			<content:encoded><![CDATA[<p>(Section 1.7) Presently, about 50% of the surfactants used in the surfactant industry are derived from petrochemical raw materials, and the other 50% are derived from oleochemical raw materials.</p>
<p>Renewable surfactant feedstocks are often <b>perceived</b> as being better for the environment and should therefore be the first choice for environmentally ‘‘friendly’’ products. But is that ‘‘analysis’’ of the situation scientific fact or spiritually pleasing fiction?</p>
<p>From biodegradation, removal by sewage treatment, toxicity, and similar studies indicate that there is little or no measurable difference between surfactants based on petrochemical and renewable raw materials in terms of their direct impact on the environment.</p>]]></content:encoded>

			<content:encoded><![CDATA[<p>Surfactants may also cause problems at later stages of oil processing. In some cases, especially where the extracted crude is recovered in the presence of a great deal of water, the presence of surfactants produces emulsions or microemulsions <strong>that must be broken</strong> and the water separated before further processing can occur. Naturally present surface-active materials in the crude plus any added surfactants can produce surprisingly stable emulsion systems. The petroleum engineer dilemma: (1) surfactants are necessary for efficient extraction, (2) but their presence produces difficult problems in subsequent steps.</p>]]></content:encoded>
