Tips & Tricks

Clean Organic Standard

  • Zero Seed Oils: Avoid inflammatory, high-PUFA oils (canola, sunflower, soybean, safflower, corn).
  • Nourishing Plant Oils: Formulate with organic olive, coconut, avocado, castor, and shea butter.
  • Zero Synthetic Fragrance: Scent exclusively with 100% pure organic steam-distilled essential oils.
  • Natural Mineral Clays: Color with French clays, activated charcoal, and organic plant powders.

Lye Safety

  • Always add lye to water — never water to lye.
  • Wear gloves, goggles, and long sleeves every time.
  • Work in a well-ventilated area — fumes are caustic.
  • Use stainless steel or heat-safe plastic. No aluminum!
  • Keep white vinegar nearby to neutralize spills.
  • Keep children and pets out of the workspace.

Temperature Guidelines

  • Let lye water cool to 90–100°F before combining.
  • Melt oils to 90–100°F for a good match.
  • Lower temps (70–80°F) give a longer working time for intricate swirls.
  • Higher temps speed trace — great for rustic pours, risky for designs.
  • Use a digital thermometer — guessing causes seized batches.

Understanding Trace

  • Thin trace: Like melted ice cream. Best for swirls and intricate work.
  • Light trace: Like thin cake batter. Good all-purpose pour point.
  • Medium trace: Like pudding. Best for layers and textured tops.
  • Heavy trace: Like mashed potatoes. Pour immediately — no swirling possible.
  • Stick blend in short bursts and hand-stir between to control trace speed.

Essential Oil Tips

  • Use 2–3% of total oil weight as a starting point for EO amounts.
  • Citrus EOs (lemon, orange) fade quickly — anchor with a fixative like cedarwood.
  • Some EOs (clove, cinnamon) accelerate trace rapidly — have your mold ready.
  • Add EOs at light trace, not before — heat can volatilize them.
  • Blend EOs ahead of time so they’re ready to pour without delay.

Natural Colorants

  • Disperse colorants in a small amount of oil before adding to batter.
  • Pink Kaolin Clay (Rose Clay): Muted blush pink, silky, and skin-loving. Very soap-stable.
  • Spirulina: Vivid green that may fade to earthy tones over time.
  • Turmeric: Bright yellow, antioxidant. May morph to orange.
  • Activated charcoal: True black, great for detox bars.
  • Indigo powder: Rich blue, very stable in cold process.
  • Always test colorants in a small batch first — morphing is common!

Mold & Unmolding

  • A standard 4–10 lb loaf mold (44 oz oil) yields ≈12–14 bars.
  • Insulate with a towel or wooden lid for gel phase — gives vibrant, translucent color.
  • Skip gel by placing in the fridge/freezer for 24h — pastel, matte finish.
  • Wait 24–48 hours before unmolding. If it’s soft, wait longer.
  • Wear gloves when cutting — fresh soap is still caustic until fully saponified.

Curing

  • Cold process soap needs a minimum 4–6 weeks cure.
  • Curing evaporates water, making a harder, longer-lasting bar.
  • Place bars on a wire rack with airflow on all sides.
  • Turn bars weekly for even drying.
  • Store away from direct sunlight to prevent fading.
  • Soap continues to improve for up to 6 months!

Troubleshooting

  • Soda ash: White powder on top. Harmless — steam lightly or plane off.
  • Seizing: Batter thickens instantly. Usually from EOs or high temps. Pour immediately into mold.
  • Ricing: Lumpy, curdled batter. Stick blend hard to re-emulsify.
  • Dreaded orange spots (DOS): Rancidity from old oils. Use fresh oils and keep water content low.
  • Soft after 48h: High water or low hard oils. Extended cure time will fix it.
  • Zap test: Touch a tiny piece to your tongue — if it “zaps” (tingles), it needs more cure.
