Patent number: 6239084Abstract: Viscosity increase or drift control occurs in overbased detergents in storage over time and particularly at elevated temperatures. Viscosity drift is now controlled by the addition of additive amounts of a compound having an oleophilic group and further having secondary hydroxyl functionality to a detergent in storage prior to incorporation in a finished oil. Additions of this control agent in additive amounts of about 0.1 to 5.0%, and preferably 0.25 to 1.0%, by weight effected minimal viscosity drift of no more than about 10% where the detergent was stored at elevated temperatures of about 37° C. to 82° C. for about 4 weeks. The degree of viscosity drift control is proportional to the amount of control agent added to the overbased detergent. Preferred viscosity drift control agents are alkylated phenols such as dinonyl phenol, vegetable oils such as canola oil and jojoba oil, and hydroxy carboxylic acids such as 12-hydroxy stearic acid.Type: GrantFiled: July 21, 1999Date of Patent: May 29, 2001Assignee: Crompton CorporationInventors: Theo I.
