Hydrolyzed Brassica Napus Seedcake Extract

Hydrolyzed Brassica Napus Seedcake Extract is derived from rapeseed (canola) plant material. During processing, the seedcake—the residue left after oil extraction—is hydrolyzed, breaking down its proteins and polysaccharides into smaller, more skin-permeable molecules. This creates an ingredient rich in amino acids and humectant compounds.In skincare formulations, it functions as a skin conditioner. The hydrolyzed peptides and polysaccharides help the skin's surface retain moisture and improve the feel and texture of topical products, contributing to a smoother, softer appearance.

The hydrolyzed peptides and polysaccharides in this extract interact with the outermost layer of skin (the stratum corneum) through hydrogen bonding and other weak intermolecular forces. This allows them to bind water molecules and hold them within the skin, enhancing hydration at the surface level.The amino acids also contribute to the skin's natural moisturising factor, a collection of compounds that naturally maintains skin hydration. By supplementing these compounds topically, the ingredient helps reinforce the skin's inherent ability to retain moisture and maintain a healthy barrier fu…

This ingredient is typically incorporated into serums, moisturisers, and creams at modest concentrations. It works synergistically with other hydrating and barrier-supporting ingredients such as glycerin, ceramides, and hyaluronic acid. As a conditioning agent, it is generally suitable for use twice daily as part of a regular skincare routine, though this depends on the specific formulation and your skin's needs.

This ingredient is generally well-tolerated and considered safe for topical use in cosmetics. Allergic reactions are uncommon but are theoretically possible in individuals with sensitivity to rapeseed or related plants.
