Some details here.<\/p>\n<h2>What is hot process soap making?<\/h2>\n<p>The <b>hot process soap making <\/b>is a chemical process that turns fats such as oil or butter into soap in the presence of <b>caustic soda<\/b>. What sets it apart is applying heat to the mixture, between 80 \u00b0C and 100 \u00b0C, to speed up the chemical reaction. This technique is used in particular to make <a href=\"https:\/\/new.tchaou-group.com\/en\/top-17-huiles-pour-fabriquer-votre-savon\/\">traditional soaps<\/a> such <b>as Marseille soap<\/b>.<\/p>\n<h2>What are the advantages of hot process soap making?<\/h2>\n<p>The advantages of using the <b>hot process soap-making method<\/b> are many.

Here are the steps:\u00a0<\/p>\n<h3>1 &#8211; Preparing the lye solution<\/h3>\n<p>To make soap by the hot process method, start by <b>slowly pouring the caustic soda into the distilled water<\/b>. Stir gently in a heat-resistant container.\u00a0<\/p>\n<p>This reaction gives off heat and fumes; make sure you <b>work in a well-ventilated place<\/b> and <b>wear protective equipment<\/b> (gloves, face protection and so on).<\/p>\n<h3>2 &#8211; Heating the oils<\/h3>\n<p>Melt the <b>oils <\/b>and natural <b>butter <\/b>over low heat until it reaches a temperature of around 80 \u00b0C. Use the oil of your choice. The choice will depend mainly on what you need. You can therefore use <b>avocado oil, coconut oil and others<\/b><\/p>\n<h3>3 &#8211; Mixing the lye solution and the oils<\/h3>\n<p>Slowly pour the <b>lye solution<\/b> into the melted oils while stirring. Make sure your hands, face and arms are well protected. The mixing should be done when both mixtures are at similar temperatures, between <b>80 \u00b0C and 90 \u00b0C<\/b>.<\/p>\n<h3>4 &#8211; Blending to trace<\/h3>\n<p>Utilisez un <b>immersion blender<\/b> to mix the oil and the soda until you reach trace, a thick texture like pastry cream.<\/p>\n<h3>5 &#8211; Cooking the soap paste<\/h3>\n<p>Transfer the paste to a <b>slow cooker <\/b>or a <b>heavy-bottomed pan<\/b>. Cover and cook over low heat for about <b>1 to 2 hours<\/b>, stirring every 15 to 20 minutes. The paste goes through different phases: <b>pasty<\/b>, <b>translucent <\/b>and glossy.<\/p>\n<h3>6 &#8211; Adding the additives<\/h3>\n<p>Once cooking is finished, remove from the heat and <b>let the mixture cool slightly <\/b>. Add the <b>essential oils<\/b>, <b>colorants <\/b>or other <b>additives <\/b>of your choice.<\/p>\n<h3>7 &#8211; Molding<\/h3>\n<p>Pour the paste into <b>silicone molds<\/b>, tapping lightly to remove air bubbles. Leave to rest for 12 to 24 hours.<\/p>\n<h3>8 &#8211; Unmolding and drying<\/h3>\n<p><b>Unmold the soap and let it dry in the open air<\/b> for a few days to allow excess water to evaporate. That improves the hardness of the soap.<\/p>\n<h2>What precautions should you take when making soap by the hot process?<\/h2>\n<p>The <b>caustic soda<\/b> is corrosive. Always wear <b>gloves<\/b>, <b>protective goggles<\/b> and work in a well-ventilated space to avoid the risks of splashing.\u00a0<\/p>\n<p>Also make sure the <b>oil and soda mixtures<\/b> are at similar temperatures before combining them, to avoid unexpected reactions.<\/p>\n<p>Finally, use <b>utensils in stainless steel, glass or heat-resistant plastic<\/b>.
