The authors suggest a simple environmental-friendly method to obtain the additives with anticorrosion and washing properties. Described method is based on the interaction of hydroxides of the alkaline-earth metals with carboxymethylamine-methylalkylphenol obtained via the reaction of the industrial alkylphenol with formaldehyde and the aminoacetic acid.
The effect of synthesized compounds – calcium and barium salts of carboxymethylamine-methylalkylphenol on the anticorrosion and washing properties of ДС -11 oil has been studied. It was established that they show high anticorrosion and washing performance. In 2.5% concentration of the additive, the corrosion of ДС -11oil is eliminated. The compounds studied do not worsen other properties including the viscosity index and freezing temperature of studied ДС -11 oil.  
It was revealed that the composition from barium salts of carboxymethylamine-methylalkylphenol and ИХП-21 additive shows high anticorrosion, antioxidation and washing properties as well.
