Lye-Free Liquid Glycerin Soap
A gentle, moisturizing liquid soap made from glycerin melt-and-pour base — no lye required, perfect for hands, body, or face.
Traditional liquid soap making requires lye (sodium or potassium hydroxide) and careful safety precautions. This glycerin-based method bypasses all of that — the saponification has already been done in the commercial glycerin soap base, so you are simply melting, diluting, and customizing without any caustic chemicals involved.
Glycerin is a humectant that attracts moisture to the skin — glycerin-based soaps are inherently more moisturizing than most commercial soaps, which often strip glycerin out during manufacturing. The carrier oil adds an additional conditioning layer, and vegetable glycerin boosts the soap's natural moisturizing properties.
The result is a gentle, non-drying liquid soap appropriate for hands, body, or face. Essential oils provide scent and any additional properties you want — lavender for calming, tea tree for antimicrobial action, peppermint for refreshing, or any combination you prefer. The soap may separate slightly over time — a gentle shake before use is all that's needed.
Ingredients
- 1/2 lb glycerin melt-and-pour soap base

- Optional: 1 tsp natural thickener (xanthan gum or guar gum)
How to Use
- 1Cut glycerin soap base into small chunks and melt in a double boiler or microwave in 30-second bursts, stirring between each.
- 2While stirring constantly, slowly mix in distilled water — the mixture will become liquid soap.
- 3Stir in carrier oil and vegetable glycerin.
- 4Allow to cool, then add essential oils.
