FIELD: chemical or physical processes.

SUBSTANCE: present invention relates to a product for use in detergent compositions containing a mixture of calixarene-containing metal compounds which does not contain sulfur and is dispersed in oil, which can be partially presented in form of a salt, or be neutral, or basic, or overbasic. Said calixarene has general formula (I)

in which a) R₁, R₂, R₃ and R₄ are independently selected from hydrogen or linear or branched alkyl with 6 to 18 carbon atoms; b) R₅ and R₆ represent hydrogen atoms; c) n is number of calixarene ring links, which is 5, 6, 8; wherein in at least one of the n calixarene ring links, at least one of substituents R₁, R₂, R₃ and R₄ contains at least one carboxylic acid type group available for reaction with the metal base, in which metal is selected from alkali metals and alkali-earth metals, provided that said carboxylic acid type group is not contained in link of calixarene ring related to salicylic acid. Also disclosed are a detergent composition, a lubricating oil composition, a method of producing detergent compositions.

EFFECT: disclosed product is used in detergent compositions, which have excellent detergent properties and are capable of constantly reducing formation of deposits.
