Description

Methacryloyloxy Hydroxypropyl Maltodextrin/Acrylates Crosspolymer is a synthetic polymer created through a two-step process. First, maltodextrin is modified by reacting it with Glycidyl Methacrylate. The modified maltodextrin is then polymerized with a mixture of Acrylic Acid, Methacrylic Acid or their simple esters, and a crosslinker, Trimethylolpropane Triacrylate. This ingredient is primarily used in cosmetics and personal care products for its thickening, film-forming, and stabilizing properties, enhancing the texture and performance of various formulations.

Chemical Composition and Structure

Methacryloyloxy Hydroxypropyl Maltodextrin/Acrylates Crosspolymer consists of:

Methacryloyloxy Hydroxypropyl Maltodextrin: Maltodextrin modified with Glycidyl Methacrylate to introduce methacryloyloxy groups.
Acrylic Acid and Methacrylic Acid: Acids used in the polymerization process to contribute to the crosslinked structure of the polymer.
Crosslinker (Trimethylolpropane Triacrylate): A chemical agent used to link the polymer chains during polymerization, forming a three-dimensional network.
The structure features a network of methacryloyloxy-modified maltodextrin molecules, polymerized with acrylic and methacrylic acids, and crosslinked with trimethylolpropane triacrylate.

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

Modification of Maltodextrin: Maltodextrin is treated with Glycidyl Methacrylate to introduce methacryloyloxy groups.
Polymerization: The modified maltodextrin is polymerized with a mixture of Acrylic Acid, Methacrylic Acid or their simple esters, and Trimethylolpropane Triacrylate 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 enhances 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 advantageous.
Food: Not typically used in food products, as its primary applications are in cosmetics and personal care.
Industrial Uses: Employed in cosmetic formulations to improve 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.
