Hibiscus Rosa-Sinensis Extract is obtained from the flowers of Hibiscus rosa-sinensis, commonly known as hibiscus or Chinese rose. This extract is highly valued in cosmetic and skincare formulations for its antioxidant, hydrating, and toning properties. It is used in various beauty and skincare products to improve skin appearance and health.

Chemical Composition and Structure:
The extract from Hibiscus rosa-sinensis contains several bioactive compounds, including:

Flavonoids: Such as quercetin and anthocyanins, which provide antioxidant and anti-inflammatory effects.
Phenolic Acids: Including caffeic acid and chlorogenic acid, which enhance the extract's antioxidant properties and protect the skin from oxidative stress.
Organic Acids: Such as citric acid and malic acid, which offer exfoliating properties and help balance skin pH.
Polysaccharides: Which provide moisturizing and skin-conditioning benefits.
Vitamins: Particularly vitamin C, which supports skin health and collagen synthesis.
Saponins: Compounds that may have anti-inflammatory and skin-supportive effects.

These compounds typically feature aromatic rings for flavonoids and phenolic acids, and complex structures for polysaccharides and saponins.

Physical Properties:

Appearance: The extract is usually a liquid that can range from light yellow to deep red, depending on the concentration and extraction method.
Odor: It has a natural, mildly floral scent characteristic of hibiscus flowers.
Solubility: Soluble in water and alcohol-based solvents; generally insoluble in oils.

Production Process:

Harvesting: Hibiscus rosa-sinensis flowers are collected at peak bloom to ensure the highest concentration of active compounds.
Extraction: The flowers are processed to extract their bioactive components using solvents such as water or ethanol, or advanced methods like ultrasonic or supercritical fluid extraction.
Purification: The extract is purified to remove impurities and concentrate the active ingredients, typically through filtration and concentration processes.
Formulation: The purified extract is incorporated into various cosmetic and skincare formulations, including serums, creams, and masks.

Applications:

Cosmetics: Used in facial products like serums, moisturizers, and masks for its antioxidant, hydrating, and toning properties.
Skincare: Beneficial for hydrating the skin, reducing signs of aging, improving skin texture, and protecting against environmental damage.
Haircare: Can be included in shampoos and conditioners to provide conditioning and strengthening benefits.

Environmental and Safety Considerations:

Environmental Impact: The production of Hibiscus Rosa-Sinensis Extract is generally sustainable if the flowers are cultivated responsibly and the extraction processes are managed in an environmentally friendly manner.
Safety: Hibiscus Rosa-Sinensis Extract is generally safe for topical use and is well-tolerated by most skin types.

INCI:


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.

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.
