| Further, Mr Knowles knew nothing of the idea of powdered ingredients or particles acting as dispersants in the dry state from his long experience in the agrochemical industry. |
| Although modern marbling techniques employ acrylic paints thinned with specialized dispersants and floated on specially prepared water, the technique is relatively simple. |
| Hence the containment booms, the skimmer boats and the volleys of dispersants. More than 1m barrels of chemicals have been deployed so far. |
| About 1,000 tonnes of oil were spilled from a damaged tank in the Team Castor. 17 antipollution vessels poured dispersants on the oil slick. |
| They include such materials as thickeners, surfactants, defoamers, biocides, and pigment dispersants. |
| Oil dispersants were applied only as a test because there were too many unknowns about their effect on the environment. |
