Recipes
TL;DR: Recipes for cold process soap making range from simple three-oil bases to Castilian, goat's milk or tallow recipes. Beginners should start with a recipe with 30% coconut, 40% olive and 30% sunflower oil.
This section contains recipes for all experience levels - from a three-oil basic recipe to Castile soap with a year's aging, tallow soap following the ancestral pattern, goat's milk or shampoo cubes with SCI surfactants.
Every recipe includes exact gram measurements, SoapCalc calculation and detailed procedure. No guesswork.

Classic recipes
Castile soap — 100% olive oil
The gentlest cold process soap — 100% olive oil, no coconut or palm. Ideal for sensitive skin, babies and face, requires at least 6 months of curing for full lather. Also includes a variant of liquid castile soap with KOH.
Goat milk soap
Conditioning soap with lactic acid from goat's milk. The technique of freezing the milk before adding the lye, two recipes (classic and with higher SF for dry skin), benefits for skin with eczema or psoriasis - all in goat milk recipe.
Tallow soap — ancestral recipe
Beef tallow soap creates an exceptional creamy lather — biocompatible fatty acids similar to human sebum. We'll teach you rendering tallow at home (wet and dry method) with two recipes.
Activated charcoal soap
Deep-cleansing soap for oily and acne-prone skin. Scientific explanation of adsorption vs. absorption, three variants of activated charcoal recipe (gentle, standard, detox).
Special recipes
Special soaps: salt bars, beer, milk
Unusual ingredients transform soap — salt bars (intense cleansing, hardening within 30 min), beer soap (beneficial compounds for skin), variations with different milks. Everything in the special recipes guide.
Liquid soap with KOH
Making liquid soap using potassium hydroxide (KOH). Hot process paste → dilution to liquid soap, consistency, preservation — everything in detail in the liquid soap guide.
Natural herbal soap
Infusion oils transform soap — herbal recipes (calendula, chamomile, nettle), table of natural colorants and their stability in alkaline environment can be found in the herbal recipe.
Advanced and design recipes

Frequently asked questions
How much do recipes differ in oil amounts? Each oil has a different saponification number and contributes differently to hardness, foaming and conditioning. Changing the proportion of oils changes the character of the soap - e.g. 40% coconut makes a hard soap with a thick lather, 100% olive oil makes a soft, mild soap. Always recalculate the NaOH in the calculator.
Can I double or triple the recipe? Yes — a soap calculator will recalculate the NaOH amount automatically. Be careful when preparing the lye solution — larger amounts = more heat. Tempering takes longer.
What if I don't want to add essential oil? No problem - the soap works without fragrance (ideal for allergy sufferers). The finished soap will have a neutral, slightly "soapy“ smell.
How do I know if a recipe will suit my skin? Try the recipe in a small batch (200 g of oils) as a test batch. Age for 4-6 weeks - then you will know if it suits you. Gradually add special ingredients (goat's milk, cocoa butter) and see how your skin reacts.
What super fat would you recommend? 5% is standard — safe for all skin types. For dry skin, increase to 7–10%. For oily skin, decrease to 3–4%.
How long does soap cure? Basic recipes 4–6 weeks, castile 6–12 months, special recipes (milk, herbal) 4–8 weeks. Curing is a physical process — water evaporates, soap becomes harder and lathers better.
