Description

Polyglyceryl-3 Pentaolivate is a cosmetic ingredient that serves as an emulsifier and skin conditioner. It is the pentaester formed from the reaction of polyglycerol-3 with olive acid, derived from olive oil. This ingredient is used in a variety of cosmetic formulations to enhance the texture and moisturizing properties of products, making them more nourishing and hydrating for the skin.

Chemical Composition and Structure

This compound is created by esterifying polyglycerol-3, a polymer of glycerol, with olive acid, which is primarily composed of oleic acid, a monounsaturated fatty acid found in olive oil. This results in a molecule with excellent emollient and skin-conditioning properties, which can effectively stabilize emulsions and enhance skin absorption.

Physical Properties

Polyglyceryl-3 Pentaolivate typically appears as a viscous, clear to slightly yellow liquid. It is highly soluble in oils and has moderate solubility in water, facilitating its use in both oil-based and water-based cosmetic formulations. It is known for its smooth texture and ability to form stable emulsions.

Production Process

Synthesis: The esterification process involves reacting polyglycerol-3 with fatty acids derived from olive oil. This reaction typically occurs in the presence of a catalyst under controlled temperature and pressure conditions to form the pentaester.
Purification: Following synthesis, the product undergoes purification to remove any unreacted materials, byproducts, or impurities to ensure a high level of purity and efficacy.
Quality Control: The final product is subjected to various quality control tests, including purity analysis and performance assessments, to ensure it meets industry standards for cosmetic use.

Applications

Cosmetic Products: Polyglyceryl-3 Pentaolivate is used in creams, lotions, and serums, where it acts as an effective emulsifier and moisturizer, improving product consistency and skin-feel.
Skin Care: It is particularly valued in skincare products for its moisturizing benefits, helping to restore the skin's barrier and increase hydration.
Make-up: Employed in make-up formulations, it helps to enhance the spreadability and blending of products on the skin.

Environmental and Safety Considerations

Polyglyceryl-3 Pentaolivate is considered safe for cosmetic use and is typically well-tolerated by the skin. It is derived from renewable resources and is biodegradable, contributing to its environmental friendliness. As with all cosmetic ingredients, it is recommended to use this compound within specified concentrations to avoid any potential skin sensitivities.

INCI


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.

Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable and are used to soothe or soften the skin and emulsify, so they need a specific, stabilising ingredient. This ingredient forms a film, lowers the surface tension and makes two immiscible liquids miscible. A very important factor affecting the stability of the emulsion is the amount of the emulsifying agent. Emulsifiers have the property of reducing the oil/water or water/oil interfacial tension, improving the stability of the emulsion and also directly influencing the stability, sensory properties and surface tension of sunscreens by modulating the filmometric performance.

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.
