Camellia Japonica Seedcake Extract is an extract derived from the seedcake of Camellia japonica, a plant from the Theaceae family native to East Asia, known for its regenerative properties. After oil extraction from the seeds, the remaining seedcake is processed to obtain an extract containing nutrients, antioxidants, and bioactive compounds. This extract is valued for its emollient, protective, and regenerative qualities, making it suitable for cosmetic formulations aimed at enhancing hydration, elasticity, and radiance in both skin and hair.

Chemical Composition and Structure

This extract contains polyphenols, essential fatty acids, proteins, saponins, and flavonoids. Polyphenols, such as catechin and its derivatives, provide significant antioxidant protection, combating free radicals and reducing signs of aging. Essential fatty acids, including oleic and linoleic acids, improve the skin barrier, supporting hydration and softness. Saponins and flavonoids offer calming and soothing effects on the skin, while proteins nourish and promote cellular renewal.

Physical Properties

It typically appears as a clear or slightly golden liquid, water-soluble, and easily incorporated into a wide range of cosmetic formulations, including serums, lotions, conditioners, masks, and hair care products. Its light, non-greasy texture makes it useful for products that require fast absorption and long-lasting hydration.

Production Process

The production of Camellia Japonica Seedcake Extract begins with the harvesting of Camellia japonica seeds, which are pressed to extract oil. The solid residue, known as seedcake, is then macerated and extracted using solvents or enzymatic processes to isolate bioactive compounds. After extraction, the product is purified, concentrated, and filtered to ensure stable quality and optimal effectiveness in cosmetic use.

Applications

• Medical: Camellia Japonica Seedcake Extract is studied for its anti-inflammatory and antioxidant properties, with potential applications in soothing and reparative treatments for sensitive or irritated skin.

• Cosmetics: Camellia Japonica Seedcake Extract is widely used in skin and hair care products for its nourishing, regenerative, and protective properties. In skincare, it helps improve elasticity, reduce signs of aging, and protect from environmental damage. In hair care, it helps reduce frizz, improve softness, and strengthen hair structure, making it useful for hydrating and regenerative formulations.

INCI Functions:

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.
