Caustic Potash (Potassium Hydroxide, Liquid Soapmaking Lye) - Essentially Natural

<p>
Essentially Natural Caustic Potash (Potassium Hydroxide) is a strong alkali used primarily as a lye for making liquid
soap through saponification. It reacts with fats and oils to create liquid soap and is also used in specific
formulation contexts where an alkaline material is required. This is a highly caustic raw material and must be handled
with strict safety practices. It is intended for technical and formulation use only.

<h4>FAQs</h4>
<p>
Q: Is this the same as sodium hydroxide?
<br>
A: No, potassium hydroxide is typically used for liquid soap, sodium hydroxide is typically used for bar soap.
</p>
<p>
Q: Can I use this to adjust pH in a cosmetic cream?
<br>
A: It is generally too caustic for casual pH adjustment. Use only if you understand the formulation and safety
requirements.
</p>
<p>
Q: Why does mixing lye produce fumes?
<br>
A: Dissolving strong alkalis in water releases heat and can create irritating vapours, ventilation is important.
