Solubility & Compatibility

Every cosmetic formula is a balance of water-soluble and oil-soluble components, held together by an emulsification system. Getting this balance wrong leads to phase separation, poor texture, reduced efficacy, and wasted production batches. COSMIC's Solubility and Compatibility engine automates the complex calculations that underpin a stable formulation.

The system automatically assigns each ingredient to the correct manufacturing phase: Phase A (water and water-soluble components, heated to 70-80 degrees Celsius), Phase B (oils, silicones, waxes, and emulsifiers, heated separately), Phase C (heat-sensitive ingredients added during cooling), and Phase D (colorants and pigments). These assignments are based on each ingredient's solubility profile, melting point, and thermal stability.

For emulsion systems, the platform calculates the required HLB (Hydrophilic-Lipophilic Balance) for the oil phase blend, selects compatible emulsifiers, and verifies the surfactant-to-oil ratio. It recommends O/W (oil-in-water) or W/O (water-in-oil) systems based on the product type and performance requirements, and automatically detects when the emulsifier system is insufficient or mismatched.

Incompatibility detection runs in real time. When two ingredients in the formula are known to conflict — for example, cationic polymers with anionic surfactants, or certain preservatives with nonionic emulsifiers — the platform flags the issue immediately and suggests alternatives. This prevents formulation failures that would only become apparent after costly stability testing.
