Incompatibility between silicone and hydrocarbon phases leads to poor adhesion and structural failure of the cosmetic layer. Resolving this ensures long-wear durability and uniform pigment distribution.

Surface wear and moisture exposure cause premature degradation of cosmetic layers. Improving adhesion and resistance to mechanical transfer ensures long-term wearability.

Incompatibility between ethylcellulose and diverse oil phases leads to phase separation and uneven color distribution. Stabilizing these interfaces prevents pigment flocculation and ensures long-term formulation homogeneity.
