The surface and application properties of APGSHS were studied in detail. The results showed that APGSHS showed much enhanced solubility and there for better foaming and detergency properties than APG due to the introduction of sulfonate group. Then, the mildness of APGSHS and commercially available mild surfactants was compared using zein test and hemolysis of red blood cells (RBC) test. APGSHS has higher mildness than other surfactants, such as potassium lauroylglycinate (PLG), lauramidopropyl betaine (LAB), and sodium laurylmethyl taurate (LMT). The mechanism of mildness was investigated by studying the interaction between APGSHS and protein using zein model through micelle behavior and protein structure. It was observed that compared to other anionic surfactants such as sodium fatty alcohol polyoxyethylene ether sulfate (AES) and sodium dodecyl sulfate (SDS), APGSHS possesses a larger hydrophilic head group and causes less damage to the secondary structure of zein. Finally, the effect of different surfactants on the hair keratin loss during washing was evaluated. The results showed APGSHS had a minimal damaging effect on keratin in the hair, resulting in the lowest protein loss.

Towards this vision, bio-based surfactants and biosurfactants are being explored as alternatives to traditional petrochemical surfactants. However, the transition towards these technologies is expected to be gradual, therefore there is a critical need to formulate new biosurfactants in combination with traditional surfactant classes such as alkoxylates, sulfates and amine-oxides to achieve a balance of performance, cost, and sustainability. To this end, we report a study of the impact of sophorolipid biosurfactants on the cloud point of alcohol ethoxylates, and on the surface tension and foaming of alkyl sulfate/amine-oxide mixtures. We make the surprising finding that high-acid sophorolipids can act as highly efficient hydrotropes and increase the cloud point of alcohol ethoxylates. In sulfate/amine-oxide mixtures, models of experimental data suggest that both high-acid and high-lactone sophorolipids can replace 40–50% of the primary surfactants without significant changes to the surface tension or foaming performance.

Many research studies have focused on the use of recycled WFO. These studies are highly promoted because of the need to find new ways of reducing the negative impact of WFO on the environment. One of these studies focused on the production of sophorolipid (SL), a naturally derived eco-friendly glycolipid biosurfactant. Unfortunately, the environmental and societal advantages brought about by the wide-spread use of SL are offset by its high production cost. WFO is a high-volume, inexpensive material that can be used as a substrate for SL production. As such, by utilizing WFO as a feedstock material cost reduction can be realized to improve large-scale application potential. One drawback to the use of WFO is that its physical characteristics are different from fresh oil and its effect on SL productivity (g/day) has not been investigated. This research focused on the effect of acid value (AV), peroxide value (PV), and carbonyl value (CV) of WFO on SL productivity. It was confirmed that SL titers (111.1 vs. 106.7 g/L) did not differ significantly after using either fresh oil (CV <0.01) or WFO, respectively. In addition, this research also confirmed that higher WFO degradation required longer culture periods (from 6 days to 9 days) to reach comparable SL concentrations as that produced with fresh oil.</p>","PeriodicalId":17083,"journal":{"name":"Journal of Surfactants and Detergents","volume":"27 5","pages":"703-710"},"PeriodicalIF":1.6,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141355401","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}

Second, after a 24 h settling time, considered as optimal, the extraction results, that is, residual soluble COD, residual percentage of surfactant in the dilute phase and volume fraction of coacervate at equilibrium, were expressed in terms of temperature and initial surfactant concentration. For each parameter, the results obtained were modeled using the response surface methodology and represented on three-dimensional diagrams.

A thorough analysis of raw materials, highlighting the significance of feedstock sources, and the current biobased surfactants and rhamnolipid biosurfactants production trends, is presented. Key organic reactions for the production of sorbitan esters, sucrose esters, alkyl polyglycosides, and fatty acid glucamines, such as glycosidation, acylation, and etherification, as well as the production of rhamnolipids through fermentation are described.
