Hibiscus Rosa-Sinensis Flower/Leaf Extract is obtained from both the flowers and leaves of Hibiscus rosa-sinensis, commonly known as hibiscus or Chinese rose. This extract is used in a variety of cosmetic and skincare products for its antioxidant, anti-inflammatory, astringent, and hydrating properties. It is appreciated for its potential to enhance skin health and overall appearance.

Chemical Composition and Structure:
The extract from Hibiscus rosa-sinensis flowers and leaves contains a range of bioactive compounds, including:

Flavonoids: Such as quercetin, kaempferol, and anthocyanins, which provide antioxidant and anti-inflammatory benefits.
Phenolic Acids: Including caffeic acid and chlorogenic acid, which contribute to the extract’s antioxidant properties and help protect the skin from oxidative stress.
Organic Acids: Such as citric acid and malic acid, which offer mild exfoliating effects and help maintain skin pH balance.
Polysaccharides: Which provide moisturizing and skin-conditioning benefits.
Vitamins: Including vitamin C, which supports skin health and collagen synthesis.
Triterpenoids: Such as ursolic acid, which has anti-inflammatory and soothing properties.

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

Physical Properties:

Appearance: The extract is typically a viscous liquid that can range from light to dark brown, depending on the concentration and extraction method.
Odor: It has a mild, floral and herbal scent characteristic of hibiscus flowers and leaves.
Solubility: Soluble in water and alcohol-based solvents; generally insoluble in oils.

Production Process:

Harvesting: Hibiscus rosa-sinensis flowers and leaves are collected, usually at their peak freshness, to ensure a high concentration of active compounds.
Extraction: Both flowers and leaves are processed to extract their bioactive components using solvents like water or ethanol, or advanced methods such as 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 products, including serums, creams, and masks.

Applications:

Cosmetics: Used in facial products such as serums, moisturizers, and masks for its antioxidant, anti-inflammatory, astringent, and hydrating properties.

INCI:


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.

Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.
