Essential Soap Making Supplies

If you're interested in trying your hand at making homemade soap, there are some basic supplies you'll need to get started. Having the right tools and ingredients is important for both soap making success and safety. This article outlines the fundamental soap making materials for beginners.

Soap Molds

You'll need soap molds to pour your soap into so it can set up into bars. The best molds for beginners are basic loaf molds made of silicone or wood. Silicone molds are flexible so it's easy to remove the finished soap bars. They also don't require lining like wood molds. Consider getting a mold with a lid to help retain heat while the bars set up.

Lye

Lye is a crucial soap making supply. Combined with oils, lye triggers the chemical reaction called saponification that transforms the ingredients into soap. For safety and accuracy, always use sodium hydroxide lye rather than potassium hydroxide. The two main types of lye are:

  • Sodium Hydroxide Microbeads - fine grains that dissolve quickly in water.
  • Sodium Hydroxide Flakes - larger flakes that take longer to dissolve.

Soap Base Oils

The oils you use will largely determine the quality and properties of your finished soap. Some top soap making oils include:

OilBenefits
Olive OilGentle, moisturizing
Coconut OilLathering abilities
Palm OilHarder bar

Use a combination of oils for best results. Keep in mind your soap should have at least 30% palm, coconut or a mix of the two for a cleansing bar.

Essential Oils & Fragrance Oils

Adding scents to soap is optional, but popular. You can use pure essential oils or manufactured fragrance oils. Essential oils come directly from plants while fragrance oils are synthetically created. A few drops per pound of soap is plenty.

Colorants & Additives

To naturally color your soap, you can use herbs, spices, clays, sea salts and more. Be careful with spices as they may bleed or create discoloration over time. Use micas for vibrant color. Other additives like oatmeal, flower petals or coffee grounds provide visual interest.

Soap Making Tools

You'll need basic kitchen tools like a scale, thermometer, mixing bowls, spatula, spoon and knife. Safety gear like gloves and goggles are a must. A stick blender makes mixing easier. Invest in quality tools for best results.

Following proper soap making methods and using the right ingredients will help you create beautiful, gentle and cleansing homemade soaps.

Essential Oils & Fragrance Oils for Soap Making

One of the great things about handmade soap is being able to customize your bars with beautiful scents. Adding fragrant essential oils or fragrance oils is an easy way to make your soaps smell amazing. But what is the difference between essential oils and fragrance oils when it comes to soap making?

Essential Oils

Essential oils are natural aromatic compounds extracted directly from plants through methods like steam distillation, cold pressing, resin tapping, and solvent extraction. Popular essential oils used in soap making include:

  • Lavender - floral, relaxing
  • Tea Tree - medicinal, green, earthy
  • Peppermint - refreshing, cooling
  • Eucalyptus - clarifying, stimulating
  • Lemongrass - citrusy, uplifting

The main benefits of using essential oils in soaps are:

  • Derived from real plant sources
  • Provide natural scents and therapeutic benefits
  • Are not diluted
  • Seen as more "natural" than synthetic fragrance oils

However, there are some downsides to keep in mind:

  • Can be expensive compared to fragrance oils
  • May irritate more sensitive skin types
  • Some essential oils can accelerate trace or seize when added to soap batter
  • Essential oil scents may fade faster than fragrance oils

Fragrance Oils

Fragrance oils are synthetic scents created in a lab to mimic natural essential oil aromas or produce completely unique complex scents. Popular fragrance oils for soap include:

  • Floral - rose, jasmine, lilac
  • Citrus - orange, lime, grapefruit, lemon
  • Spice - cinnamon, clove, ginger
  • Wood - cedar, pine, sandalwood
  • Vanilla - classic, sweet scent

The main advantages of fragrance oils are:

  • Much more affordable than essential oils
  • Come in a huge variety of scents
  • Typically have better scent retention in soap than essential oils
  • Less likely to accelerate trace or seize soap batter

The drawbacks are:

  • Synthetic rather than natural
  • May cause allergic reactions for some
  • Some fragrances containing phthalates cannot be used in soap

Usage Rates

For both essential oils and fragrance oils, use about 0.5-1 ounce of scent per pound of soap. Any more may lead to the soap irritating sensitive skin. Add the oils after trace once the lye is neutralized. Mix well to fully incorporate.

