Question 1

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

Accepted Answer

This ingredient is an occlusive wax and structuring agent that thickens balms, sticks, salves, and creams. It adds firmness, slip control, water resistance, and a protective film on skin or hair.

Question 2

Is Cera Microcristallina/Microcrystalline Wax/Cire Icrocristalline clean?

Accepted Answer

From a clean beauty perspective, this ingredient is usually flagged because it is petroleum-derived, even though the refined cosmetic grade is generally low-reactivity and well tolerated. Standards and retailers may require high refining quality and limits on polycyclic aromatic impurities.

Question 3

Is Cera Microcristallina/Microcrystalline Wax/Cire Icrocristalline sustainable?

Accepted Answer

This material comes from fossil refining, so it is not a renewable feedstock. It is not readily biodegradable and can persist in the environment compared with plant-based waxes.

Question 4

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

Accepted Answer

It is not permitted in COSMOS-natural or COSMOS-organic formulas because it is a petrochemical hydrocarbon wax. Its Green Chemistry fit is weak due to fossil sourcing and limited biodegradability, although it is chemically stable and does not require complex reactive chemistry in use.

Question 5

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

Accepted Answer

The molecule profile is a mixture of high-molecular-weight saturated hydrocarbons, with branched and cyclic structures that create a flexible, oil-binding wax network. Typical use levels range from about 1 to 20% depending on product format, and it is broadly pH-inert, oxidation-resistant, and most useful in anhydrous or emulsion systems that need body and film formation.
