Description

Soluble proteoglycan is a glycoprotein found in various tissues of the body, including the skin, cartilage, and connective tissues. It is highly valued in the cosmetic and personal care industry for its moisturizing, skin conditioning, and anti-aging properties, making it a beneficial component in various skincare and hair care products.

Chemical Composition and Structure
Soluble proteoglycans consist of a core protein with one or more covalently attached glycosaminoglycan (GAG) chains. These GAG chains, such as hyaluronic acid, chondroitin sulfate, and dermatan sulfate, contribute to the unique properties of proteoglycans. The specific composition includes:

Core Protein: Provides the structural framework for the attachment of GAG chains.
Glycosaminoglycan (GAG) Chains: Hyaluronic acid, chondroitin sulfate, and dermatan sulfate, known for their hydrating and skin-conditioning properties.
Physical Properties
Soluble proteoglycans typically appear as a clear to slightly opalescent liquid. They are water-soluble, making them easy to incorporate into various water-based cosmetic formulations.

Cosmetic and Personal Care Applications
Moisturizing: The high GAG content provides strong moisturizing benefits, helping to maintain the skin's hydration and improve its elasticity.

Skin Conditioning: This ingredient helps to condition the skin, enhancing its texture and overall appearance. It is suitable for all skin types.

Anti-Aging: The presence of hyaluronic acid and other GAGs helps to reduce the appearance of fine lines and wrinkles by maintaining skin hydration and promoting collagen synthesis.

Soothing: Soluble proteoglycans help to soothe and calm the skin, providing relief from irritation and discomfort.

Hair Care: In hair care products, soluble proteoglycans help to nourish the scalp, improve hair strength, and enhance the shine and smoothness of the hair.

Wound Healing: The GAG chains in proteoglycans contribute to their role in wound healing by promoting cell proliferation and tissue repair.

Environmental and Safety Considerations

Soluble proteoglycans are generally considered safe for use in cosmetic and personal care products. They are non-irritating and suitable for all skin types. As a natural component derived from biological sources, they pose minimal risk to the environment when disposed of properly. Utilizing soluble proteoglycans also supports sustainable practices by promoting the use of naturally derived ingredients.

Cosmetics - INCI Functions


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.

Hair conditioning agent. A significant number of ingredients with specific and targeted purposes may co-exist in hair shampoo formulations: cleansers, conditioners, thickeners, matting agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersants that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioning agents includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners. They can perform their task generally accompanied by other different ingredients.
