Corn Starch/Maltodextrin Crosspolymer is a modified starch compound created through the cross-linking of corn starch and maltodextrin. This ingredient is primarily used in cosmetics and personal care products for its textural properties, film-forming capabilities, and stabilizing effects. It enhances the sensory attributes and performance of various formulations.

Chemical Composition and Structure

Corn Starch/Maltodextrin Crosspolymer includes:

Corn Starch: A carbohydrate derived from corn, which serves as the base for the polymer.
Maltodextrin: A carbohydrate resulting from the partial hydrolysis of starch, which modifies the properties of the starch.
Crosslinking Agents: Chemical agents used to link corn starch and maltodextrin molecules, forming a three-dimensional network.
The structure features a network of cross-linked corn starch and maltodextrin molecules, providing enhanced film-forming and stabilizing properties.

Physical Properties

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

Production Process

Preparation of Corn Starch and Maltodextrin: Derived from corn through hydrolysis and processing.
Crosslinking: The starch and maltodextrin are treated with crosslinking agents to create the polymer network.
Purification: The crosspolymer is purified to remove any unreacted components and impurities.
Drying and Milling: The purified product is dried and milled into a fine powder for use in cosmetic formulations.

Applications

Cosmetics: Functions as a film-forming agent, texture enhancer, and stabilizer in skincare and cosmetic products. It improves the consistency, spreadability, and sensory experience of the products.
Medical: Can be used in medical and personal care products where film-forming and stabilizing properties are advantageous.
Food: Not typically utilized in food products, with its primary applications in cosmetics and personal care.
Industrial Uses: Employed in cosmetics 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 according to established guidelines to avoid potential allergic reactions or skin irritations. It is important to ensure that the ingredient is sustainably sourced and free from harmful contaminants.

INCI Functions:


Film-forming agent. It produces, upon application, a very thin continuous film with an optimal balance of cohesion, adhesion and stickiness on skin, hair or nails to counteract or limit damage from external phenomena such as chemicals, UV rays and pollution.
