Frequently asked questions

Practical answers before you start.

General guidance lives here. Formula-specific details stay with the product they apply to.

What is melt and pour soap base?+

It is a premade soap base that has already completed saponification. Cut it, melt it gently, add compatible color or fragrance, and pour it into a mold. Once it is fully cool and hard, it is ready to use without a curing period.

Can I add fragrance or color?+

Yes. A common working range for fragrance in melt and pour soap is 2–3% of the base weight, but never exceed the lower of the soap base’s published maximum and the fragrance supplier’s current IFRA Category 9 limit. Use only skin-safe fragrance intended for rinse-off soap. For color, use a melt-and-pour-compatible colorant, follow that colorant supplier’s rate, and add it gradually until the desired shade is reached. Different dyes, micas, pigments, and clear or white bases behave differently, so test a small batch first.

What are the ingredients in melt and pour soap base?+

Each formula is different. Open the individual product page for the exact base and review its Product Information section for the complete, product-specific ingredient list.

Where can I find the Safety Data Sheet (SDS)?+

The current bilingual SDS for each formula is available from that soap base’s individual product page and from the Safety Data Sheet library. Always use the document linked to the exact product you purchased.

Where can I buy Arts & Crafts soap base?+

You can buy directly from this website, from Amazon, or from another approved marketplace. Each product page shows the available purchase buttons; use those links to identify Arts & Crafts and its authorized marketplace options.

I have questions about shipping or returns.+

Shipping and return terms can vary by order channel, destination, and order size. Review our Shipping & returns page for the applicable guidance.

Why does melt and pour soap sometimes sweat?+

The glycerin in melt and pour soap can attract moisture from humid air, creating droplets known as glycerin dew. Let finished bars cool completely, then wrap them tightly or use airtight packaging and store them in a cool, dry place.

Can I adjust the pH of the soap base?+

Do not try to adjust the pH unless the specific formula documentation expressly permits it. Changing pH can destabilize a prepared soap base. Check the product page for its verified pH range and technical guidance.

Are fragrance oils and essential oils interchangeable?+

No. Both must be suitable for skin contact and rinse-off soap, but they can have different safe-use limits and performance. Some essential oils can affect clarity or stability, so follow the supplier’s documentation and test a small batch before producing a larger run.
