TL;DR:<\/strong> This guide maps all problems by production stage: during production (seizing, ricing, lye pocket), after removal (soda ash, softness), during maturation (DOS, sweating) and finished soap (weak foam, irritation). Each problem has a quick description + link to a detailed page.<\/p>\n<\/blockquote>\n

This encyclopedia is a complete reference guide for diagnosing and troubleshooting cold process soap. Each problem is systematically described with causes, differentiation from similar phenomena and solutions.<\/p>\n

How to use this guide<\/h2>\n

The problems are divided into four groups: problems during production, problems after removal from the mould, problems during maturation and problems with the finished soap. A quick diagnostic key and a link to a more detailed page is provided for each problem.<\/p>\n

Problems in production<\/h2>\n

Seizing: the soap solidified immediately<\/h3>\n

What happens:<\/strong> The mass goes from a thin emulsion to a solid, doughy or crumbly consistency within seconds of adding EO\/FO.<\/p>\n

Causes:<\/strong> Eugenol (clove, cinnamon), aldehydes, too hot mass, combination of multiple accelerants.<\/p>\n

Rescue:<\/strong> HP (hot process) - move to a slow cooker at 60-70\u00b0C, cook until ZAP test (neutral on the tongue).<\/p>\n

In detail:<\/strong> Seizing and trace acceleration<\/a><\/p>\n

Trace acceleration: the mass thickens quickly but is controllable<\/h3>\n

What happens:<\/strong> Thickening occurs within 1-3 minutes after adding fragrance or additives (honey, bentonite). The mass is still usable, but the processing window is drastically shortened.<\/p>\n

Causes:<\/strong> See seizing - a milder form. Honey, FO with accelerant components, too strong trace before adding.<\/p>\n

Rescue:<\/strong> Pour quickly or spoon into the mould. For moderate acceleration is enough.<\/p>\n

In detail:<\/strong> Seizing and trace acceleration<\/a><\/p>\n

Ricing: the mass becomes granular<\/h3>\n

What happens:<\/strong> The mass becomes grainy or cheesy - reminiscent of a rice or cottage cheese dessert. The oil and solid phase are separated.<\/p>\n

Causes:<\/strong> P\u0159\u00edli\u0161 velk\u00fd teplotn\u00ed rozd\u00edl mezi oleji a louhovac\u00edm roztokem (>15 \u00b0C), p\u0159id\u00e1n\u00ed FO na p\u0159\u00edli\u0161 horkou hmotu, n\u011bkter\u00e9 FO zp\u016fsobuj\u00ed ricing bez seizing.<\/p>\n

Rescue:<\/strong> Continue mixing - stick blender. Ricing can be mixed back into the emulsion in 90% of cases. If not, HP rescue.<\/p>\n

Lye pocket: liquid in the middle of the soap<\/h3>\n

What happens:<\/strong> When removed from the mold or when sliced, you will find a liquid or gelatinous center with a sharp or soapy burning sensation.<\/p>\n

Causes:<\/strong> Uneven mixing during production, adding lye to oils all at once without sufficient mixing, pouring too quickly before emulsification.<\/p>\n

Rescue:<\/strong> Small pocket - wrap the soap in foil and leave for another 48 h. Saponification completes. Large pocket - HP rescue. Never use soap with lye pocket.<\/p>\n

Zero emulsification: oil floats on the surface<\/h3>\n

What happens:<\/strong> After mixing the lye and oils, the mass does not form an emulsion - the oil and the lye solution separate back.<\/p>\n

Causes:<\/strong> Too large temperature difference, extremely low production temperature, oils were not melted properly.<\/p>\n

Rescue:<\/strong> Heat the mixture on a water bath and continue to stir with a stick blender.<\/p>\n

Problems after removal from the mould<\/h2>\n

Soft or sticky soap: cannot be cut<\/h3>\n

What happens:<\/strong> After 48 h, the soap cannot be removed from the mould or is sticky like rubber when removed.<\/p>\n

Causes:<\/strong> Too much unsaturated oils, excessive water, too high superfat, miscalculation of NaOH, summer production in the heat.<\/p>\n

Solutions:<\/strong> See detailed guide - 6 causes with specific solutions.<\/p>\n

In detail:<\/strong> Soft soap<\/a><\/p>\n

Soda ash: white dusty coating on the surface<\/h3>\n

What happens:<\/strong> A white or grey dusty coating on the surface of the soap that forms in the first 24-72 hours.<\/p>\n

Causes:<\/strong> Contact of the surface with CO\u2082 from the air prior to the conclusion of saponification.<\/p>\n

