If your soap isn't getting hard, it's likely due to high moisture content or incorrect soap formula proportions. Ensure you're following your soap recipe accurately, particularly the ratio of oils to lye. High humidity can also affect the curing process. To troubleshoot, store your soap in a cool, dry place and consider using a dehumidifier. If you're making cold process soap, extending the curing time may help. For melt and pour soaps, reducing additional liquid ingredients could lead to a harder final product.
