Question 1

What does Peg-7 Amodimethicone do in a cosmetic formula?

Accepted Answer

This ingredient is primarily a hair-conditioning and deposition agent that forms a thin, lubricating film for slip, wet combing, frizz control, and shine. Its polyether modification helps it disperse in water-based formulas better than many hydrophobic conditioning polymers.

Question 2

Is Peg-7 Amodimethicone clean?

Accepted Answer

This ingredient is a synthetic conditioning polymer, so it often has friction in clean frameworks that limit organosilicon polymers and ethoxylated materials. Skin irritation is generally low in rinse-off hair care, but specifications should control residual ethoxylation byproducts such as 1,4-dioxane.

Question 3

Is Peg-7 Amodimethicone sustainable?

Accepted Answer

This material is made from nonrenewable feedstocks and is not readily biodegradable. In wastewater, removal is expected mainly through adsorption to sludge rather than rapid mineralization, which gives it a weaker environmental profile than readily biodegradable conditioners.

Question 4

Is Peg-7 Amodimethicone COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic organosilicon polymer with ethoxylated segments. Its Green Chemistry fit is limited by nonrenewable sourcing, persistence, and ethoxylation, despite effective performance at low use levels.

Question 5

How does Peg-7 Amodimethicone work chemically?

Accepted Answer

The molecule has a hydrophobic polysiloxane backbone, pendant amino groups that bind to negatively charged hair, and short polyether chains that improve water dispersibility. Typical use levels are often about 0.1 to 2% active in shampoos, conditioners, and leave-ons, and it is generally stable across mildly acidic to neutral hair-care pH when paired with compatible surfactants or emulsifiers.
