Sodium Hydrolyzed Potato Starch Dodecenylsuccinate is the sodium salt derived from the reaction of dextrin with dodecenylsuccinic anhydride. This ingredient is primarily used in cosmetic formulations as a thickening agent, foam boosting, and cleansing agent, enhancing the texture and stability of products while providing moisturizing benefits.
Chemical Composition and Structure
The chemical composition of Sodium Hydrolyzed Potato Starch Dodecenylsuccinate includes:
- Dextrin: A hydrolyzed starch that serves as the base for the reaction, providing functional properties.
- Dodecenylsuccinic Anhydride: A modified fatty acid that reacts with dextrin to create a compound with emulsifying and thickening properties.
Physical Properties
- Appearance: Typically a white to off-white powder or granule.
- Solubility: Soluble in water, allowing for easy incorporation into aqueous formulations.
- pH: Generally neutral, around 6-7.
- Odor: Mild, characteristic of plant-derived ingredients.
- Stability: Stable under normal storage conditions but should be protected from extreme temperatures.
Production Process
- Reaction: Sodium Hydrolyzed Potato Starch Dodecenylsuccinate is produced by reacting dextrin with dodecenylsuccinic anhydride in a controlled environment to form the sodium salt.
- Purification: The resulting product is purified to remove any unreacted materials and impurities.
- Formulation: The purified compound is incorporated into cosmetic products, often combined with other ingredients to enhance performance.
Applications
- Cosmetics: Commonly included in creams, lotions, and hair care products for its thickening, emulsifying, and moisturizing effects.
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.
Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
Environmental and Safety Considerations
Sodium Hydrolyzed Potato Starch Dodecenylsuccinate is generally regarded as safe for topical application in cosmetics when used according to recommended guidelines. It is well-tolerated by most skin types, but individuals with sensitivities to starches or modified fatty acids should exercise caution.
Responsible sourcing and production practices are essential to ensure that the ingredient is free from harmful contaminants and produced sustainably.
