Sh-Polypeptide-9 ●
TL;DR. This ingredient is a recombinant signaling peptide used as a skin-conditioning active, mainly in leave-on formulas that target the look of firmness, smoothness, and post-stress recovery. It is typically included at very low levels within an aqueous serum, gel, or cream base.
What does Sh-Polypeptide-9 do in a cosmetic formula?
This ingredient is a recombinant signaling peptide used as a skin-conditioning active, mainly in leave-on formulas that target the look of firmness, smoothness, and post-stress recovery. It is typically included at very low levels within an aqueous serum, gel, or cream base.
Is Sh-Polypeptide-9 clean?
From a clean-beauty perspective, this ingredient is generally more of a transparency question than a restricted-list issue. Brands should be clear about biotechnology sourcing, purity controls, preservative system, and claims, since peptide-based signaling ingredients can be overclaimed relative to cosmetic evidence.
Is Sh-Polypeptide-9 sustainable?
This material is usually made through controlled biotechnology rather than direct animal sourcing, and the peptide itself is expected to break down into amino-acid fragments. Its sustainability profile depends on fermentation inputs, purification energy, water use, and cold-chain or stability requirements.
Is Sh-Polypeptide-9 COSMOS-approved?
This ingredient is not a straightforward fit for COSMOS-natural or COSMOS-organic formulas, because recombinant biomimetic peptides are outside the usual minimally processed natural ingredient model and may depend on supplier-specific approval details. From a Green Chemistry view, low use levels and biodegradability are positives, while complex purification and biotech processing keep the alignment partial.
How does Sh-Polypeptide-9 work chemically?
The molecule is a recombinant amino-acid polymer designed to mimic a naturally occurring human signaling protein, so its behavior is governed by peptide folding, charge, and water compatibility. It is usually handled in dilute aqueous solution, with best stability in mild pH systems and with protection from high heat, protease contamination, and aggressive preservatives.
