Hydrolyzed Camellia Japonica Seed Oil Extract is an extract of Camellia japonica seed oil that has undergone hydrolysis to break down lipid molecules into smaller components, enhancing skin penetration and absorption. This extract contains essential fatty acids and polypeptides that provide antioxidant, emollient, hydrating, and nourishing properties. It is particularly suitable for cosmetic formulations for skin and hair, promoting hydration and protection without a greasy effect.

Chemical Composition and Structure

The hydrolyzed extract consists of essential fatty acids, such as oleic and linoleic acids, along with small peptides and amino acids. The hydrolysis process makes these molecules more readily absorbable, providing deep hydration and supporting the skin's barrier function.

Physical Properties

Hydrolyzed Camellia Japonica Seed Oil Extract appears as a clear, water-soluble liquid and is easily incorporated into serums, lotions, and creams. Its lightweight consistency makes it ideal for products requiring long-lasting hydration and a nourishing effect without oily residue.

Production Process

The extract is produced by enzymatically hydrolyzing Camellia japonica seed oil, which breaks down lipids into smaller components, preserving bioactive properties and enhancing skin absorption.

Applications

• Medical: Known for its emollient and hydrating properties, with potential applications in treatments for dry or damaged skin.

• Cosmetics: Hydrolyzed Camellia Japonica Seed Oil Extract is used in skin and hair care products for its moisturizing and nourishing qualities. It helps maintain skin hydration, improve texture, and strengthen the skin barrier, making it ideal for serums, lotions, and hair treatments.

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.

• Industry: In the cosmetic industry, it is valued for providing hydration without a greasy feel, finding applications in lightweight, fast-absorbing formulations.

Environmental and Safety Considerations
Hydrolyzed Camellia Japonica Seed Oil Extract is considered safe for cosmetic use and is biodegradable. As a plant-based derivative, it has minimal environmental impact, especially when Camellia japonica seeds are sustainably sourced.
