Camellia Japonica Seed Oil Triacetin Esters is a derivative of Camellia japonica seed oil that has been chemically modified for a lighter consistency and enhanced stability. These esters are valued for their emollient and lubricating properties, offering a silky, dry feel on the skin. They are particularly useful in cosmetic formulations that require non-greasy hydration and fast absorption.

Chemical Composition and Structure

The esters consist of fatty acids esterified with triacetin, giving the oil a lighter texture and greater oxidative stability. This structure enhances the emollient quality of the oil, improving distribution and providing a silky touch to the product.

Physical Properties

Camellia Japonica Seed Oil Triacetin Esters appear as a clear, lightweight liquid, oil-soluble, and are ideal for incorporation into serums, lotions, and creams. Their silky, non-greasy texture makes them perfect for products that require a dry feel and even skin distribution.

Production Process

The esters are produced by esterifying Camellia japonica seed oil with triacetin. This process modifies the oil's physical properties, making it lighter and more stable without altering its emollient and hydrating qualities.

Applications

• Medical: Known for its emollient and lubricating properties, with potential applications in treatments for dry and delicate skin.

• Cosmetics: Camellia Japonica Seed Oil Triacetin Esters are commonly used in skincare products for their emollient qualities, imparting a silky feel without an oily residue. They are ideal in serums, lightweight creams, and makeup products due to their dry texture and quick absorption.

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.

• Industry: In the cosmetic industry, they are valued for providing a light, silky touch, finding applications in advanced formulations requiring a non-greasy effect.

Environmental and Safety Considerations
Camellia Japonica Seed Oil Triacetin Esters are considered safe for cosmetic use and are biodegradable. Being derived from a sustainable plant source, they have minimal environmental impact, especially when Camellia japonica seeds are responsibly sourced.
