“…Polyelectrolyte surfactant complexes (PESCs) consisting of polyelectrolytes (PEs) and surfactants of opposite charge have attracted much interest , in the past decades because their extraordinary properties make them useful for numerous applications ranging from detergents, paints, pharmaceuticals and cosmetics to biotechnology and waste water treatment. , Adsorption of oppositely charged surfactant molecules on the PE is strongly cooperative after initial noncooperative adsorption − and occurs above the critical aggregation concentration (CAC), which is significantly lower than the critical micelle concentration of the pure surfactant solutions. ,,, Depending on the chemical nature of the PE and surfactant, the complexes can show a rich variety of morphologies . However, clear solutions are formed if a sufficiently large excess of either PE or surfactant is present, whereas macroscopic precipitates occur around charge equilibrium. − Using double-hydrophilic block PEs (DHBE) with an additional nonionic block can prevent macroscopic precipitation of PESCs around charge equilibrium.…”

Aqueous mixtures of polyelectrolytes and oppositely charged surfactants form clear and homogeneous solutions if either the polyelectrolyte or the surfactant is present in excess. Around charge equilibrium, macroscopic precipitates are formed. Near the phase boundary on the polyelectrolyte-rich side, nanometric polyelectrolyte/surfactant complexes can greatly increase the viscosity of aqueous solutions. This behavior is governed by the composition and chemical nature of the polyelectrolyte and surfactant. Here, we investigate complexes consisting of the polycation JR 400 and two different surfactants, namely, sodium octyl sulfate (SOS) and sodium tetradecyl sulfate (STS), which only differ in the length of their alkyl tail. Using small-angle neutron scattering and neutron spin-echo spectroscopy, we find that STS forms mixed aggregates with JR 400 which results in a pronounced increase in viscosity. Such an increase is not observed for SOS where no mixed aggregates are formed. Comparison with atomistic molecular dynamics simulations shows good qualitative agreement.

“…Eventually, further increases in surfactant concentration result in the dissolution of the coacervate. The dissolution and precipitation process has been used as a tool to enhance deposition of insoluble cationic polymers and anionic surfactant complexes onto hard surfaces (e.g., fabrics) . In this work, the behavior of solutions of modified HECs was explored by monitoring the changes in the transmitted light as a stock laundry detergent solution was titrated.…”

Soil-release polymers (SRPs) are essential additives of laundry detergents whose function is to enable soil release from fabric and to prevent soil redeposition during the washing cycle. The currently used SRPs are petrochemical-based; however, SRPs based on biorenewable polymers would be preferred from an environmental and regulatory perspective. To explore this possibility, we have synthesized SRPs based on hydroxyethyl cellulose (amphiphilic HEC) appended with controlled compositions of hydrophobic and cationic appendages and assessed their cleaning abilities. The results demonstrate that the introduction of hydrophobic lauryl appendages onto the HEC backbone is essential to deliver anti-redeposition and soil-release performance. Conversely, further introduction of cationic groups onto hydrophobic modified HECs had no clear impact on soil-release performance but caused significant disadvantages on anti-redeposition performance. We speculate that this poor performance arises on account of coacervation formation between the cationic HEC polymer and the anionic surfactant in the detergent, negatively impacting soil suspension and suggests that the inclusion of cationic appendages on HECs can ultimately lead to detrimental effects on performance. Interestingly, in contrast to conventional SPRs that exhibit good soil-release performance exclusively on synthetic fabrics, amphiphilic HEC displayed encouraging results on both synthetic and cotton-based textiles, possibly as a result of a good chemical affinity with natural fabrics. This work highlights that the nature and hydrophobic content of HEC ethers are key variables that govern HEC applicability as SRPs, thus paving the way for the design and synthesis of new SRPs.

Kajian Tingkat Iritasi Surfaktan Berdasarkan Nilai Zein pada Sediaan Body Wash

2023

View full text Add to dashboard Cite

Body wash merupakan salah satu sediaan kosmetik pembersih yang umum digunakan untuk membersihkan tubuh yang mengandung surfaktan sebagai salah satu bahan utamanya. Surfaktan sebagai bahan utama yang digunakan dalam sediaan body wash memiliki manfaat sebagai pembasah, pembersih, dan bahan pembusa. Mekanisme surfaktan dalam membersihkan kotoran di kulit yaitu berikatan dengan stratum korneum. Penggunaan surfaktan dalam jangka panjang dapat menyebabkan pembengkakan keratin dalam korneosit, kerusakan struktural pada stratum korneum, meningkatkan Transepidermal Water Loss (TEWL) dan denaturasi protein, sehingga diperlukan sediaan pembersih yang mengandung surfaktan yang aman dan tidak mengiritasi kulit. Penulisan kajian pustaka ini bertujuan untuk mengetahui kemampuan surfaktan dalam mempertahankan stabilitas busa guna membersihkan kotoran di permukaan kulit dan juga mengetahui tingkat iritasi surfaktan berdasarkan nilai zein pada formulasi sediaan body wash. Kajian pustaka ini dilakukan menggunakan metode penelitian secara komparatif dengan mengumpulkan data dari berbagai sumber pustaka yang sesuai dengan kriteria inklusi dan kriteria eksklusi. Hasil dari kajian pustaka menunjukkan bahwa surfaktan mengalami peningkatan stabilitas busa ketika dikombinasikan dengan polimer ataupun saponin dari ekstrak tanaman. Pengujian potensi iritasi surfaktan dengan kombinasi dari berbagai jenis surfaktan anionik, amfoterik, dan non ionik dengan penambahan beberapa zat seperti polimer, ekstrak tanaman, ekstrak dari fermentasi Bacillus, talkum ataupun penambahan alkil poliglukosida menghasilkan potensi iritasi yang lebih rendah jika dibandingkan dengan surfaktan tunggal.
