Hydrolyzed Vegetable Protein PG-Propyl Silanetriol is a modified vegetable protein that has been hydrolyzed to enhance its ability to penetrate and condition hair and skin. This ingredient combines hydrolyzed proteins with propyl silanetriol, a silicone derivative, to provide nourishing and protective benefits.

Chemical Composition and Structure

The chemical composition of Hydrolyzed Vegetable Protein PG-Propyl Silanetriol includes:

• Hydrolyzed Vegetable Protein: Derived from plant sources (such as soy or wheat), providing amino acids that are essential for hair and skin health.
• PG-Propyl Silanetriol: A silicone compound that improves moisture retention and smoothness of hair and skin while offering conditioning properties.

Structurally, this ingredient features a combination of protein chains and silicone, allowing it to provide both nourishment and a protective barrier.

Physical Properties

• Appearance: Typically a clear to slightly yellow liquid.
• Solubility: Soluble in water and compatible with various cosmetic formulations.
• pH: Generally neutral to slightly acidic, depending on the specific formulation.
• Odor: Mild, characteristic of plant-based ingredients.
• Stability: Stable under normal storage conditions but should be protected from extreme temperatures and direct sunlight.

Production Process

• Hydrolysis: The vegetable protein is hydrolyzed using enzymatic or chemical methods to break down the protein chains into smaller peptides.
• Modification: The hydrolyzed protein is then reacted with propyl silanetriol to create a modified ingredient that enhances its conditioning properties.
• Formulation: The resulting compound is incorporated into hair and skin care products, often combined with other ingredients for improved efficacy and stability.

Applications

• Medical: Occasionally used in formulations aimed at repairing and nourishing damaged hair and skin.
• Cosmetics: Commonly included in shampoos, conditioners, and moisturizers for its conditioning and protective effects.

INCI Functions:

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.

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.

• Industrial Uses: Limited applications, primarily in formulations for natural products.

Environmental and Safety Considerations

Hydrolyzed Vegetable Protein PG-Propyl Silanetriol is generally regarded as safe for topical application in cosmetics when used according to recommended guidelines. It is well-tolerated by most skin types, but individuals with specific allergies to the source plants should exercise caution. Responsible sourcing and production practices are essential to ensure that the ingredient is free from harmful contaminants and produced sustainably.
