Question 1

What does Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as an oil-gelling agent, film-former, and texture builder in color cosmetics, balms, sticks, and anhydrous formulas. It helps thicken oils, improve payoff, add structure, and support longer wear.

Question 2

Is Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer clean?

Accepted Answer

From a clean-beauty perspective, this ingredient has friction because it is a synthetic polymer used for film formation and texture, not because it is a common sensitizer. It is generally low-irritation in finished formulas, but some standards scrutinize it under synthetic polymer or microplastic-related policies.

Question 3

Is Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer sustainable?

Accepted Answer

This material is partly based on fatty-acid-derived building blocks, but it is chemically polymerized and not considered readily biodegradable. Its main sustainability concern is environmental persistence rather than high acute irritation potential.

Question 4

Is Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer COSMOS-approved?

Accepted Answer

This ingredient is not typically permitted under COSMOS organic or natural standards because it is a synthetic film-forming polymer outside the standard’s allowed ingredient set. Its Green Chemistry profile is mixed, with some bio-based inputs but limited biodegradability and a more persistent polymeric structure.

Question 5

How does Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer work chemically?

Accepted Answer

This compound is an amide-linked synthetic polymer made from diamine and long-chain fatty building blocks, giving it strong oil compatibility and network-forming behavior in anhydrous systems. It is commonly used at low single-digit to higher structuring levels depending on format, especially in sticks and hot-pour systems, and it is generally stable across typical anhydrous cosmetic processing conditions.
