Question 1

What does sh-Polypeptide-7 do in a cosmetic formula?

Accepted Answer

This ingredient is used as a skin-conditioning bioactive, mainly to support formulas positioned around visible firmness, smoothness, and post-procedure-looking recovery. It is not a structural emulsifier, preservative, or solvent, it is added for signaling-style activity at very low levels.

Question 2

Is sh-Polypeptide-7 clean?

Accepted Answer

From a clean beauty perspective, this ingredient is usually treated as acceptable but specialized, with the main questions centered on biotechnology origin, supplier documentation, and low-level preservative residues in the stock solution. It is generally low in irritation potential, although any biologically active protein-like material can be formulation-sensitive and individual reactivity is possible.

Question 3

Is sh-Polypeptide-7 sustainable?

Accepted Answer

This material is typically made through controlled fermentation rather than extraction from animals or large-scale petrochemical synthesis. It should be biodegradable as an amino-acid-based molecule, but the sustainability profile depends on fermentation inputs, purification energy, and the carrier system supplied with it.

Question 4

Is sh-Polypeptide-7 COSMOS-approved?

Accepted Answer

It is not a straightforward COSMOS-organic ingredient, and COSMOS-natural alignment would require supplier-specific proof that the biotechnology route, processing aids, and final material meet the standard’s non-GMO and allowed-processing rules. From a Green Chemistry view, fermentation and biodegradability are positives, while intensive purification and engineered production systems create some friction.

Question 5

How does sh-Polypeptide-7 work chemically?

Accepted Answer

This molecule is a defined recombinant chain of amino acids, so its performance depends on sequence integrity, folding, and protection from heat, strong oxidants, and protein-degrading contamination. It is usually added during cool-down into water-based serums, gels, or emulsions, with formulators keeping pH in a mild skin-compatible range to preserve stability.
