Description

Sodium Acrylates/Methacryloyl Maltodextrin Crosspolymer is a synthetic polymer created by cross-linking sodium acrylates and methacryloyl maltodextrin. This ingredient is primarily used in cosmetics and personal care products for its thickening, film-forming, and stabilizing properties. It enhances the texture and performance of various formulations.

Chemical Composition and Structure

Sodium Acrylates/Methacryloyl Maltodextrin Crosspolymer consists of:

Sodium Acrylates: Sodium salts of acrylic acid polymers, which provide thickening and film-forming properties.
Methacryloyl Maltodextrin: A maltodextrin derivative modified with methacryloyl groups, which enhances the polymer's stability and performance.
Crosslinking Agents: Chemicals used to create a network structure by linking sodium acrylates and methacryloyl maltodextrin molecules.
The structure features a cross-linked network of sodium acrylates and methacryloyl maltodextrin, offering improved film-forming and stabilizing properties.

Physical Properties

Appearance: Typically appears as a white or off-white powder.
Odor: Generally neutral.
Solubility: Soluble in water, making it suitable for aqueous formulations.
pH: Generally neutral to slightly acidic, compatible with the skin’s natural pH.
Stability: Maintains stability under standard storage conditions; should be protected from excessive heat and moisture.

Production Process

Preparation of Sodium Acrylates and Methacryloyl Maltodextrin: Sodium acrylates and methacryloyl maltodextrin are synthesized and prepared.
Crosslinking: Sodium acrylates and methacryloyl maltodextrin are treated with crosslinking agents to form a polymer network.
Purification: The resulting polymer is purified to remove unreacted materials and impurities.
Drying and Milling: The purified polymer is dried and milled into a fine powder suitable for use in cosmetic formulations.

Applications

Cosmetics: Used as a thickening agent, film-forming agent, and stabilizer in skincare and cosmetic products. It improves the consistency, texture, and sensory attributes of the products.
Medical: May be utilized in medical and personal care products where thickening and film-forming properties are beneficial.
Food: Not typically used in food products, with its primary applications in cosmetics and personal care.
Industrial Uses: Employed in cosmetic formulations to enhance texture, stability, and performance.

Environmental and Safety Considerations

Generally regarded as safe for topical application, however, like all cross-polymers, it should be used in accordance with established guidelines to avoid potential allergic reactions or skin irritations. It is important to ensure that the ingredient is produced sustainably and is free from harmful contaminants.

INCI Functions:


Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.
