Microcrystalline Wax/Cera Microcristallina/Cire Microcristallina ●
TL;DR. This material is an oil-phase structurant and thickener used to harden sticks, stabilize balms, raise melting point, and add water resistance and gloss. It also helps suspend pigments and reduce oil bleed in anhydrous formulas.
What does Microcrystalline Wax/Cera Microcristallina/Cire Microcristallina do in a cosmetic formula?
This material is an oil-phase structurant and thickener used to harden sticks, stabilize balms, raise melting point, and add water resistance and gloss. It also helps suspend pigments and reduce oil bleed in anhydrous formulas.
Is Microcrystalline Wax/Cera Microcristallina/Cire Microcristallina clean?
It is generally low in skin irritation when highly refined, but many clean standards scrutinize it because it is petroleum-derived and can carry purity expectations around residual aromatic fractions. Brands positioned around natural-origin materials often exclude it even though cosmetic grades are tightly refined.
Is Microcrystalline Wax/Cera Microcristallina/Cire Microcristallina sustainable?
It comes from petroleum refining, so it is non-renewable and has weaker alignment with bio-based sourcing goals. It is not readily biodegradable and is expected to persist longer than many plant-derived lipids.
Is Microcrystalline Wax/Cera Microcristallina/Cire Microcristallina COSMOS-approved?
It is not permitted under COSMOS natural or organic standards because it is fossil-derived rather than an allowed natural-origin or approved synthetic input. From a Green Chemistry lens, the main gaps are non-renewable feedstock and limited biodegradability, though its functional efficiency can reduce the need for multiple separate structuring agents.
How does Microcrystalline Wax/Cera Microcristallina/Cire Microcristallina work chemically?
This material is a complex mixture of high-molecular-weight, mostly saturated branched and cyclic hydrocarbons, typically with a melting range around 60 to 90°C and strong oil-binding capacity. Typical use is about 1 to 10% in creams and balms and 5 to 25% in sticks, with stability driven by heat processing above its melt range, compatibility with oils and esters, and strong resistance to oxidation.
