heat loss. PCM emulsions (PCMEs) have several advantages and are specifically applied in heat exchangers. Here, the formulation of these emulsions, the type of surfactants, and their composition based on freeze–thaw cycle stability are investigated. The Hydrophilic–Lipophilic-Deviation (HLD) platform is used for this purpose. Considering the importance of stability during temperature changes in PCMEs, three types of surfactants that have different behaviors with respect to temperature are used: ethoxylates, ionics, and sugar-based surfactants. By performing freeze–thaw cycles on emulsions made by individual surfactants, after 10 freeze–thaw cycles it was observed that the oil separation in each of the samples containing polysorbate80, AOT, lauryl-myristyl-alcohol-polyethylene-glycol-ether, SDS, sorbitan-monooleate, and decylglucoside occurred at the 2nd, 4th, 6th, 7th, 8th, and 10th-cycle, respectively. Therefore, the sorbitan-monooleate and decylglucoside had better freeze–thaw cycle stability compared to the others because of their non-sensitivity to temperature. We also applied the emulsion cycle stability with two combinations of surfactants: (1) polysorbate80 and sorbitan-monooleate, (2) decylglucoside and sorbitan-monooleate. The former, despite the effect of temperature, showed no oil phase separation in the nine freeze–thaw cycles, but in the latter, the oil phase separation occurred in the 5th-cycle. This study shows that synergism of surfactants is the most important factor in the stability of emulsions. To better explore these emulsion systems, the storage stability, freeze–thaw stability, droplet morphology, and viscosity tests were performed on different samples at various HLD values.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 4","pages":"567-579"},"PeriodicalIF":1.6,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140043945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of isomer and steric hindrance on their micellization in aqueous solution was investigated by surface tension, conductivity, transmission electron microscopy (TEM) and dynamic light scattering (DLS). Si2C-La-COONa with branching CH3 shows a lower γCMC value and higher the CMC value compared with Et-Si2C-COONa. Cy-Si2C-COONa with cyclohexyl (41.6 mN m−1) and Ph-Si2C-COONa with phenyl (43.9 mN m−1) have larger γCMC values due to the distinct steric hindrance and hydrophobicity. In aqueous solution, the aggregation behavior of Si2C-La-COONa, Cy-Si2C-COONa, and Ph-Si2C-COONa is enthalpy-driven. However, the micellization process of Me-Si2C-COONa and Et-Si2C-COONa is governed by the enthalpy-driven at high temperature and entropy-driven at low temperature.

Gemini surfactants, owing to their molecular structure have better surfactant properties than other monomeric surfactants.

In the current study, the synthesis of novel esterquat gemini surfactants was carried out with spacers of varying chain lengths and was characterized using sophisticated instrumental methods. Various surfactant properties including foaming, emulsification, CMC, surface excess, antimicrobial activity and wetting potential using contact angle were analyzed and compared with benzalkonium chloride. It was observed that the CMC as low as 24.79 × 10−3 mM of the synthesized surfactants is potentially lower than that of conventional monomeric surfactants and was found to increase with an increase in spacer chain length. Further, the applicability and evaluation of performance properties of the synthesized surfactants were studied in fabric softener formulation. The water absorbency and whiteness retention of the formulation prepared using 12-6-12 GS was the highest due to its better wettability amongst other synthesized surfactants owing to its higher spacer chain length. To summarize, the surface and anti-microbial properties of the synthesized surfactants vary greatly with the alteration in spacer chain length.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 4","pages":"497-510"},"PeriodicalIF":1.6,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In alignment with the global push towards natural, renewable, and non-toxic materials, BS stands out as an interesting alternative to conventional synthetic surfactants. BS are a type of green surfactants and compared to synthetic surfactants derived from petroleum they are more biodegradable and have low or no toxicity. This work aimed to investigate the suitability of a biosurfactant extracted from the yeast Scheffersomyces shehatae (BS-SS) to be used in cosmetic applications. The cytotoxicity of the BS-SS was tested in fibroblast (L929) and keratinocyte (HaCaT) cell lines and the potential for ocular irritation was assessed by the hen's egg chorioallantoic membrane test (HET-CAM). The cleaning efficiency of the BS-SS was measured as the ability of make-up removal in pig skin. Our results showed that the IC 50 values were 10.49 mg/mL for fibroblasts and 11.77 mg/mL for keratinocytes, and the biosurfactant did not result in hemorrhage, lysis, and coagulation damages in the chorioallantoic membrane, which classifies the biosurfactant solution as non-irritant. Therefore, ocular toxicity and in vitro skin cell toxicity results showed that BS-SS can be tolerable and safe for cosmetic purposes. BS-SS featured promising cleaning properties, similar to the cleansing activity of the 1% SDS solution and of micellar water for lipstick and foundation products. In conclusion, the results indicate its potential use in cosmetic applications.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 5","pages":"801-811"},"PeriodicalIF":1.6,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139771558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current study, two new nonionic surfactants were synthesized to enhance the oral bioavailability of the low water-soluble antifungal drug Amphotericin-B. The hemolysis effect of nonionic surfactants on red blood cells and cytotoxicity against the 3T3 cell line was studied. Both surfactants have shown low hemolysis and cytotoxicity as compared to standard Tween 80. The morphology of drug-loaded niosomes of nonionic surfactants 1 and 2 was studied by using atomic force microscopy (AFM), and both surfactants based vesicles were spherical, while their average sizes were measured by dynamic light scattering (DLS). The average size, zeta potential and polydispersity index (PDI) values of surfactants 1 and 2 were 282 ± 3 nm, −8 ± 1 mV, 0.26 and 287 ± 3 nm, −10 ± 1 mV, 0.24. The drug entrapment efficiency and critical micelle concentrations of nonionic surfactants were determined by using UV–visible spectroscopy. The structures of surfactants 1 and 2 were assessed through single-crystal x-ray crystallographic analysis, while Hirshfeld analysis was performed to study the intermolecular interactions of molecules, as well as the packing behavior of their crystals. The nonionic-surfactant 1 was further tested for antileishmanial activity against Leishmania tropica promastigotes, in both drug-loaded and unloaded niosomal vesicular forms.

Rhamnolipid, a green and safe biosurfactant, was studied from the perspective of rheology to help develop a formulation with natural and effective ingredients for cosmetics. The viscosity of rhamnolipids was investigated by changing pH, concentration and adding additives like inorganic salts (NaCl, MgCl2) and polymers (Carbopol® Ultrez 20, Carbopol® Aqua SF-1, Carbopol® 940 and cationic guar gum), showing that the viscosity of rhamnolipid had a positive correlation with the increase of concentration, a negative correlation with the increase of pH, and that polymers instead of inorganic salts were suitable for thickening rhamnolipid. Further rheology tests indicated that Carbopol® Aqua SF-1 imparted gel properties of rhamnolipid while cationic guar gum determined the liquid properties. In addition, the rhamnolipid-containing moisturizing cream consisting of stearic acid/squalane ratios all showed shear-thinning and gel behavior the same as the commercial ones. Visual appearance and particle size analysis indicated that all formulations exhibited high storage stabilities. The knowledge gained from this study may be useful for designing “sulfonate-free” shampoo and cream with rheological properties that can be tailed for specific commercial cosmetic applications.","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 3","pages":"355-365"},"PeriodicalIF":1.6,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139659262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
