Lactis Proteinum

TL;DR. This ingredient is used as a skin- and hair-conditioning protein that can form a light film, improve feel, and support temporary smoothness or manageability.

What does Lactis Proteinum do in a cosmetic formula?

This ingredient is used as a skin- and hair-conditioning protein that can form a light film, improve feel, and support temporary smoothness or manageability.

Is Lactis Proteinum clean?

It is generally acceptable in natural-leaning formulas, but it is animal-derived and does not fit vegan standards. Protein sensitivity is possible for people with relevant dairy allergies, so it has more clean-standard friction than simple plant or mineral ingredients.

Is Lactis Proteinum sustainable?

This material comes from a renewable animal-agriculture source and is expected to be biodegradable. Its sustainability profile depends on dairy supply-chain impacts, including land, water, methane, and animal-welfare practices.

Is Lactis Proteinum COSMOS-approved?

It can align with COSMOS-natural when sourced and processed according to the standard, since derivatives from living animals are generally eligible under conditions. From a Green Chemistry view, it scores well on biodegradability but less cleanly on agricultural footprint and animal-derived sourcing.

How does Lactis Proteinum work chemically?

This compound is a complex mixture of dairy-derived polypeptides with amide-rich backbones that can adsorb onto keratin and skin surfaces through hydrogen bonding and electrostatic interactions. It is typically used at low cosmetic levels as a conditioning additive, and performance depends on protein size, salt load, pH, and preservative compatibility.
