symphytum officinale leaf extract

Symphytum officinale leaf extract is a water-soluble extract from comfrey leaves, featuring woody odor and used primarily as a cosmetic skin conditioning agent.

General Material Description

Symphytum officinale leaf extract is a botanical extract obtained from the leaves of the comfrey plant, Symphytum officinale L., belonging to the Boraginaceae family. This water-soluble extract exhibits a mild woody and rooty odor at full concentration and is recognized under synonyms such as comfrey leaf extract and Actiphyte of comfrey leaf extract. The extract is primarily utilized in cosmetics for skin conditioning purposes. Comprehensive chemical data and identifiers, including its CAS number 84696-05-9, link to controlled vocabulary entries like those in PubChem, facilitating standardized referencing. The extract is derived through processes that preserve the leaf constituents and is valued for its properties in topical formulations.

Occurrence, Applicability & Potential Uses

Symphytum officinale leaf extract originates from the comfrey plant, which grows in temperate regions and is known historically for topical applications. In contemporary use, the extract is incorporated into cosmetic products primarily for skin conditioning effects. Beyond cosmetics, it is noted for applications such as antidandruff and soothing agents, enhancing scalp and skin formulations. Its use complies with standards like REACH (EU) regulations governing botanical extract ingredients, ensuring safety and efficacy within prescribed concentrations. The mild woody odor profile influences formulation choices where natural aromatic characteristics are desired.

Physico-Chemical Properties Summary

This extract displays a specific gravity ranging roughly from 1.001 to 1.06 at 25 °C, indicating a density close to that of water. It is fully soluble in water, facilitating its integration into aqueous cosmetic formulations. The mild woody and rooty aroma at 100% concentration suggests volatile components influencing sensory perception. These physicochemical characteristics support its compatibility with various topical products, where stability in aqueous solutions is essential. The nature of the extract permits its use without fragrance or flavor application, and understanding its solubility and density aids in precise formulation and quality control.