Security threat:<\/strong> NO - an aesthetic defect, not a safety risk.<\/p>\n

Removal:<\/strong> Steaming or trimming the surface.<\/p>\n

In detail:<\/strong> Soda ash<\/a><\/p>\n

Crack: surface rupture<\/h3>\n

What happens:<\/strong> The soap in the mould cracks longitudinally or radially. Cracks in the centre or sides.<\/p>\n

Causes:<\/strong> Overheating in the gel phase - the soap expanded and then burst. Too fast cooling (summer production in the fridge).<\/p>\n

Security threat:<\/strong> NO - cracking will not damage the soap in any way. It depends on the design whether the burst bothers.<\/p>\n

Prevention:<\/strong> Avoid overheating (honey, sugar in the recipe). Do not throw the mould suddenly into the refrigerator.<\/p>\n

Soap is too brittle or crumbly<\/h3>\n

What happens:<\/strong> The soap crumbles or breaks when sliced, instead of slicing smoothly.<\/p>\n

Causes:<\/strong> Too low production temperature (struggles with solidification), too low content of conditioning oils, overheating caused anomalous texture, linseed or hard palm oil in high percentage.<\/p>\n

Solutions:<\/strong> Check the SoapCalc \"iodine“ score - too low = soap is too hard. Increase the proportion of olive or castor oil.<\/p>\n

The soap cannot be removed from the mould<\/h3>\n

What happens:<\/strong> The soap sticks to the mould or tears when removed.<\/p>\n

Causes:<\/strong> Silicone molds - usually easy to remove, but too soft soap tears. Wooden moulds without lining - soap sticks.<\/p>\n

Solutions:<\/strong> Silicone - put the mould in the freezer for 30-60 min. Wooden moulds - always line with baking paper or foil.<\/p>\n

Problems during maturation<\/h2>\n

DOS: Dreaded Orange Spots<\/h3>\n

What happens:<\/strong> Orange or brown spots, irregular, on the surface or in cross-section. Rancid odour.<\/p>\n

Causes:<\/strong> Oxidation of unsaturated fatty acids - rancid oils, metal ions in water, improper storage.<\/p>\n

In detail:<\/strong> DOS spots<\/a><\/p>\n

Sweating: droplets on the surface<\/h3>\n

What happens:<\/strong> Droplets of liquid on the surface of the soap - reminiscent of sweat. The soap is otherwise solid.<\/p>\n

Causes:<\/strong> Glycerin in soap is a strong humectant - in a high humidity environment it absorbs moisture from the air and forms droplets. Soap with honey or sugar is more susceptible.<\/p>\n

Security threat:<\/strong> NO - soap is perfectly safe.<\/p>\n

Prevention:<\/strong> Store dry or wrap in transparent film in the rainy season.<\/p>\n

Soap odour: rancidity, chemical or pungent smell<\/h3>\n

What happens:<\/strong> Soap smells rancid, pungent chemical or unpleasant odor.<\/p>\n

Causes:<\/strong> Rancidity (oxidation) - see DOS. Excessive overheating during production. Incorrect amount of lye (too little - free oil, too much - lye did not react).<\/p>\n

Solutions:<\/strong> Rancid soap - discard or HP rescue. Meadow smell - leave for another 2-4 weeks, the smell will fade with saponification.<\/p>\n

White stripes or \"ghost swirl“<\/h3>\n

What happens:<\/strong> White or light spiral patterns in the cross section of the soap, although multi-coloured soap was not intended.<\/p>\n

Causes:<\/strong> The soap did not go through an even gel phase - the center gelled, the edges did not. White layer (edge) vs transparent (gelled center) = ghost swirl.<\/p>\n

It's a deliberate technique<\/strong> (see Swirl techniques<\/a>), but if it occurs unintentionally - the prevention is the even temperature of the mould.<\/p>\n

Problems with ready-made soap<\/h2>\n

Soap does not lather well<\/h3>\n

What happens:<\/strong> Soap lathers poorly, the lather is watery or thin.<\/p>\n

Causes:<\/strong> Too little coconut or castor oil (both contribute to foaming). Hard water (calcium blocks foaming). Too low in lauric acid.<\/p>\n

Solutions:<\/strong> Add 5-10% castor oil to your next recipe. Always use softer water for foam testing.<\/p>\n

Soap leaves a \"waxy film“ in the hair<\/h3>\n

What happens:<\/strong> After washing hair with CP soap shampoo cube, hair is heavy or waxy.<\/p>\n

Causes:<\/strong> Soap stearates react with calcium in hard water to form soap scum, which gets trapped in the hair.<\/p>\n

Solutions:<\/strong> Acid rinse (apple cider vinegar diluted 1:10). Filter hard water.<\/p>\n

In detail:<\/strong> Shampoo bars<\/a><\/p>\n

Soap irritates the skin<\/h3>\n

What happens:<\/strong> Burning, itching or redness after using CP soap.<\/p>\n

Causes:<\/strong><\/p>\n
