In China’s personal care, home care, and detergent raw material sector, 6501 usually refers to Cocamide DEA, also commonly called CDEA or coconut fatty acid diethanolamide. In terms of ingredient classification, it is a nonionic surfactant. It is commonly used in cleaning products such as ...
Nonylphenol ethoxylates (NPEs, also commonly written as NP-n) are a class of nonionic surfactants produced by ethoxylation of nonylphenol (NP) with ethylene oxide (EO) under catalytic conditions. A key feature of NPEs is that the EO (ethoxy) chain length is variable, resulting in a homologous ...
n-octyl-β-D-glucopyranoside (OG / OGP), CAS 29836-26-8, C14H28O6, MW ≈ 292.4 g·mol⁻¹n-octyl-β-D-glucopyranoside a non-ionic alkyl glucoside: a C8 hydrophobe (n-octyl) glycosidically linked to β-D-glucose. It forms small, fairly uniform micelles and is renowned for its high CMC (typically ~18–25 ...
Saponins are amphiphilic glycosides widely produced by plants (and some marine organisms). Each molecule has a hydrophobic aglycone (sapogenin)—typically a triterpenoid (e.g., quillaic acid) or steroid nucleus—covalently linked to one or more hydrophilic sugar chains (glucose, galactose, ...
n-Dodecyl-β-D-maltoside (DDM)—also called lauryl maltoside—is a non-ionic alkyl maltoside:A C12 hydrophobe (dodecyl) glycosidically linked to the disaccharide maltose. It is widely used to extract, solubilize, and stabilize membrane proteins under mild, non-denaturing conditions, and is among ...
Brij™ 35 (also sold as Brij™ L23); Laureth-23; polyoxyethylene (23) lauryl ether; tricosaethylene glycol monododecyl ether. CAS: 9002-92-0. It’s a nonionic ethoxylated fatty-alcohol surfactant derived from lauryl alcohol with an average of ~23 ethylene-oxide (EO) units (often abbreviated ...
Digitonin is a steroidal saponin (glycoside) classed and used as a mild, non-ionic detergent in biochemistry. It’s renowned for specific binding to membrane cholesterol, which underpins its selective permeabilization of the plasma membrane and its classic use in precipitating cholesterol ...
Poloxamers are amphiphilic triblock copolymers with the general formula HO–(EO)_a–(PO)_b–(EO)_a–H (EO = ethylene oxide, PO = propylene oxide). In water they self-assemble into micelles and, for some grades at sufficient concentration, form thermoreversible gels. Commercial families include ...
Non-ionic surfactants are a broad class of amphiphilic molecules that contain both hydrophobic (oil-loving) and hydrophilic (water-loving) segments, but crucially lack ionic charges. Their hydrophilicity arises from poly(ethylene oxide) (EO) chains that hydrogen bond with water, while their ...
Non-ionic surfactants are indispensable tools in modern science, pharmaceuticals, food technology, and cosmetics, where they function as emulsifiers, stabilizers, and solubilizers. Among them, Tween 20 (Polysorbate 20, CAS 9005-64-5) and Tween 80 (Polysorbate 80, CAS 9005-65-6) are two of the ...
