Viscosity drift control in overbased detergents |
| abstract |
Viscosity increase or drift occurs in overbased detergents 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. Additions of this control agent in amounts of 0.1 to 5.0 % and preferably 0.25 to 1.0 %, by weight effected minimal viscosity drift of no more than about 10 % in detergents stored for about 4 weeks at elevated temperatures of about 37 °C to 82 °C. 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 carboxylic acids such as 12-hydroxy stearic acid. The viscosity drift control agent is particularly effective for highly overbased calcium sulfonates. |
