Camellia Japonica Oleosomes are natural lipid structures derived from the seeds of Camellia japonica, serving as reservoirs for fatty acids, vitamins, and antioxidants. These oleosomes provide prolonged hydration and nutrient release, making them particularly suitable for moisturizing and regenerative formulations with lasting effects on skin and hair.
Chemical Composition and Structure
Oleosomes contain a good amount of essential fatty acids like oleic acid, vitamin E, and other phytonutrients. Their unique lipid structure enables controlled nutrient release, ensuring long-lasting hydration and protection from free radicals. Vitamin E adds antioxidant effects, helping keep the skin soft and nourished.
Physical Properties
Camellia Japonica Oleosomes appear as lipid microspheres, insoluble in water, and easily incorporated into serums, creams, lotions, and masks. Their gradual release capacity makes them ideal for formulations requiring prolonged hydration and protective effects.
Production Process
Oleosomes are extracted from Camellia japonica seeds through a gentle process that preserves their bioactive and lipid properties. After extraction, they are purified to ensure stability and quality, making them suitable for cosmetic applications.
Applications
Medical: Known for their prolonged release of hydration and nutrients, with potential applications in treatments for dry or damaged skin.
Cosmetics: Camellia Japonica Oleosomes are used in skin and hair care products for their hydrating, nourishing, and protective properties. They provide long-lasting hydration and protection against oxidative stress, making them suitable for serums, creams, and hair treatments.
INCI Functions:
Skin conditioning agent - Humectant. Humectants are hygroscopic substances 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 the 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: corneum, the most superficial, lucidum, granulosum, spinosum and basale. Humectants have the ability to retain in the stratum corneum the water they attract from the air and have the function of moisturising the skin. It is better to use them before emollients that are oil-based.
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.
Emulsion stabiliser. Emulsions are thermodynamically unstable. Emulsion stabilisers improve the formation and stability of single and double emulsions. as well as their shelf-life. It should be noted that in the structure-function relationship, the molar mass of the ingredient used plays an important role.

Industry: In the cosmetic industry, oleosomes are valued for their controlled release of active ingredients, finding applications in advanced formulations for deep skincare.
Environmental and Safety Considerations
Camellia Japonica Oleosomes are considered safe for cosmetic use and are biodegradable. As they are derived from plant seeds, they have minimal environmental impact, especially when Camellia japonica seeds are sustainably sourced to support responsible production.
