Ppg-7 ●
TL;DR. This ingredient is used mainly as a solvent, humectant, and slip-enhancing carrier in skin, hair, and fragrance-adjacent formulas. It helps dissolve or distribute other materials while giving a light, non-greasy feel.
What does Ppg-7 do in a cosmetic formula?
This ingredient is used mainly as a solvent, humectant, and slip-enhancing carrier in skin, hair, and fragrance-adjacent formulas. It helps dissolve or distribute other materials while giving a light, non-greasy feel.
Is Ppg-7 clean?
Clean-beauty frameworks often flag this type of alkoxylated synthetic polymer because of petrochemical processing and possible trace manufacturing residues if purification is poor. It is generally low-sensitizing at typical cosmetic use levels.
Is Ppg-7 sustainable?
This material is typically petroleum-derived, although bio-based feedstock routes are technically possible. Lower-molecular-weight grades are generally biodegradable, but the sourcing and alkoxylation process weaken its sustainability profile.
Is Ppg-7 COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic propoxylated polymer. Its Green Chemistry fit is mixed, with useful performance and low use-level concerns, but limited renewable sourcing and a more intensive manufacturing route.
How does Ppg-7 work chemically?
The molecule is a short-chain nonionic polyether diol with about seven oxypropylene repeat units, which gives it water compatibility, solvency, and plasticizing behavior. It is broadly stable across normal cosmetic pH ranges and usually compatible with surfactants and polymers, while quality control should address residual epoxide and catalyst residues.
