FAQ

How long does cold process soap need to cure?

Most cold process soaps need a minimum of 4 weeks to cure, though 6-8 weeks is recommended for a harder and milder bar.

Can I use hot process soap immediately?

Hot process soap can technically be used immediately after it has cooled, but curing for 1-2 weeks improves lather quality and hardness.
