A surfactant composition for a foamed sand including 80 to 99.8 mass % of a compound (A) represented by formula (1); 0.1 to 10 mass % of a compound (B) represented by formula (2); and 0.1 to 10 mass % of an amphoteric surfactant (C):RO-(EO)—SOM  (1)wherein Rrepresents a hydrocarbon group having 6 to 22 carbons, EO represents oxyethylene group, n is 1 to 10, and Mrepresents an alkali metal, an alkaline earth metal, ammonium or an organic ammonium;RO—SOM  (2)wherein Rrepresents a hydrocarbon group having 6 to 22 carbons, and Mrepresents an alkali metal, an alkaline earth metal, ammonium or an organic ammonium.

Surfactant composition for foaming sand

There is provided a toner for developing electrostatic images, including an external additive and colored resin particles containing a binder resin, a colorant and softening agents. The colored resin particles contain a monoester compound A represented by formula (1) and a monoester compound B represented by formula (2) as softening agents. A content of the monoester compound A is in the range from 95 to 99% by mass, a content of the monoester compound B is in the range from 1 to 5% by mass, and a content of the softening agents is in the range from 10 to 30 parts by mass, with respect to 100 parts by mass of the binder resin. Formula (1) is R&#x2014;COO&#x2014;R. Formula (2) is R&#x2014;COO&#x2014;R.

Toner for developing electrostatic images

The present invention provides a refrigeration lubricant composition that have necessary properties such as compatibility with a hydrofluorocarbon refrigerant, thermal stability, hydrolytic stability and low-temperature fluidity, and good lubricity, and has high stability under low temperature conditions so that crystals are prevented from being precipitated over a long term. The refrigeration lubricant includes an ester obtained from a mixed alcohol and a mixed carboxylic acid, wherein the mixed alcohol consists of 65 to 99.95 mol % of pentaerythritol and 0.05 to 35 mol % of dipentaerythritol, the mixed carboxylic acid consists of n-pentanoic acid, n-heptanoic acid, and isononanoic acid, the molar ratio of the n-pentanoic acid to the n-heptanoic acid is 0.3 or more and 10 or less, and the isononanoic acid is contained in the mixed carboxylic acid at a ratio of 10 mol % or more and 45 mol % or less.

Refrigeration lubricant composition

A refrigeration lubricant composition comprises an ester obtained from a mixed alcohol and a mixed carboxylic acid as a main component. The mixed alcohol comprises 65 to 99.95 mol % of pentaerythritol and 0.05 to 35 mol % of dipentaerythritol, the mixed carboxylic acid comprises 25 to 55 mol % of monocarboxylic acid having 5 to 8 carbon atoms and 45 to 75 mol % of isononanoic acid, and the composition has a hydroxyl value of 5.0 mgKOH/g or less and an acid value of 0.05 mgKOH/g or less.
