Description

Rosa Davurica Callus Culture Extract is a botanical extract derived from the callus tissue of Rosa davurica, a species of wild rose native to Eastern Asia. Callus tissue, in this context, refers to an undifferentiated plant cell mass cultivated in vitro from the rose’s explants. This extract is valued in cosmetic and skincare formulations for its purported antioxidant and anti-inflammatory properties.

Chemical Composition and Structure:

The chemical composition of Rosa Davurica Callus Culture Extract is complex and not fully elucidated. It typically includes a range of bioactive compounds such as:

Flavonoids: These are polyphenolic compounds known for their antioxidant activities. Common flavonoids in rose extracts include quercetin and kaempferol.
Phenolic Acids: Compounds like caffeic acid and ferulic acid, which contribute to the extract’s antioxidant properties.
Triterpenoids: These include compounds such as ursolic acid, which may have anti-inflammatory effects.
Vitamins and Amino Acids: Essential nutrients that can support skin health.

The precise structure of these compounds varies, but they generally share a common feature of phenolic rings and/or aromatic structures.

Physical Properties:

Appearance: The extract is typically a dark brown to reddish-brown liquid or powder, depending on the formulation and processing.
Odor: It may have a mild, natural floral aroma, characteristic of rose-derived products.
Solubility: It is generally soluble in water and alcohol-based solvents, but insoluble in oils.

Production Process:

Callus Induction: Rosa davurica explants (e.g., leaves or stems) are cultured on a nutrient medium in a controlled environment to induce callus formation.
Callus Propagation: The callus tissue is maintained and propagated in vitro under sterile conditions to ensure a healthy and stable cell mass.
Harvesting: The callus is harvested once a sufficient amount has been produced.
Extraction: The harvested callus is subjected to extraction using solvents such as ethanol or water to obtain the bioactive compounds. This can involve techniques like maceration, ultrasonic extraction, or supercritical fluid extraction.
Purification: The extract may be filtered and concentrated to enhance the potency and remove any residual solvents or impurities.
Formulation: The purified extract is then incorporated into various cosmetic formulations or used as a standalone ingredient.

Applications:

Cosmetics: Often used in facial creams, serums, and masks for its antioxidant, anti-inflammatory, and skin-conditioning properties.
Skincare: Claims include reducing redness, soothing irritated skin, and providing anti-aging benefits.
Pharmaceuticals: Potential applications in formulations targeting skin conditions due to its bioactive compounds.

Environmental and Safety Considerations:

Environmental Impact: The production of plant callus cultures is considered environmentally friendly compared to traditional plant extraction methods, as it reduces the need for large-scale harvesting of wild plants and minimizes habitat disruption.
Safety: Rosa Davurica Callus Culture Extract is generally considered safe for topical use. However, individual sensitivities or allergies to rose-derived products should be considered. It is advisable to perform a patch test before widespread use.

INCI:


Antioxidant agent. Ingredient that counteracts oxidative stress and prevents cell damage. Free radicals, pathological inflammatory processes, reactive nitrogen species and reactive oxygen species are responsible for the ageing process and many diseases caused by oxidation.

Hair conditioning agent. A significant number of ingredients with specific and targeted purposes may co-exist in hair shampoo formulations: cleansers, conditioners, thickeners, matting agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersants that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioning agents includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners. They can perform their task generally accompanied by other different ingredients.

Skin protectant. It creates a protective barrier on the skin to defend it from harmful substances, irritants, allergens, pathogens that can cause various inflammatory conditions. These products can also improve the natural skin barrier and in most cases more than one is needed to achieve an effective result.
