C 13 15 ALCOHOL 4 EO is based on a saturated, predominantly unbranched C13C15 oxo alcohol that consists of ca. 67 % C13 and ca. 33% C15.
C 13 15 ALCOHOL 4 EO conforms to the following structural formula.
RO(CH2CH2O)xH R = C13C15 oxo alcohol x = 4
The numeric product designation denotes the degree of ethoxylation.
C13 15 ALCOHOL 4 EO is manufactured by reacting the C13C15 oxo alcohol with ethylene oxide in stoichiometric proportions.
The ethoxylation temperature is kept as low as possible.
This, combined with the high purity of the feedstocks, ensures the formation of high-performance, low-toxicity surfactants.
C13 15 ALCOHOL 4 EO is a cloudy, colourless liquid at 23°C.
C13 15 ALCOHOL 4 EO tends to form a sediment, but it forms clear solutions at 50°C.
C13 15 ALCOHOL 4 EO is a nonionic surfactant that has established itself in the detergents and cleaners industry, and in many other branches of industry, on account of its pronounced surface activity.
Their main area of application is in industrial, institutional, and household detergents and cleaners.
C13 15 ALCOHOL 4 EO is nonionic, and they can be readily combined with anionic, cationic, and other nonionic surfactants and auxiliaries.
C13 15 ALCOHOL 4 EO is fully compatible with alkylaryl sulphonates, ether sulphates, and other sulphated and sulphonated products.
Synergistic effects can often be obtained, enabling very high levels of performance.
The same applies to mixtures of a cationic product based on dimethyl-n-alkylbenzylammonium chloride and other nonionic surfactants.
The compatibility of the C13 15 ALCOHOL 4 EO with dyes and pigments, protective colloids, thickeners, and other substances with a molar mass in the upper range is also excellent.
C13 15 ALCOHOL 4 EO and other similar nonionic surfactants have been gaining in importance in recent years, for the following reasons.
Some technical cleaners can contain very high proportions of acids, alkalis, salts, and organic solvents.
High concentrations of inorganic salts, bases, and acids can impair the solubility of the C13 15 ALCOHOL 4 EO, but this does not necessarily have any detrimental effect on their surface activity.
C13 15 ALCOHOL 4 EO does not decompose in the presence of electrolytes, but solutions can become cloudy or even separate.
Solutions should only be discarded if they are inherently unstable.
