Question 1

What does Ipdi/Di-C12-13 Alkyl Tartrate/Bis-Hydroxyethoxypropyl Dimethicone Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is primarily a film-former and water-resistance agent for long-wear color cosmetics, sunscreens, and skin products. It helps bind pigments and powders, improve slip, and leave a flexible, conditioning film.

Question 2

Is Ipdi/Di-C12-13 Alkyl Tartrate/Bis-Hydroxyethoxypropyl Dimethicone Copolymer clean?

Accepted Answer

From a clean-beauty perspective, this ingredient has friction because it is a highly synthetic polymer with siloxane and urethane chemistry. Finished-product irritation is generally expected to be low, but its synthetic origin and persistence profile place it outside many stricter clean frameworks.

Question 3

Is Ipdi/Di-C12-13 Alkyl Tartrate/Bis-Hydroxyethoxypropyl Dimethicone Copolymer sustainable?

Accepted Answer

This material is synthetic and is typically made from petrochemical and silicon-derived inputs rather than renewable feedstocks. It is not considered readily biodegradable, so its environmental profile is less aligned with low-persistence formulation goals.

Question 4

Is Ipdi/Di-C12-13 Alkyl Tartrate/Bis-Hydroxyethoxypropyl Dimethicone Copolymer COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS natural or organic standards. From a Green Chemistry view, it has limited alignment because it relies on synthetic polymer chemistry, nonrenewable inputs, and poor biodegradability, even though it can improve product durability at low use levels.

Question 5

How does Ipdi/Di-C12-13 Alkyl Tartrate/Bis-Hydroxyethoxypropyl Dimethicone Copolymer work chemically?

Accepted Answer

The molecule is a crosslinked-style copolymer built from flexible siloxane segments, urethane linkages, long-chain ester groups, and polyether functionality, giving both film formation and cosmetic slip. It is typically used as a performance polymer in anhydrous or emulsion systems, with compatibility depending on oil phase, elastomer, pigment, and volatile carrier selection.
