The melt-and pour soap base provides the perfect canvas for soap makers to swirl, stamp, scent, and customize creatively without any lye or chemical processing. Its gentle, glycerin-rich formula makes it an excellent base into which a wide variety of additives can be incorporated. From nourishing oils and butters to exfoliating oats and seeds to vivid colors and essential oil blends, the possibilities are endless. Experimenting with unique inclusions like clays allows for delightful surprises and inspiration for one’s next masterfully formulated soap recipe.

What is Melt and Pour Soap?

Melt and pour soap base starts with vegetable oils like coconut, palm, olive, and palm kernel that undergo saponification, a chemical process of combining oils with lye to produce soap. Additional ingredients like glycerin, sorbitol, and sucrose may be added to the processed soap base to improve lather, hardness, and moisturization.

Ingredients and Manufacturing Process

The oils, lye, and any extras are combined in specific ratios, heated, mixed, and then poured into molds to set. Once hardened, it’s cut into blocks and packaged as a melt-and-pour soap base.

Benefits of Using a Melt and Pour Soap Base

This premade, molded glycerin soap base eliminates the hassles of saponification. With a melt-and-pour base, hobbyists can simply melt, color, scent, and mold beautiful soap bars right at home without dealing with lye or a difficult curing process. It’s a versatile DIY soapmaking starter base.

Adding Ingredients to Melt and Pouring Soap

Getting creative with melting and pouring soap is part of the fun. There’s an abundance of additives that can be incorporated to customize the soap’s look, smell, and feel.

Common Additives

Enhancing a simple soap base is limited only by one’s imagination. Some of the most popular additives include:

Essential Oils

A few drops of essential oils not only provide a lovely scent but can also provide skin benefits. Lavender and tea tree oils soothe the skin. Citrus oils energize. The options are endless.

Botanicals and Dried Flowers

Dried herbs, flowers, and botanical ingredients like oatmeal or coffee grounds add natural beauty, exfoliation, and visual intrigue. Popular botanical additives include lavender buds, rose petals, and calendula flowers.

Coloring Agents

Vibrant micas and oxides transform plain soap into a visually stunning work of art with mesmerizing colors and designs.

Exfoliants

Ground oatmeal, sea salt, coffee grounds, and more scratch away dead skin cells to leave skin smooth and soft.

Guidelines for Additives

When customizing, keep additives at 2 tablespoons or less per pound of soap base. Mix the powders carefully to avoid clumps. Spritz dried botanicals with rubbing alcohol for best adhesion. Use caution with liquids that may seize or accelerate trace.

Experimenting with Clay in Melt and Pour Soap

Clay might seem like an unlikely soap additive, but it offers some wonderful benefits that make it worth testing.

Benefits of Clay

The cleansing and absorptive properties of clay can be an asset in soap-making. Different clays also provide unique qualities.

Bentonite Clay

With excellent absorption abilities, bentonite clay makes a great facial soap, sucking impurities from pores. It also thickens soap to make an indulgent, creamy lather.

Rhassoul Clay

Rhassoul clay’s impressive cleaning capabilities and ability to condition skin and improve clarity make it ideal for nurturing yet detoxifying skin.

Kaolin Clay

Kaolin clay gently exfoliates to scrub away dead skin cells, unclog pores, and smooth skin texture. Its light white color also makes vibrant soap colors pop.

Testing Different Clay Amounts

Adding too much clay can make soap brittle or dull. Testing small batches with different percentages yields ideal formulas.

5% Clay

A 5% clay-to-soap base ratio adds mild exfoliation without significantly muting color.

10% Clay

Increasing clay content to 10% boosts exfoliation, absorption, and skin benefits while maintaining decent moldability.

15% Clay

Further bumping clay up to 15% risks more fragility but maximizes clay properties.

Clay Incorporation Methods

Clays can be incorporated into melt and pour soap in two ways.

Mixing In

Stirring clay powder right into melted soap is simple but can leave speckles.

Clay Embeds

For a seamless look, mold clay separately, then embed bars into the melted base.

Results and Recommendations

Testing different clay types, quantities, and preparation methods offers helpful insights for best practices.

Observations from Experiments

By evaluating the test batches, some clear winners and lessons learned emerged.

Appearance

Smooth clay embed layers retain vivid soap color vibrancy better than speckled in-soap mixing.

Lather and Texture

10% rhassoul clay yields a rich, creamy texture later, while higher rates get draggy and dry.

Scent Retention

Essential oils infuse nicely into kaolin or bentonite clay embeds, holding fragrance better than mixing into the base.

Ideal Clay Usage Rate

For balancing visual appeal with physical properties, 10% clay proves optimal. Higher rates increase the chances of seizing and cracking.

Best Practices for Adding Clay

Clay embed layers help reinforce bars for perfect release from molds. Spritzing layers with rubbing alcohol prevents air bubble pits. Light misting of essential oils into clay before embedding boosts the lingering aroma.

Experimenting with clay in melt and pour soap unlocks an array of visual and skin care benefits from this versatile additive. Carefully testing variables offers helpful guidance for maximum creative customization success without compromising soap quality. Further exploring clays and additives keeps soap making exciting!
