Abstract (en)

[origin: WO9601915A1] A solvent composition for parts cleaning is improved by addition of an additive composition comprising at least one aromatic, aliphatic or alkaryl sulfonic acid or salt thereof or an esterified polyol or an alkyl phenol formaldehyde resin which has been modified to include alkoxy solubilizing groups. The additive composition provides agglomeration and accelerated settling of contaminant particles in the solvent cleaning composition.
