Efficiency of Laundry Polymers Containing Liquid Detergents for Hard Surface Cleaning

Abstract

Three water soluble laundry polymers were employed for the first time in liquid detergent formulations for hard surface cleaning. The polymers included in the formulations were the sodium salt of maleic acid/olefin copolymer (P1, anionic), polyethyleneimine (P2, cationic), and polyethylene glycol-g-vinyl acetate (P3, nonionic). Commercially available surfactants (C 10 Guerbet alcohol alkoxylate (FAEO), caprylyl/decyl glucoside (APG), and the sodium salt of ethoxylated alkyl ether sulfate (SLES) were chosen to formulate bathroom, kitchen, and all-purpose cleaners, which provide the desired broad of pH range for hard surface applications. Their hard surface cleaning efficiencies were also compared with an amphoteric polymer (amino modified polycarboxylate, P4) as amphoteric polymers are the most suitable structures for hard surface cleaning. The standard test method and the cleaning device, the so-called cleaning robot, were used to investigate the primary cleaning performances and synergies of the chosen polymers in a hard surface cleaners system. Secondary cleaning performance tests, which indicate the effects of the hard surface cleaners on surface modification, were also performed. The results revealed that the formulations containing P3 and P4 gave the better cleaning performance for primary cleaning tests whereas only P4-containing formulations showed the significant results for secondary cleaning tests.

Biorelated Polyelectrolyte Coatings Studied by in Situ Attenuated Total Reflection–Fourier Transform Infrared Spectroscopy: Deposition Concepts, Wet Adhesiveness, and Biomedical Applications

“…In this review, PEL systems at interfaces are outlined, where they play a significant role in modifying and functionalizing substrates of different chemical origin, size, and shape using only their inherent electrostatic and chemical properties and not applying additional chemical bonding features. Numerous examples for industrial applications and developments concerning polyelectrolytes at interfaces are available, such as in personal care (shampoo, − cosmetics, , contact lenses , ), laundry, textiles, paper making, , water treatment by flocculation, , and membrane-based separation − to name only a few. In all these PEL surface-related applications, there are different concepts, ways, modalitities, and options to bring PEL to surfaces in a sustained manner.…”

Nachhaltiges Design von Struktur‐ und Funktionspolymeren für die Kreislaufwirtschaft

“…Sie ermöglichen die Herstellung vieler Güter mit einem im Vergleich zu alternativen Materialien geringeren Energieaufwand, reduzieren als Isoliermaterial direkt die Treibhausgasemissionen beim Heizen, [4] ermöglichen den Bau von Windturbinen für erneuerbare Energien, senken den Energieverbrauch durch die Gewichtsreduzierung von Autos und Zügen [5] oder durch die Verringerung des Luftwiderstands bei Flugzeugen mit strukturierten biomimetischen Folien [6] . Durch Effizienzverbesserung können Funktionspolymere den Energieverbrauch von Prozessen senken [7] und beispielsweise Waschen bei niedrigen Temperaturen ermöglichen [8] . Außerdem verlängern sie die Lebensdauer von Strukturen aus CO 2 ‐intensiven Materialien wie Beton und Stahl durch Beschichtungen und Korrosionsschutz [9] …”

Preparation and Investigation of High-Efficiency Antibacterial Liquid Dishwashing Detergent

“…Detergents are commonly used in domestic and industrial cleaning. They can be classified as hard surface cleaners, laundry detergents, and dishwashing detergents in accordance with their applications [1]. Although food production technology has been modernized, food safety issues continue to receive increasing attention because of the ubiquity of bacteria, fungi, and other pathogenic microorganisms [2,3].…”
