Chemical Composition and Structure

Chemical Composition: Bis-Aminopropyl Diglycol Dimaleate consists of a bis-aminopropyl structure linked to diglycol and dimaleate groups. This chemical configuration helps in forming cross-links between hair proteins, which aids in strengthening and repairing the hair fiber.

Structure: The compound has a molecular structure that includes two amino groups (bis-aminopropyl), a glycol group, and two maleic acid derivatives (dimaleate). This structure allows it to interact effectively with hair proteins and other components in hair care formulations.

Physical Properties

Appearance: Typically appears as a clear to slightly yellowish liquid or gel.
Solubility: Soluble in water and various solvents used in hair care formulations.
pH: Stable within a range that is compatible with hair and skin, typically between 4.5 and 7.

Production Process

Synthesis: The compound is synthesized through a chemical reaction involving aminopropyl, diglycol, and maleic acid derivatives.
Purification: After synthesis, the compound is purified to remove impurities and ensure its effectiveness and safety.
Formulation: Incorporated into hair care products such as conditioners, masks, and treatments at varying concentrations based on the desired effect.

Applications

Medical: Not typically used in medical applications.

Individuals with sensitive skin or allergies should exercise caution. It is important to ensure that the ingredient is sustainably sourced and free from harmful chemicals.

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.

Waving and straightening agent for hair. It is an ingredient that enables straightening and/or waving by permanently changing the shape or configuration of the keratinous hair fibres.

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.
