Tips for Making Perfect Rainbow Soap
- Use micas or pigments safe for use in soap colorant formulations to ensure bright radiant colors that will remain true over time and won't bleed together from one layer to another.
- Timers should be used to help prevent the pouring of layers when the soap is too hot-wait until it cools slightly before attempting to pour to avoid melting the one below it.
- Spritz rubbing alcohol in between layers to get those bubbles popping and create a smooth concave between layers.
- Selecting the right essential oils that are skin-appropriate and safe from irritation adds skin benefits and fragrance to your soap.
