Oleic/Linoleic/Linolenic polyglycerides are derived from the esterification of polyglycerol with a blend of fatty acids including oleic, linoleic, and linolenic acids. These polyglycerides are highly valued in the cosmetic and personal care industry for their emollient, moisturizing, and skin conditioning properties, making them beneficial components in various skincare, hair care, and makeup products.
Chemical Composition and Structure
Oleic/Linoleic/Linolenic Polyglycerides contain a mixture of fatty acids esterified with polyglycerol. The specific composition includes:
Oleic Acid: A monounsaturated fatty acid known for its emollient and moisturizing properties.
Linoleic Acid: A polyunsaturated fatty acid that provides anti-inflammatory and barrier-repair benefits.
Linolenic Acid: An essential fatty acid that contributes to skin health and anti-inflammatory properties.
Polyglycerol: Acts as a backbone for esterification, enhancing the hydrophilic and hydrophobic balance of the molecule.
Physical Properties
Oleic/Linoleic/Linolenic Polyglycerides typically appear as a light yellow to amber liquid. They are oil-soluble, making them easy to incorporate into various oil-based and emulsion formulations.
Cosmetic and Personal Care Applications
Emollient: Provides a smooth, non-greasy feel on the skin, improving texture and hydration. It helps to form a protective barrier that prevents moisture loss, making it suitable for dry and sensitive skin types.
Moisturizing: The blend of fatty acids helps to lock in moisture, maintaining the skin's hydration and preventing dryness.
Skin Conditioning: This ingredient helps to condition the skin, enhancing its texture and overall appearance. It is suitable for all skin types, especially dry and mature skin.
Anti-Inflammatory: Linoleic and linolenic acids provide anti-inflammatory benefits, helping to soothe and calm irritated skin.
Hair Care: In hair care products, Oleic/Linoleic/Linolenic Polyglycerides help to nourish the scalp, improve hair strength, and enhance the shine and smoothness of the hair.
Formulation Stabilizer: Improves the stability and shelf life of formulations by enhancing the emulsification and texture of products.
Environmental and Safety Considerations
Oleic/Linoleic/Linolenic Polyglycerides are generally considered safe for use in cosmetic and personal care products. They are non-irritating and suitable for all skin types. As naturally derived ingredients, they pose minimal risk to the environment when disposed of properly. Utilizing these polyglycerides also supports sustainable practices by promoting the use of plant-based ingredients.
Cosmetics - INCI Functions
Binder agent. Ingredient that is used in cosmetic, food and pharmaceutical products as an anti-caking agent with the function of making the product in which it is incorporated silky, compact and homogenous. The binder, either natural such as mucilage, gums and starches or chemical, may be in the form of a powder or liquid.
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.
Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
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.
