Learn How to Make Handmade Soap Course

Lesson 1 • Essential Tools and Equipment

Identifies every tool needed for cold and hot process soap making, from stick blenders to thermometers. Proper tool selection prevents contamination and ensures accurate results.

Lesson 2 • First Aid and Emergency Procedures

Covers immediate responses to lye skin contact, eye exposure, and accidental ingestion. Prepares students to act quickly and correctly in any soap-making emergency.

Lesson 3 • Understanding Lye Hazards

Covers the chemical properties of sodium hydroxide and potassium hydroxide and their risks. Safety knowledge here is prerequisite to every hands-on activity in the course.

Lesson 4 • Personal Protective Equipment

Identifies required PPE including gloves, goggles, and aprons and explains proper donning and doffing. Correct PPE use is compulsory before any lye handling begins.

Lesson 1 • What Soap Actually Is

Defines soap at a molecular level and distinguishes true soap from synthetic detergents. Establishes the chemical foundation for all techniques taught later.

Lesson 2 • Overview of Soap-Making Methods

Surveys cold process, hot process, melt-and-pour, and rebatch methods. Helps students select the right method for their goals before diving into technique.

Lesson 3 • Core Soap-Making Terminology

Introduces essential vocabulary used throughout the course, including trace, gel phase, and superfat. Accurate terminology prevents errors in formulation and troubleshooting.

Lesson 1 • Soft and Liquid Oils

Covers olive, sunflower, sweet almond, avocado, and castor oils and their softening and lather-boosting roles. Balancing soft oils prevents soft, sticky bars.

Lesson 2 • Fatty Acid Profiles and Soap Properties

Maps fatty acid types to specific soap qualities such as hardness, cleansing, and conditioning. Understanding fatty acids is the basis for all oil selection decisions.

Lesson 3 • Superfat Strategy and Oil Selection

Teaches how to set superfat percentages and choose which oils to superfat for targeted skin benefits. Superfat decisions directly affect bar mildness and shelf life.

Lesson 1 • Understanding SAP Values

Explains saponification values for common oils and how they determine lye quantity per gram of oil. Accurate SAP values are the mathematical core of every safe recipe.

Lesson 2 • Testing and Validating Recipes

Introduces zap testing, pH strips, and small test batches to confirm recipe safety before full production. Validation prevents wasted materials and unsafe bars.

Lesson 3 • Water and Liquid Calculations

Covers water-to-lye ratios, water discounts, and substituting liquids such as milk or tea. Liquid choice and quantity affect trace speed, gel phase, and final bar quality.

Lesson 4 • Using Lye Calculators Effectively

Walks through popular online lye calculators, input fields, and output interpretation. Calculators eliminate maths errors but require correct inputs to produce safe results.

Lesson 1 • Moulding, Insulating, and Gel Phase

Covers pouring into moulds, insulating to encourage gel phase, and monitoring soap during the first 24 hours. Gel phase produces a translucent, vibrant bar with improved texture.

Lesson 2 • Preparing Lye Solution Safely

Covers weighing lye, adding it to liquid, managing heat, and cooling to working temperature. Correct lye solution preparation is the most critical safety step in cold process.

Lesson 3 • Unmoulding, Cutting, and Curing

Guides unmoulding timing, cutting technique, and the 4–6 week cure process that hardens and mildifies bars. Proper curing is non-negotiable for safe, long-lasting soap.

Lesson 4 • Melting and Combining Oils

Explains melting hard oils, combining with liquid oils, and reaching target temperature before mixing. Proper oil preparation ensures smooth emulsification with the lye solution.

Lesson 1 • Hot Process Fundamentals

Explains how external heat accelerates saponification to completion, producing soap usable within days. Hot process suits fragrance-sensitive formulas and faster production timelines.

Lesson 2 • Melt-and-Pour Base Selection

Surveys available melt-and-pour bases including clear, white, goat milk, and shea and their properties. Base selection determines the final bar's appearance, skin feel, and additive compatibility.

Lesson 3 • Melt-and-Pour Technique and Additives

Teaches safe melting, temperature control, and incorporating colourants, fragrances, and exfoliants into melt-and-pour bases. Overheating destroys base integrity and causes sweating.

Lesson 1 • Fragrance Oils and Scent Blending

Covers fragrance oil selection, usage rates, and behaviour testing before full batch use. Fragrance oils vary widely in acceleration, ricing, and discolouration potential.

Lesson 2 • Synthetic Colourants and Colour Stability

Examines lab-certified colourants, neons, and liquid dyes for vibrant, stable colour in soap. Synthetic colourants offer predictability but must meet cosmetic safety standards.

Lesson 3 • Natural Colourants in Soap

Covers clays, micas, botanicals, and oxides as natural colourant options and their behaviour in cold process. Natural colourants can morph or fade, requiring informed selection and testing.

Lesson 4 • Essential Oils in Soap

Evaluates essential oils for scent retention, acceleration risk, and skin safety at soap usage rates. Many essential oils fade or accelerate trace, requiring formulation adjustments.

Lesson 1 • In-the-Mould Design Techniques

Covers hanger swirl, pencil line, and layered pours executed after batter enters the mould. Mould design techniques require precise timing between pours to prevent colour bleeding.

Lesson 2 • Specialty Soap Styles

Explores salt bars, bastille bars, shaving soap, and shampoo bars as distinct formulation categories. Each specialty style requires adjusted oil ratios, lye types, or curing protocols.

Lesson 3 • In-the-Pot Swirl Techniques

Teaches drop swirl, Taiwan swirl, and spoon swirl executed directly in the mixing container. Swirl success depends on achieving the correct trace consistency before pouring.

Lesson 4 • Textured Tops and Surface Design

Demonstrates peaks, textured tops, mica lines, and embedded soap curls for professional bar presentation. Surface design adds perceived value and brand identity to finished bars.
