But if you’re ready to take your creations to the next level, you might want to experiment with additives. Additives can enhance the texture, appearance, and benefits of your soap, but not all additives are suitable for melt and pour bases. Some can affect the texture, performance, or safety of your soap.
In this guide, we’ll walk you through the additives you can and cannot add to melt and pour soap, as well as tips on how to use them effectively. Whether you’re looking to add moisturizing properties, vibrant colors, or a relaxing fragrance, we’ve got you covered!
1. What Are Soap Additives?
Soap additives are ingredients that are mixed into the soap base to enhance or change its properties. These additives can serve various purposes, such as improving texture, adding color, enhancing fragrance, or offering specific skin benefits.
In the context of melt and pour soap making, additives are typically added after the soap base has been melted and before the mixture is poured into molds. Additives can be natural, such as oils, herbs, and clays, or synthetic, like fragrances and colorants.

2. What You Can Add to Melt and Pour Soap
Here’s a rundown of some of the most popular and safe additives you can use in your melt and pour soap creations:
Moisturizing Additives
These ingredients are perfect for making your soap more hydrating and skin-friendly, ideal for dry skin or those who prefer a gentler, nourishing soap.
-
Essential Oils: Add a few drops of essential oils like lavender, peppermint, or tea tree oil for fragrance and potential skin benefits. Remember that a little goes a long way!
-
Carrier Oils: Oils like jojoba, argan, olive, and coconut oil can enhance moisturizing properties. Add around 1-2 teaspoons per pound of soap base to avoid making the soap too greasy.
-
Shea Butter: A popular choice for added moisture and skin benefits, shea butter can be melted and added to your soap base. Aim for 1 tablespoon per pound of soap base.
-
Aloe Vera Gel: Aloe vera is known for its soothing and moisturizing properties. You can add 1-2 teaspoons per pound of soap base.
Colorants and Dyes
Colorants are one of the easiest ways to give your soap a unique look. Here are some safe options:
-
Mica Powder: Mica is a mineral-based pigment that adds vibrant, shimmering colors to your soap. It’s available in a variety of shades and can be mixed directly into the melted soap.
-
Liquid Soap Dyes: These are designed for soap-making and can give you rich, even colors. They are typically more concentrated, so be cautious with the amount you use.
-
Natural Colorants: For a more natural approach, consider using turmeric, spirulina powder, or activated charcoal for earthy tones. Just be sure to check how they react with your soap base.
Exfoliants
Exfoliants help to remove dead skin cells, leaving the skin smooth and refreshed. These additives can give your soap a more luxurious, spa-like feel.
-
Oats: Ground oats or colloidal oats are great for gentle exfoliation and soothing the skin. Add around 1-2 tablespoons per pound of soap base.
-
Coffee Grounds: If you want a stronger exfoliant, coffee grounds can be a great option, especially in scrubs or men’s soaps. Use sparingly, as they can be a bit coarse—1 tablespoon per pound of soap.
-
Sea Salt or Epsom Salt: Salt provides an excellent natural exfoliant and helps to create a more hard soap bar. Add around 1 tablespoon per pound.
Fragrances
Fragrance oils and essential oils are key ingredients to adding delightful scents to your soap. While both types can be used, there are some important distinctions.
-
Essential Oils: These are natural oils derived from plants. They provide not only fragrance but potential therapeutic benefits. Common essential oils for soap include lavender, eucalyptus, and citrus oils. Add 0.5-1 oz per pound of soap base.
-
Fragrance Oils: These oils are synthetic and often more affordable than essential oils. Be sure to check that your fragrance oil is specifically formulated for soap making, as some may cause the soap to discolor or separate.

Clays and Mud
Clays can be added to melt and pour soap for a more luxurious feel, and they can also offer skin benefits.
-
Kaolin Clay: A gentle clay that helps to smooth the skin and can act as a thickener. 1-2 teaspoons per pound is a good starting point.
-
Bentonite Clay: Adds a silky texture to soap and is known for its detoxifying properties. Start with 1 teaspoon per pound.
-
French Green Clay: Adds a natural green color and can be used for oil-absorbing soaps. It’s best to use around 1 teaspoon per pound.
3. What You Cannot Add to Melt and Pour Soap
While there are many ingredients you can safely add, there are also some additives that should be avoided, as they can compromise the quality or safety of your soap.
Unapproved Colorants or Dyes
-
Food Coloring: While food coloring is safe for consumption, it’s not recommended for soap. Food dye can stain the skin or the soap mold, and it may not be as vibrant or long-lasting in soap.
-
Non-Soap-Safe Dyes: Always use soap-safe dyes and pigments, as other colorants may not blend well with soap or may cause reactions when exposed to the lye.
Liquid Additives (In Excess)
While it’s tempting to add extra oils or liquids like milk or honey, adding too much of these can cause the soap to become too soft or result in separation. Stick to the recommended amount and remember that some ingredients can cause melt and pour soap to seize up or become too greasy.
Strong Scrubbers Like Pumice or Ground Nutshells
Certain harsh scrubbers like pumice or ground nuts can be too abrasive for the skin and may disrupt the texture of the soap. If you’re looking for exfoliation, opt for gentler options like oats, salt, or coffee grounds.
Water
Water should never be added directly to melt and pour soap bases. Water will dilute the soap and could cause it to seize or lose its integrity, leading to a soft bar that’s difficult to mold and use.
4. Tips for Using Additives in Melt and Pour Soap
-
Incorporate Additives Slowly: Always start by adding small amounts of each additive. This way, you can see how it affects the texture and appearance of your soap.
-
Mix Thoroughly: Be sure to mix additives in well to avoid clumps and ensure even distribution throughout the soap.
-
Test Before Making Large Batches: If you’re trying a new additive or combination, always test it in a small batch first to ensure it behaves as you expect.
-
Avoid Overloading with Additives: Too many additives can cause your soap to become overly greasy, brittle, or difficult to unmold.
