Professional Soap Making & Regulatory Compliance

Saponification Science

Saponification converts triglycerides (oils) and sodium hydroxide (lye) into soap and glycerin. Understanding SAP values and fatty acid profiles helps predict soap characteristics and optimize formulations for specific skin types and use cases.

INCI Compliance

INCI (International Nomenclature of Cosmetic Ingredients) provides standardized names for cosmetic ingredients. Our calculator generates compliant labels for USA (FDA), EU (ECHA), and Canada (Health Canada) regulations with proper concentration disclosures.

Additive Integration

Cold process additives must be integrated at specific trace stages. Clays and colorants at light trace, fragrances at medium trace, and delicate botanicals at heavy trace. This timing prevents acceleration and ensures even distribution.

Professional Safety & Regulatory Guidelines

Laboratory Safety

  • OSHA-compliant safety equipment (goggles, gloves, apron)
