Glycine Soja Lipids are the alcohol-soluble fraction of the gummy portion obtained during the refining of soybean oil (Glycine soja, Leguminosae). This lipid blend predominantly consists of phospholipids, sterols, and triglycerides. Glycine Soja Lipids are utilized in cosmetics and skincare products for their emollient, moisturizing, and conditioning properties.

Chemical Composition and Structure:
Glycine Soja Lipids contain a variety of bioactive components:

Phospholipids: Essential for maintaining skin barrier integrity and function. Includes phosphatidylcholine and phosphatidylinositol.
Sterols: Such as beta-sitosterol, which contribute to skin conditioning and barrier protection.
Triglycerides: Neutral fats that provide hydration and nourishment to the skin.

The chemical structure of phospholipids features a hydrophilic head and hydrophobic tails, which support membrane interaction and emulsion stabilization.

Physical Properties:
Glycine Soja Lipids are typically a viscous, oily, or gummy substance with a color ranging from clear to dark yellow, depending on the refining process. They have a characteristic odor and are soluble in organic solvents such as alcohols but are insoluble in water. This blend is known for improving product texture and providing excellent emolliency.

Production Process:

Soybean Oil Collection and Refining: Soybean oil is refined to separate the gummy portion.
Extraction of Alcohol-Soluble Fraction: The gummy portion is treated with alcohol to obtain the lipid fraction.
Purification and Concentration: The lipid blend is purified and concentrated to enhance the quality and consistency of the final product.
Formulation: The purified lipids are incorporated into various cosmetic and skincare products.

Applications:

Cosmetics: Used in creams, lotions, serums, and other skincare products for their emollient and moisturizing properties. They help improve skin texture, maintain hydration, and reinforce the skin barrier.
Pharmaceuticals: Occasionally employed in topical formulations for their conditioning and protective properties.
Functional Foods: Added to nutritional products for their benefits to lipids and skin.

Environmental and Safety Considerations:

Environmental Impact: The production of Glycine Soja Lipids should follow sustainable practices to minimize environmental impact, including responsible waste management and resource use.
Safety: Generally considered safe for topical use. It is important to follow recommended guidelines and dosages to avoid potential allergic reactions or adverse effects. Safety evaluations should be conducted for new formulations or higher concentrations.

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.
