Step-by-Step Production Process
- Preparation and Safety (20-30 minutes): Wear PPE (gloves, goggles). Sanitize large pots, stirrers, and containers. Measure oils and KOH accurately.
- Saponify Oils (1-2 hours): Heat oils (coconut, olive) to 50°C in a large stainless steel pot. Dissolve KOH in distilled water (carefully, exothermic). Add to oils and cook on low heat until trace and paste forms.
- Dilute Paste (30-45 minutes): Slowly add hot distilled water to soap paste while stirring to create a smooth liquid. Continue heating and mixing until fully diluted (clear/translucent).
- Add Additives (15 minutes): Once cooled to 40°C, stir in glycerin, fragrance, blue colorant, and preservative. Adjust thickness with salt solution if needed.
- Bottling (20-30 minutes): Filter if lumpy, then pour into sanitized pump bottles (e.g., 500ml each). Cap and label.
- Cooling and Neutralization (1-2 hours): Let cool completely. Test pH (8-10 for mildness). Neutralize excess lye if necessary with citric acid.
- Quality Check (10 minutes): Shake-test for lather, check color stability, and scent. Shelf life: 6-12 months.
Total time: 3-5 hours active + cooling. Yields ~60 500ml bottles. Ideal for hand, body, or surface cleaning.
