What the AI looks for in Soap Making Bases & Melts
- Detergent content
- Prefer bases labelled SLS/SLES-free if skin sensitivity matters. Some cheaper bases rely on added surfactants that can be harsher on skin.
- Sweat resistance
- Look for bases marketed as low-sweat or suspension-free formulas suited to your humidity. Glycerin-rich bases pull moisture from the air and bead up, so finished bars need wrapping.
- Clear vs opaque
- Use clear for embeds and bright colors, and white or opaque for pastel and creamy looks. The base color sets what your colorants will look like and whether embeds show.
- Gentle melting
- Melt in short bursts or a double boiler and never let it boil. Overheated base turns rubbery, discolors and loses moisture.
- Suspension formulas
- Choose a suspending base if you will add botanicals, exfoliants or glitter. Regular base lets additives sink to the bottom of the mold.
Brands that matter
- Stephenson: Crystal line is widely used, consistent and SLS-free.
- Crafter's Choice: Many specialty and detergent-free bases.
- SFIC: Established melt-and-pour base manufacturer.
What to avoid
- Unbranded bases with no ingredient list
- Re-melting the same base many times, which dries it out
- Food coloring or candle dye in melt-and-pour
Questions
Can I call melt-and-pour soap 'handmade natural soap'?
It is already saponified by the manufacturer. You are customizing it, so check the base's ingredient list before making natural claims.
