<h3>Overview</h3>
<p>Polyethylene glycol (PEG) raw materials are nonionic surfactants synthesized via <strong>ethoxylation</strong>. The general formula is H(OCH₂CH₂)nOH. Key variants include PEG 400 and PEG 600, typically identified by CAS numbers such as 25322-68-3.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceuticals:</strong> Used as excipients in ointments and suppositories for drug delivery.</li>
<li><strong>Cosmetics:</strong> Functions as humectants and solvents in lotions.</li>
<li><strong>Industrial:</strong> Serves as lubricants and plasticizers in polymer processing.</li>
</ul>
<h3>Precautions</h3>
<p>Store in cool, dry places away from oxidizers. While generally safe, high molecular weight grades may cause irritation; use appropriate PPE during handling to prevent skin contact.</p>
