Incompatibility between biopolymers and fatty substances leads to phase separation or poor texture. Achieving structural integrity in sustainable cosmetic bases ensures product shelf life and sensory performance.

Excessive mass in recycled thermoplastic components limits fuel efficiency and material portability. Reducing density through gas-assisted bioresin integration overcomes the weight penalty of standard recycled polypropylene.

Conventional cosmetic formulations rely on synthetic polymers that do not break down, leading to long-term ecological accumulation. Replacing these with biodegradable alternatives prevents microplastic pollution and bioaccumulation in aquatic ecosystems.
