This is a tried and true recipe that I've made several times. Others have tried it with excellent results. Be sure to keep the bar high and dry between uses by using a soap-saver-type soap dish. Tweak to your heart's delight! (Like, do I even need to say that?! ) ZANY’S NO SLIME OLIVE OIL CASTILE Ingredients: Olive oil, water, sea salt, sodium bicarbonate. 1) MAKE FAUX SEAWATER - Use for water portion of the lye solution. 1 quart warm water 1 Tablespoon sea salt 1 Tablespoon sodium bicarbonate (baking soda) I make up a quart at a time and store it in the fridge until I need it. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2) MAKE LYE SOLUTION - Mix and allow to cool to 35°C - 40°C (100°F - 110°F). 1.7:1 Water to Lye Ratio (Note decimal and colon) 0% Super Fat/Lye Discount Notes: I’ve tried 2:1 and 1.5:1. 1.5:1 gets almost too hard and 1:2 is okay but a bit slimey, so, for me, 1.7:1 is the ideal. Olive oil is high in unsaponifiables; so 0% SF works best to reduce slippery slime. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Prepare lye solution and set it in the sink to cool. Weigh olive oil into soap pot. Warm to 35°C - 40°C (100°F - 110°F). Combine when lye and oils are within -12°C (10°F) of each other. SB on and off to emulsion stage (5 - 25 minutes, depending on grade of olive oil.) Slowly pour into mold. Tap to remove bubbles. Spritz lightly with alcohol. Cover with plastic wrap. Insulate. Leave soap undisturbed for 12-24 hours. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ UNMOLD in 12-24 hours CUT Day 2 CURE Ready to ship in 2 weeks. 6 weeks is best. The longer the cure the better the soap. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Unscented, this soap is suitable for babies, sensitive skin, and for cancer patients undergoing radiation. Add 5% castor oil and 10% coconut oil for bubbles and an even milder soap. If adding fragrance, add 0.85 oz. FO or 0.5% EO /PPO (Per 500 grams) to the castor oil an hour or so ahead of time (or overnight) and a teaspoon PPO of dry ingredient of choice -- corn starch, oat flour, arrowroot powder, White Kaolin Clay, etc. -- to help “stick” the fragrance. VARIATIONS: Infuse Calendula Petals (yellow) or Bay Leaves (green) in oil ahead of time. Strain. Use up to 40% in the batch to add mildness and color.
