Description

Althaea Rosea Callus Extract is derived from the callus tissue of the Althaea rosea plant, commonly known as Hollyhock. This extract is produced using tissue culture techniques, where callus cells are grown in a controlled environment to yield beneficial compounds. Althaea Rosea Callus Extract is utilized in cosmetics and personal care products for its soothing, moisturizing, and anti-inflammatory properties.

Chemical Composition and Structure:
Althaea Rosea Callus Extract contains a range of bioactive compounds, including:

Polysaccharides: Provide excellent hydrating and film-forming properties, which help to retain moisture and create a protective barrier on the skin.
Flavonoids: Offer antioxidant and anti-inflammatory effects, protecting the skin from oxidative stress and reducing inflammation.
Saponins: Contribute to the soothing and emollient properties of the extract, enhancing skin texture.
Phenolic Compounds: Present in the callus tissue, providing additional antioxidant protection and supporting overall skin health.
Vitamins: Essential vitamins found in the callus of Althaea rosea, such as vitamin C, contribute to skin nourishment and regeneration.

Physical Properties:

Appearance: Typically a clear to slightly yellow or beige liquid, or a gel-like substance.
Odor: Mild, neutral, or slightly floral aroma depending on the formulation and concentration.
Solubility: Generally soluble in water, making it suitable for incorporation into aqueous-based formulations.

Production Process:

Callus Culturing: The Althaea rosea plant tissue is cultured in vitro to develop callus cells. This process involves growing the cells in a nutrient-rich medium under controlled conditions.
Harvesting: Once the callus tissue has grown sufficiently, it is harvested for extraction.
Extraction: The active compounds are extracted from the callus tissue using appropriate solvents or extraction methods.
Filtration: The extract is filtered to remove any residual plant material, resulting in a clear, stable product.
Formulation: The final extract is incorporated into various cosmetic and personal care products.

Applications:

Cosmetics: Used in skincare products for its soothing, hydrating, and anti-inflammatory properties.
Skincare: Beneficial for calming irritated skin, providing deep hydration, and improving overall skin texture.
Haircare: Can be included in hair care products to enhance moisture, soothe the scalp, and improve hair health.

Environmental and Safety Considerations:

Environmental Impact: The production of Althaea Rosea Callus Extract generally has a minimal environmental impact. Sustainable practices in tissue culturing and extraction are recommended to further reduce environmental effects.
Safety: This ingredient is generally considered safe for use in cosmetics and personal care products when used as directed. It is well-tolerated by most skin types. People allergic to plants of the Malvaceae family or with very sensitive skin should be cautious.

INCI:


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.

Humectant. Hygroscopic compound used to minimise water loss in the skin and to prevent it from drying out by facilitating faster and greater absorption of water into the stratum corneum of the epidermis. The epidermis is the most superficial of the three layers that make up human skin (epidermis, dermis and hypodermis) and is the layer that maintains hydration in all three layers. In turn, the epidermis is composed of five layers: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.

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.
