Soap Making Course

Lesson 1 • Key Ingredients and Their Functions

Identifies oils, butters, lye, and water as core soap ingredients and explains each one's role. Connects ingredient knowledge to predictable, consistent soap outcomes.

Lesson 2 • The Science Behind Soap

Covers saponification, the chemical reaction between fats and alkalis that creates soap. Establishes the scientific foundation for every technique taught in this course.

Lesson 3 • Setting Up a Safe Workspace

Defines ventilation, surface protection, and chemical storage requirements for a soap studio. A properly arranged workspace prevents accidents and supports efficient workflow.

Lesson 4 • Reading and Using Soap Calculators

Teaches students to use lye calculators to determine precise ingredient ratios for any recipe. Accurate calculations are the single most critical skill for safe soap production.

Lesson 1 • Personal Protective Equipment

Details the correct PPE for lye work, including gloves, goggles, and aprons. Wearing appropriate protection is non-negotiable before any lye is measured or mixed.

Lesson 2 • Measuring and Mixing Lye Solutions

Covers the correct sequence for dissolving lye in liquid, including temperature management. Proper mixing technique prevents dangerous splashing and uneven concentration.

Lesson 3 • Storing and Disposing of Lye

Establishes protocols for airtight lye storage and safe disposal of unused solution. Correct storage prevents moisture absorption and maintains lye potency over time.

Lesson 1 • Mixing, Pouring, and Molding

Covers stick blending to trace, pouring into molds, and insulating for gel phase. Correct execution at this stage determines bar texture and appearance.

Lesson 2 • Formulating a Basic Recipe

Guides students through building a balanced beginner recipe using common oils. A well-formulated recipe produces a bar that is hard, cleansing, and skin-conditioning.

Lesson 3 • Cold Process Method Overview

Introduces the cold process workflow from oil melting through unmolding. Understanding the full sequence prevents errors at each stage of production.

Lesson 4 • Curing Cold Process Soap

Explains the curing process, during which water evaporates and saponification completes. Proper curing produces a harder, milder, longer-lasting bar.

Lesson 1 • Formulating Hot Process Recipes

Covers oil selection and superfat adjustments specific to hot process production. Higher superfat is added after cook to preserve skin-nourishing properties.

Lesson 2 • Introduction to Liquid Soap

Explains how potassium hydroxide and a higher water ratio produce a paste that dilutes into liquid soap. Liquid soap chemistry differs fundamentally from bar soap chemistry.

Lesson 3 • Hot Process Method Fundamentals

Introduces the hot process workflow using external heat to complete saponification before molding. Hot process soap is usable sooner than cold process soap.

Lesson 4 • Diluting and Finishing Liquid Soap

Teaches dilution ratios, pH adjustment, and preservation of finished liquid soap. Correct dilution determines viscosity, clarity, and shelf stability.

Lesson 1 • Carrier Oils and Their Properties

Profiles key carrier oils by their fatty acid composition and contribution to soap quality. Oil selection determines lather quality, hardness, and skin feel.

Lesson 2 • Milk and Alternative Liquids

Explains how replacing water with milk, aloe, or herbal tea affects saponification and bar properties. Alternative liquids add nutrients and affect color and scent.

Lesson 3 • Butters in Soap Formulation

Examines shea, cocoa, mango, and kokum butters and their effects on bar hardness and skin conditioning. Butters add luxury feel but require careful superfat management.

Lesson 4 • Designing a Balanced Oil Profile

Teaches students to use soap quality ranges to evaluate and adjust a recipe before production. A balanced profile achieves target values for hardness, cleansing, and conditioning.

Lesson 1 • Essential Oils in Soap

Examines which essential oils survive saponification and retain scent through cure. Flash point, usage rate, and acceleration risk determine essential oil suitability.

Lesson 2 • Synthetic Colorants and Oxides

Introduces lab-certified micas, iron oxides, and ultramarines for consistent, stable color results. Synthetic colorants offer predictability that natural options cannot always provide.

Lesson 3 • Natural Colorants in Soap

Covers plant-based colorants including clays, oxides, and botanical powders and their stability in soap. Natural colorants vary in intensity and may shift during saponification.

Lesson 4 • Fragrance Oils and Blending

Covers fragrance oil selection, behavior testing, and blending techniques for complex scent profiles. Fragrance oils must be tested before full-batch use to avoid acceleration or ricing.

Lesson 1 • In-the-Pot Swirl Techniques

Covers dividing batter, adding multiple colors, and swirling within the mold for marbled effects. In-the-pot swirls are beginner-friendly and produce dramatic results.

Lesson 2 • Embeds and Inclusions

Introduces pre-made soap embeds placed inside or on top of bars for dimensional design effects. Embeds must be fully cured before use to prevent moisture issues.

Lesson 3 • Specialty Techniques: Spoon and Drop Swirls

Covers spoon plop, drop swirl, and peacock swirl techniques for surface and internal patterning. These techniques require precise trace and practiced hand movements.

Lesson 4 • Layered and Striped Soap Designs

Teaches timed pouring of sequential layers to create clean horizontal stripes and gradient effects. Layer adhesion depends on timing and batter temperature management.

Lesson 1 • Batch Records and Documentation

Introduces batch record systems for tracking ingredients, quantities, dates, and test results. Documentation supports traceability, recall management, and recipe refinement.

Lesson 2 • Establishing Quality Standards

Defines measurable quality criteria for finished soap including pH, weight, appearance, and scent. Consistent standards enable reliable product evaluation and customer trust.

Lesson 3 • Troubleshooting Common Defects

Diagnoses and corrects defects such as soda ash, ricing, separation, and false trace. Understanding root causes prevents recurring problems across future batches.

Lesson 4 • Workflow Efficiency and Batch Planning

Teaches production scheduling, ingredient pre-weighing, and workspace organization for efficient output. Efficient workflow reduces errors and increases batch throughput.
