Microcrystalline Wax/Cera Microcristallina ●
TL;DR. It acts as a structuring and viscosity-building agent, helping balms, sticks, ointments, and color cosmetics hold shape. It also improves slip, water resistance, and occlusive feel on skin or lips.
What does Microcrystalline Wax/Cera Microcristallina do in a cosmetic formula?
It acts as a structuring and viscosity-building agent, helping balms, sticks, ointments, and color cosmetics hold shape. It also improves slip, water resistance, and occlusive feel on skin or lips.
Is Microcrystalline Wax/Cera Microcristallina clean?
Clean-beauty frameworks often flag it because it is petroleum-derived and depends on high refining quality to control aromatic mineral-oil residues. It is generally low-irritation, but its sourcing and impurity profile create clean-standard friction.
Is Microcrystalline Wax/Cera Microcristallina sustainable?
This material comes from non-renewable petroleum refining. Its saturated hydrocarbon structure is not readily biodegradable, so it has a weaker environmental profile than renewable plant-derived structuring agents.
Is Microcrystalline Wax/Cera Microcristallina COSMOS-approved?
It is not permitted under COSMOS natural or organic standards because it is a petrochemical-derived hydrocarbon blend rather than an allowed natural-origin material. From a Green Chemistry view, it scores poorly on renewable feedstock and biodegradability, despite being chemically stable and typically low-reactivity in formulas.
How does Microcrystalline Wax/Cera Microcristallina work chemically?
This material is a semi-solid mixture of high-molecular-weight, mostly saturated branched and cyclic hydrocarbons, which gives it a higher melting range and stronger oil-binding capacity than many softer hydrocarbon blends. It is commonly used in anhydrous systems and emulsions at low single-digit to higher structuring levels, with stability driven more by heat and oil compatibility than by pH.
