Ingredient Profile & Common Uses
Vaccaria seed extract is produced from the mature seed known commercially as Vaccariae Semen, Cowherb Seed, or Wang Bu Liu Xing. It differs from raw Vaccaria seed powder because selected seed constituents are extracted, concentrated, and dried rather than the whole seed being simply milled. This gives the finished ingredient a distinct commercial identity as a botanical ratio extract.
Commercial grades are mainly differentiated by extract ratio. The 10:1 grade serves as the principal specification, while 4:1 and 5:1 provide lower-ratio options and 20:1 provides a more concentrated format. Extract ratio describes the relationship between starting botanical material and finished extract and should not be interpreted as a vaccarin assay or purity value.
The powder is used in concentrated botanical formulations where reduced botanical bulk and a defined extract format are useful. Its light brown to brown color and dispersible behavior are relevant during development. Dry systems require attention to flow and blend uniformity, while water-containing systems should be evaluated for wetting, suspension, sedimentation, color, and sensory effects.
