Description

Calendula Officinalis Callus Extract is derived from callus cultures of the Calendula officinalis plant, commonly known as Calendula or Marigold. This extract is rich in active compounds and is used in cosmetic and skincare products for its soothing and regenerative properties.

Chemical Composition and Structure:

Key Components: The callus extract contains a high concentration of flavonoids, triterpenoids, carotenoids, and other phenolic compounds. Major components include calendulin, quercetin, and various other flavonoids.
Structure: The chemical structure of these compounds supports the extract’s anti-inflammatory, antioxidant, and regenerative effects.

Physical Properties:

Appearance: The extract typically appears as a yellowish or amber solution, depending on the extraction method and concentration.
Odor: It has a light, floral fragrance with herbal notes.
Solubility: Soluble in organic solvents and some aqueous formulations, it can be easily incorporated into various cosmetic products.

Production Process:

Cultivation: Calendula callus cells are cultured under controlled conditions to enhance the production of active compounds.
Extraction: The callus is treated with specific solvents to extract bioactive compounds. Common methods include organic solvent extraction or advanced technologies like supercritical CO2 extraction.
Purification: The extract is purified to remove impurities and concentrate the active components.
Formulation: The purified extract is incorporated into cosmetic products such as serums, creams, and lotions.

Applications:

Cosmetics: Used in skincare products for its soothing, regenerative, and anti-inflammatory properties. It is particularly suitable for sensitive and irritated skin.
Skincare: Included in formulations to improve skin texture, promote healing, and reduce redness and inflammation.
Hair Care: May be added to hair products to soothe the scalp and improve hair health.

Environmental and Safety Considerations:

Environmental Impact: The production of Calendula callus extract is generally sustainable if conducted following responsible agricultural practices and eco-friendly production processes.
Safety: Generally regarded as safe for topical use. However, like all botanical extracts, it should be used according to established guidelines to avoid potential allergic reactions or skin irritations. Safety assessments are recommended for new formulations or high concentrations.

INCI Functions:


Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.

Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.

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.
