PEG-7 Theobroma Grandiflorum Seed Butter Glyceryl Esters are esters derived from the combination of theobroma grandiflorum seed butter (cupuaçu butter), glycerin, and polyethylene glycol (PEG-7). Theobroma grandiflorum, commonly known as cupuaçu, belongs to the Sterculiaceae family. These esters are highly valued in the cosmetic and personal care industry for their excellent emulsifying, moisturizing, and skin-conditioning properties. They are used to enhance the texture, stability, and overall performance of various skincare and haircare formulations.
Chemical Composition and Structure
PEG-7 Theobroma Grandiflorum Seed Butter Glyceryl Esters contain a blend of fatty acids from cupuaçu seed butter, glycerin, and polyethylene glycol. The specific composition includes:
Essential Fatty Acids: Such as oleic acid and linoleic acid, which are known for their skin-nourishing and moisturizing properties.
Glycerin: A humectant that attracts moisture to the skin and helps maintain hydration.
Polyethylene Glycol (PEG-7): Enhances the solubility and emulsifying properties of the esters.
Phytosterols: Including beta-sitosterol, which provide anti-inflammatory and skin-conditioning benefits.
Polyphenols: Such as catechins, which offer strong antioxidant protection.
Vitamins: Particularly vitamins A, B1, B2, B3, and C, known for their skin-nourishing and antioxidant properties.
Physical Properties
PEG-7 Theobroma Grandiflorum Seed Butter Glyceryl Esters typically appear as a creamy, off-white to pale yellow butter-like substance. They have a smooth texture and are solid at room temperature but melt upon contact with the skin, making them easy to incorporate into various cosmetic formulations.
Cosmetic and Personal Care Applications
Emulsifying: The esters help to stabilize emulsions, allowing oil and water-based ingredients to mix properly and remain stable over time.
Moisturizing: The combination of fatty acids, glycerin, and PEG-7 helps maintain skin hydration and improve the skin barrier function, making it beneficial for dry and sensitive skin.
Skin Conditioning: The esters’ vitamins and minerals help improve the texture and appearance of the skin, making it softer and more resilient.
Anti-Inflammatory: The phytosterols in the esters provide anti-inflammatory benefits, helping to reduce redness and irritation.
Antioxidant Protection: The presence of polyphenols and vitamins helps protect the skin from environmental stressors and free radical damage.
Texture Enhancing: The esters improve the spreadability and feel of cosmetic products, contributing to a smoother application.
Environmental and Safety Considerations
PEG-7 Theobroma Grandiflorum Seed Butter Glyceryl Esters are generally considered safe for use in cosmetic and personal care products. They are well-tolerated by most skin types, including sensitive skin. The production process is environmentally friendly, utilizing sustainable agricultural practices. However, as with all new ingredients, they should be patch-tested before use, especially for those with sensitive skin.
Cosmetics - 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.
