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.
. 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.
It involves the mixing of drug, nonionic surfactant
and cholesterol in chloroform/methanol (2:1).
(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.
