What Is Brassica Oleracea Capitata Leaf Water?

Brassica Oleracea Capitata Leaf Water is a clear liquid obtained by steam-distilling the leaves of the common cabbage plant, Brassica oleracea var capitata. During distillation the aromatic steam that passes through the leaves condenses into a mild, nutrient-rich water. This condensate carries trace amounts of naturally occurring vitamins C and K, B-group vitamins, sulfur-based compounds, polyphenols and essential minerals that are already present in fresh cabbage leaves.

Cabbage has a long folk history as a soothing poultice for minor skin troubles. As cosmetic science advanced formulators began looking for gentle botanical waters that could replace plain water while offering added skin benefits. Leaf waters became popular because they let brands market a plant-powered story without relying on strong extracts or essential oils. Brassica Oleracea Capitata Leaf Water fits perfectly into this trend and is now produced in modern facilities where cleaned cabbage leaves are steam-distilled, then the condensate is filtered and preserved for use in skin care.

You will most often spot this ingredient in hydrating toners, facial mists, sheet masks, light moisturizers, after-sun gels and age-defense serums where a calm, replenishing base is desired.

Only poorly preserved finished products could pose a breakout risk since microbial overgrowth may irritate skin, but that stems from formulation issues rather than the ingredient itself.
