Question 1

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

Accepted Answer

This ingredient is a lipophilic structurant, thickener, and occlusive film-former used to give balms, sticks, creams, and color cosmetics firmness, slip, and water resistance.

Question 2

Is Cera Microcristallina/Microcrystalline Wax/Cire Microcrystalline clean?

Accepted Answer

From a clean-beauty perspective, it is usually flagged for petrochemical origin rather than for high irritation potential. It is generally well tolerated on skin, but it has clean-standard friction because it is non-renewable and may be excluded by natural-certification programs.

Question 3

Is Cera Microcristallina/Microcrystalline Wax/Cire Microcrystalline sustainable?

Accepted Answer

This material is sourced from petroleum refining, so its feedstock is non-renewable. It is not considered readily biodegradable and can persist in the environment compared with many plant-derived lipids.

Question 4

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

Accepted Answer

It is generally not permitted under COSMOS-natural or COSMOS-organic because it is a petrochemical-derived material. Its Green Chemistry fit is weak due to fossil sourcing and limited biodegradability, even though it is chemically stable and typically requires no reactive processing in final formulas.

Question 5

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

Accepted Answer

This material is a complex mixture of high-molecular-weight branched and cyclic saturated hydrocarbons, often in the approximate C30 to C60 range. It commonly appears at about 1 to 15% in sticks, balms, and anhydrous products, with melting behavior often around 60 to 90°C and strong stability across normal cosmetic pH conditions.
