Description

Hydrolyzed Corn Starch Octenylsuccinate is a derivative of corn starch that has been chemically modified through hydrolysis and esterification with octenylsuccinate. This ingredient is primarily used in cosmetics and personal care products for its film-forming, stabilizing, and texture-enhancing properties. It helps to improve the feel and performance of formulations.

Chemical Composition and Structure

Hydrolyzed Corn Starch Octenylsuccinate contains several key components:

Hydrolyzed Corn Starch: Corn starch that has undergone partial hydrolysis, breaking down the starch molecules into smaller, more manageable sizes. This modification enhances the starch's functionality in cosmetic formulations.
Octenylsuccinate: An ester formed by the reaction of octene and succinic anhydride. This component is responsible for the film-forming properties and helps in stabilizing emulsions.
The chemical structure of Hydrolyzed Corn Starch Octenylsuccinate features a starch backbone modified with octenylsuccinate groups, which confer unique properties such as improved spreadability and stability.

Physical Properties

Appearance: Typically appears as a white or off-white powder.
Odor: Generally has a neutral odor.
Solubility: Partially soluble in water and oil, making it versatile for various formulations.
pH: Generally neutral to slightly acidic, compatible with the skin's natural pH.
Stability: Maintains stability in a range of conditions; should be stored away from excessive heat and moisture to preserve its properties.

Production Process

Corn Starch Preparation: Corn starch is first prepared from corn kernels.
Hydrolysis: The starch is hydrolyzed to break down its larger molecules into smaller fragments.
Esterification: The hydrolyzed starch is reacted with octenylsuccinate to form the modified starch.
Purification: The resulting product is purified to remove any unreacted materials and impurities.
Drying and Milling: The purified product is dried and milled into a fine powder suitable for use in cosmetic formulations.

Applications

Cosmetics: Used as a film-forming agent, stabilizer, and texture enhancer in skincare and cosmetic products. It helps to improve the product's consistency, spreadability, and overall sensory experience.
Medical: May be utilized in medical and personal care products where film-forming and stabilizing properties are beneficial.
Food: Not commonly used in food products, as its primary applications are 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 chemical additives, 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:


Absorbent. Absorbs substances dispersed or dissolved in aqueous solutions, water/oil, oil/water.

Binder agent. Ingredient that is used in cosmetic, food and pharmaceutical products as an anti-caking agent with the function of making the product in which it is incorporated silky, compact and homogenous. The binder, either natural such as mucilage, gums and starches or chemical, may be in the form of a powder or liquid.

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.
