Sodium Hyaluronate Crosspolymer-3 is a chemical compound, a special form of hyaluronic acid used in various cosmetic and personal care products. This polymer is created by oxidizing hyaluronic acid to facilitate subsequent crosslinking with propylbisoxyamine, enhancing its moisturizing and anti-aging properties, and providing long-lasting hydration and improved skin elasticity.
Chemical Composition and Structure
Sodium Hyaluronate Crosspolymer-3 is the sodium salt of hyaluronic acid that has been oxidized to enable crosslinking with propylbisoxyamine. This process forms a three-dimensional network that significantly enhances the molecule's ability to retain water, offering sustained hydration. The chemical structure includes oxidized hyaluronic acid molecules interconnected by propylbisoxyamine, creating a robust and flexible polymer network.
Physical Properties
Sodium Hyaluronate Crosspolymer-3 typically appears as a white or off-white powder. It is highly soluble in water, forming a gel-like substance when hydrated. This gel provides a smooth, non-greasy texture, making it suitable for various cosmetic formulations. The crosslinked structure offers improved stability and a controlled release of moisture over time.
Chemical Industrial Synthesis Process
What it is used for and where
Cosmetics - INCI Functions
Humectant. Hygroscopic compound 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 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: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.
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.
Applications
Moisturizers and Creams: Sodium Hyaluronate Crosspolymer-3 is widely used in moisturizers and creams for its ability to provide long-lasting hydration. It forms a protective barrier on the skin, reducing transepidermal water loss and keeping the skin hydrated.
Anti-Aging Products: Due to its excellent water retention properties, this ingredient is commonly found in anti-aging products. It helps to plump the skin, reducing the appearance of fine lines and wrinkles, and improving overall skin elasticity.
Serums and Essences: In serums and essences, Sodium Hyaluronate Crosspolymer-3 acts as a powerful hydrating agent, enhancing the delivery and effectiveness of active ingredients.
Sun Care: It is also used in sun care products to provide hydration and soothing effects, helping to protect the skin from the drying effects of sun exposure.
Eye Creams and Gels: The ingredient is ideal for use in eye creams and gels due to its gentle yet effective moisturizing properties, helping to reduce puffiness and dark circles.
Safety
Sodium Hyaluronate Crosspolymer-3 is generally considered safe for use in cosmetic and personal care products. It is non-irritating and suitable for all skin types, including sensitive skin. The ingredient is biodegradable and poses minimal risk to the environment when disposed of properly. As with all cosmetic ingredients, it is important to use it within the recommended guidelines to ensure safety and efficacy.
