Question 1

What does sh-Oligopeptide-1 do in a cosmetic formula?

Accepted Answer

This ingredient is a skin-conditioning signal peptide used in leave-on products to support the appearance of smoother texture, improved firmness, and post-treatment recovery. It is typically used at very low levels in serums, creams, and ampoules rather than as a structural moisturizer or exfoliant.

Question 2

Is sh-Oligopeptide-1 clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally treated as acceptable but nuanced because it is bioengineered and biologically active in concept, even though topical use levels are very low. It is not a common allergen, but brands often assess it closely for source, purity, preservation system, and claims language.

Question 3

Is sh-Oligopeptide-1 sustainable?

Accepted Answer

This material is usually made through biotechnology rather than mined or petroleum-derived bulk chemistry, and the finished molecule is expected to break down like other peptides. Its sustainability profile depends on fermentation inputs, purification energy, and whether recombinant production methods meet a given standard’s sourcing rules.

Question 4

Is sh-Oligopeptide-1 COSMOS-approved?

Accepted Answer

This ingredient is not a straightforward fit for COSMOS-organic or COSMOS-natural when produced through recombinant genetic engineering, since COSMOS has strict rules around biotechnology and genetically modified systems. From a Green Chemistry view, it has positives such as very low use levels and biodegradability, but standard alignment depends heavily on the production platform and documentation.

Question 5

How does sh-Oligopeptide-1 work chemically?

Accepted Answer

The molecule is a 53-amino-acid, disulfide-rich peptide with a molecular weight around 6.2 kDa, which limits passive skin penetration and makes formulation delivery and barrier condition important. It is commonly used in the ppm range, is best handled in water-based systems with gentle processing, and can lose activity under high heat, extreme pH, oxidizing conditions, or protease contamination.
