Bis-Peg/Ppg-16/16 Peg/Ppg-16/16 Dimethicone ●
TL;DR. This ingredient is primarily a nonionic emulsifier and dispersing aid, used to stabilize water-in-oil or water-in-siloxane systems and improve slip in skin care, makeup, and sunscreen formulas.
What does Bis-Peg/Ppg-16/16 Peg/Ppg-16/16 Dimethicone do in a cosmetic formula?
This ingredient is primarily a nonionic emulsifier and dispersing aid, used to stabilize water-in-oil or water-in-siloxane systems and improve slip in skin care, makeup, and sunscreen formulas.
Is Bis-Peg/Ppg-16/16 Peg/Ppg-16/16 Dimethicone clean?
From a clean-beauty perspective, it has friction because it combines a synthetic organosilicon backbone with ethoxylated and propoxylated segments, which can raise processing-residue questions such as ethylene oxide or 1,4-dioxane control. It is generally considered low-irritation on skin, but it is not a clean-standard favorite because of its synthetic profile and restricted-list overlap in some frameworks.
Is Bis-Peg/Ppg-16/16 Peg/Ppg-16/16 Dimethicone sustainable?
This material is petrochemical and mineral-derived rather than renewable, and its organosilicon backbone is not readily biodegradable. Its environmental profile is weaker than plant-derived emulsifiers because persistence is the main concern.
Is Bis-Peg/Ppg-16/16 Peg/Ppg-16/16 Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. It fits poorly with Green Chemistry priorities because it relies on synthetic petrochemical processing, ethoxylation or propoxylation chemistry, and a poorly biodegradable polymer backbone.
How does Bis-Peg/Ppg-16/16 Peg/Ppg-16/16 Dimethicone work chemically?
The molecule is a high-molecular-weight organosilicon polymer modified with polyethylene glycol and polypropylene glycol side chains, giving it both oil-compatible and water-compatible regions for interfacial stabilization. Typical use is often around 0.5% to 5% depending on emulsion type, and as a nonionic polymeric emulsifier it is generally pH-tolerant but must be matched carefully with the oil phase, electrolytes, and other surfactants for stable viscosity and droplet size.
