Description
Technical field
The present invention relates to a kind of non-ionic surface active agent compound and preparation method thereof; Be specifically related to nonionic polyoxyethylene series macromolecular surfactant and the little molecular surface active agent of nonionic are carried out composite complex composition and preparation method thereof, a small amount of use of this complex composition can significantly improve emulsion viscosity.The invention belongs to the surfactant compound field.
Background technology
In order to obtain having viscosity higher and stable emulsion; Just require to obtain the higher interfacial film of boundary strength; Be that surface active molecules can have arrangement the most closely on the interface, normal for this reason application surface activating agent is composite to obtain the interfacial film strong, that arrangement is the tightst, mechanical strength is higher that interacts.For example, report is arranged with lauryl alcohol and dodecyl sodium sulfate mixing application, lauryl alcohol can reduce the Coulomb repulsion effect of laurilsulfate base anionic end groups in hybrid films, and it is tightr that hydrophobic chain is arranged; Sorbitan monooleate (Span-80) is an oil soluble surfactant; Anhydrous sorbitol monopalmitate APEO (Tween-40) is the water soluble surfactant active; They join and produce synergy when using, and the polyoxyethylene groups of Tween-40 is that hydrophilic radical and water have strong interaction, and this group also more gos deep into aqueous phase; It is tightr that this just causes the water-repelling agent of two kinds of surfactants in interfacial film, to be arranged, thereby improved the mechanical strength of interfacial film.
Ionization does not take place in non-ionic surface active agent in water, be with hydroxyl (OH) or ehter bond (R-O-R ') be the amphiphilic structure molecule of hydrophilic group.Have non-ionizing characteristics in water just because of non-ionic surface active agent; Determined it superior than ionic surfactant in some aspects; As in water He in the organic solvent, dissolubility preferably being arranged all, stability is high in solution, is not subject to the influence of strong electrolyte inorganic salts and acid, alkali; Can mix use with the other types surfactant, compatibility is good.
Oxygen atom and the hydrogen atom in the water on the ehter bond of the water-soluble back of nonionic polyoxyethylene series macromolecular surfactant form faint hydrogen bond, and polyoxyethylene chain is meander-like, and hydrophilic oxygen atom is positioned at the outside of chain, and ethylidine (CH
2CH
2-) be positioned at the inboard of chain, thereby around the chain just like a hydrophilic integral body.For example; Crodaret is the macromolecule non-ionic surface active agent of one type of bull; Can effectively reduce table, the interfacial tension of system, because the association of hydrophobic grouping on the non-covalent bond effect of spacer group and the molecular backbone between its bigger molecular structure, hydrophilic base makes the ability of its aqueous solution thickening more much better than than the thickening capabilities of little molecular surface active agent; In addition; Its, nonirritant gentle to skin, with characteristics such as the other types surfactant compatibility are good, so nonionic polyoxyethylene series macromolecular surfactant has very wide purposes at cosmetic industry.
The nonionic polyoxyethylene series macromolecular surfactant and the little molecular surface active agent of nonionic of larger molecular weight is composite, and the composition after composite possibly produce many new character that are different from any independent surfactant.The macromolecule and the little molecule that add interact, and make thickening capabilities and the emulsifying capacity of mixed system and stability all be improved; And the existence of more macromolecular nonionic polyoxyethylene series macromolecular surfactant also can influence the physicochemical properties of the little molecular surface active agent solution of nonionic, and great change all takes place physical parameters such as surface tension, critical micelle concentration and aggregation number, Interfacial Adsorption behavior that makes emulsion etc.And, along with the development of petroleum industry, the continuous reduction of oxirane cost, nonionic/non-ionic surface active agent complex composition is having more advantage than other surfactant compound systems in price.
