Question 1

What does Microcrystalline Wax/Cera Microcristallina/Cire Microcristalline do in a cosmetic formula?

Accepted Answer

This ingredient is used as an oil-phase structurant, thickener, binder, and occlusive film former in sticks, balms, ointments, and color cosmetics. It improves hardness, payoff, gloss, and water resistance.

Question 2

Is Microcrystalline Wax/Cera Microcristallina/Cire Microcristalline clean?

Accepted Answer

This material is generally low-irritation when highly refined, but it has clean-standard friction because it is petroleum-derived. Some frameworks flag it for refinement quality and potential trace PAH impurities, which are controlled by cosmetic-grade specifications.

Question 3

Is Microcrystalline Wax/Cera Microcristallina/Cire Microcristalline sustainable?

Accepted Answer

This ingredient comes from fossil feedstocks rather than renewable plant or mineral sources. It is highly stable and not readily biodegradable, so its environmental profile is weaker than many bio-based structuring agents.

Question 4

Is Microcrystalline Wax/Cera Microcristallina/Cire Microcristalline COSMOS-approved?

Accepted Answer

This ingredient is not permitted in COSMOS-natural or COSMOS-organic products because it is a petrochemical-derived material. Its Green Chemistry fit is limited by nonrenewable sourcing and poor biodegradability, even though it is chemically inert and low-reactivity in formulas.

Question 5

How does Microcrystalline Wax/Cera Microcristallina/Cire Microcristalline work chemically?

Accepted Answer

This material is a complex solid blend of mostly branched and cyclic saturated hydrocarbons, with a fine crystalline structure that gives high viscosity and strong oil-binding behavior. It is pH-independent, used in the heated oil phase, typically melts around 60 to 90°C, and can appear from low single digits in emulsions to much higher levels in sticks and balms.
