myrica rubra leaf/stem extract

Myrica rubra leaf/stem extract is a plant-derived cosmetic ingredient obtained from the leaves and stems of the myrica rubra tree, noted for its antioxidant and skin-conditioning properties.

General Material Description

Myrica rubra leaf/stem extract is a botanical extract obtained from the leaves and stems of the myrica rubra tree, belonging to the family Myricaceae. This extract exhibits a sour flavor note and is known by various synonyms such as chinese bayberry leaf/stem extract, red bayberry leaf/stem extract, mountain peach leaf/stem extract, and yumberry leaf/stem extract. The extract is used predominantly in cosmetic formulations where it functions as an antioxidant and skin-conditioning agent. It is documented under [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/Myrica-rubra) as a plant-derived natural extract, sourced from the bayberry plant native to East Asia, especially China. The extract's composition supports potential applications in emollient and bleaching cosmetic products.

Occurrence, Applicability & Potential Uses

Myrica rubra leaf/stem extract is sourced from the bayberry tree primarily found in East Asia. The extract is utilized in cosmetics as an antioxidant, skin conditioning agent, emollient, and skin protectant. Its inclusion in formulations benefits skin conditioning and potential depigmenting effects, making it relevant in bleaching cosmetic agents as well. Usage is aligned with cosmetic regulations such as REACH (EU), which governs the safety and allowable compounds in personal care products within the European Union. The extract is not approved for use in fragrances or flavors, limiting its application to topical cosmetic agents.

Physico-Chemical Properties Summary

Myrica rubra leaf/stem extract is a plant-derived liquid or semi-solid, characterized by a sour flavor profile. Its antioxidant capacity supports formulation stability and skin protective function. The extract’s physicochemical nature suggests solubility in aqueous or hydroalcoholic solvents, facilitating its integration into skin conditioning and bleaching products. The absence of identified hazard classifications under OSHA HCS implies a generally safe profile but with undetermined detailed toxicological data for oral, dermal, or inhalation routes. Formulators must consider the extract's reactivity, compatibility with other ingredients, and recommended usage levels confined to cosmetic topical applications.

FAQ

What is myrica rubra leaf/stem extract and what are its main synonyms?
Myrica rubra leaf/stem extract is a botanical extract obtained from the leaves and stems of the myrica rubra plant, a member of the Myricaceae family. It is commonly known as chinese bayberry leaf/stem extract, red bayberry leaf/stem extract, mountain peach leaf/stem extract, yangmei yamamomo leaf/stem extract, and yumberry leaf/stem extract. The extract is recognized for its sour flavor note and is mainly used in cosmetic formulations for its antioxidant and skin-conditioning properties.
How and where is myrica rubra leaf/stem extract typically used, and from what source is it derived?
This extract is derived from the leaves and stems of the bayberry tree, naturally found in East Asia, including China. It is primarily incorporated into cosmetic agents where it serves antioxidant and skin-conditioning roles. The extract functions as an emollient and skin protectant, also used in bleaching cosmetic products. Usage is strictly topical and restricted from fragrance and flavor applications, reflecting its designated purpose in cosmetic formulations.
What regulations and safety considerations apply to myrica rubra leaf/stem extract in cosmetic use?
Myrica rubra leaf/stem extract is subject to cosmetic regulations such as REACH (European Union), which oversees the safety of ingredients in personal care products. Safety data indicate no classified hazards under OSHA's Hazard Communication Standard (29 CFR 1910) and no identified specific precautionary labeling. The extract's toxicological profile via oral, dermal, or inhalation routes remains undetermined, directing formulators to limit its use to recommended cosmetic topical levels. Additionally, it is not approved for use as a fragrance or flavor ingredient, which further defines its regulated scope.