Tips for Great Scent

  • Blend 2-3 scents for depth
  • Anchor lighter scents with base notes like sandalwood
  • Use more scent in salt bars since salt diminishes aroma
  • Allow 4-6 weeks curing time for fragrance to mellow

By understanding the differences between essential oils and fragrance oils, you can pick the best options for scenting your handmade soaps.

Colorants & Additives for Homemade Soaps

One of the best parts of making your own soap is getting to play with fun colors, textures, and add-ins. There are many options for naturally coloring soap and incorporating exfoliants, flowers, herbs, and more. Here's an overview of working with colorants and additives in your homemade soaps.

Natural Colorants

Many natural ingredients can provide fabulous, vivid colors in handmade soap without using artificial dyes. Some top options include:

  • Clays - Rose clay (pink), french green clay (green), yellow clay (yellow)
  • Spices - Turmeric powder (yellow), paprika (orange), cinnamon (brown)
  • Herbs - Alkanet root powder (purple), rosemary powder (green), calendula petals (yellow)
  • Other - Activated charcoal (black), cocoa powder (brown), madder root (red)

Tips for working with natural colorants:

  • Use 1-2 teaspoons of powder per pound of soap batter
  • Mix the powder with a bit of oil before adding to batter
  • Some spices bleed or morph colors over time

Micas

Micas are colorants made by grinding natural minerals into a fine shimmery powder. They come in a huge variety of intense colors. Use 1⁄2 teaspoon up to 1 teaspoon per pound of oils. Stir well to fully incorporate.

Liquid Dyes

Vibrant liquid dyes are available in just about every color. Liquid dyes are very concentrated so you only need a few drops per 1-2 pounds of soap. Mix them into a bit of oil before adding to batter. Water based dyes may morph or bleed.

Exfoliants

You can create an exfoliating soap by adding scrubby ingredients like:

  • Rolled oats
  • Coffee grounds
  • Sea salt
  • Ground pumice
  • Fine sugar

Use 2-4 tablespoons per pound of oils. Exfoliants may speed up trace so add them last.

Herbs & Botanicals

Dried herbs, flowers, and plants provide natural beauty. Some options include:

  • Calendula petals
  • Chamomile flowers
  • Lavender buds
  • Rose petals

Use 1-2 teaspoons per pound of soap. Sprinkle on top for decoration or mix in. Flowers may turn brown over time.

With endless options, you can create stunning works of soap art using natural colorants and additives. Just remember to keep your measurements precise.

Essential Soap Making Tools

Having the right tools makes soap making much easier and more efficient. Investing in quality equipment helps ensure success and safety. Here are some of the key tools every soap maker needs.

Safety Gear

When working with lye, protective gear is a must:

  • Goggles - protect eyes from splashes
  • Gloves - heavy duty rubber gloves resist lye
  • Mask - avoid breathing in lye dust
  • Apron - keeps clothing protected

Scale

An accurate digital scale is vital for weighing out ingredients in precise amounts, especially the lye and oils. Look for one with a capacity of at least 5 pounds.

Thermometer

A digital thermometer helps monitor the temperature of the oils and lye-water solution. This allows you to soap at the right temp for your recipe.

Stick Blender

A stick blender makes quick work of combining ingredients and reaching trace. Look for one with detachable stainless steel shafts for easy cleaning.

Molds

You'll need molds to shape your soap into bars. Silicone molds are flexible and wooden molds sturdy.

Mixing Bowls

Have a few heat-resistant glass or stainless steel bowls in varying sizes for mixing lye, melting oils, adding colorants, etc.

Spoons & Spatulas

Stainless steel and silicone utensils are essential for mixing and scooping soap batter before it thickens to trace.

With this core set of soap making tools, you'll be set up for success in creating handmade bars!
