Included is a rubber composition for tires, including: a rubber component; a phenylenediamine antioxidant; and a masterbatch, the masterbatch containing a specific nonionic surfactant and a silica having a BET value of 40-250 [m.sup.2]/g at a mass ratio of 1:5 to 1:0.15, the rubber component containing a diene rubber in an amount of 70-100% by mass per 100% by mass of the rubber component, the rubber composition including, per 100 parts by mass of the rubber component, 1.0-10.0 parts by mass of the phenylenediamine antioxidant and 0.1-5.0 parts by mass of the nonionic surfactant introduced in the form of the masterbatch.
The formulation is comprised of a nonionic surfactant (an alkyl polyglucoside); dispersing agent (sodium polyacrylate, sodium carboxymethyl cellulose, or sodium carboxymethyl inulin); builder agent (carbonate); enzyme stabilizer (glycine); an enzyme (a purified thermostable Tl lipase enzyme stable at temperatures between 55[degrees] C.
Nanoemulsions containing 10% oil and 10% surfactant were formed using a spontaneous emulsification method with a 10% oil phase (grape seed oil and orange oil) and 10% surfactants a commercial polysorbate 80, which is a nonionic surfactant and emulsifier often used in foods.
By type, the global surfactants market is classified into cationic surfactant, anionic surfactant, nonionic surfactant, amphoteric surfactant and others.
Nonionic Surfactant. Niosomes are multilamellar vesicles prepared from synthetic nonionic surfactants.
The surfactant used in this experiment was a nonionic surfactant comprising 10% alkyl polyglycoside, 7% EO/PO block copolymer and 83% water that was applied at a constant rate of 1000 ml per ha per irrigation.
(5) In this study, two different surfactants were studied: one nonionic surfactant, an alkyl phenol ethoxylate (Surfactant A), and an anionic surfactant, an amine salt of an alkyl benzene sulfonate (Surfactant B).
The anionic surfactant sodium dodecylsulfate (SDS, 96 %, Merck); cationic surfactant cetylpyridinium chloride (CPC, 99-101 %, Merck); nonionic surfactant Tween-80 (density 1.074 g/[cm.sup.3], Appli Chem GmbH) were used for eluent preparation.
The following figures show the level of ADBAC exhausted as a function of the concentration of the co-formulated nonionic surfactant, polyethylene-oxide 12 (Figure 4) and small quat, tetramethyl ammonium chloride (Figure 5).
The relationship between conductivity of polymer solution and surfactant concentration was shown in Figure 1.ButtheTritonX-100 did not change the conductivity, since the Triton X-100 was nonionic surfactant and did not increase the free charges in polymer solution.
