Sodium Starch Octenylsuccinate is a modified starch-derived cosmetic ingredient used primarily as an absorbent, emulsion stabilizer, viscosity-controlling agent and texture-modifying ingredient. It is the sodium salt of the reaction product of starch with octenylsuccinic anhydride. The cosmetic ingredient is also known as Sodium Corn Starch Octenylsuccinate.
Sodium Starch Octenylsuccinate combines the functional characteristics of starch with octenylsuccinate modification. This gives it useful formulation properties for cosmetic and personal-care products where oil absorption, texture, viscosity control and emulsion stability are required.
The ingredient is particularly relevant to formulations requiring a dry, smooth or soft sensory profile, controlled viscosity and improved physical stability.
Sodium Starch Octenylsuccinate is a modified starch ester produced by reacting starch with octenylsuccinic anhydride and neutralizing the resulting material with a sodium salt. JECFA describes Starch Sodium Octenylsuccinate as starch esterified with octenylsuccinic anhydride.
The starch component provides the polymeric base, while octenylsuccinate modification changes its functional behavior and makes it useful in formulation systems requiring absorbency, viscosity control and emulsion stabilization.
A key cosmetic function of Sodium Starch Octenylsuccinate is absorbency.
It can help absorb finely dispersed substances and can contribute to a drier, less greasy sensory feel in suitable formulations. COSMILE Europe lists absorbent functionality for this ingredient.
Potential applications include:
Sodium Starch Octenylsuccinate can be used to control formulation viscosity.
It can contribute to the consistency and flow characteristics of suitable cosmetic systems. The actual viscosity effect depends on concentration, formulation composition, processing conditions and the particular grade.
Potential applications include:
COSMILE Europe identifies Sodium Starch Octenylsuccinate as a viscosity-controlling ingredient.
Sodium Starch Octenylsuccinate can support emulsion stabilization by contributing to the physical structure and stability of suitable formulations.
It can be considered for:
The final stabilization performance depends on the complete formulation, emulsifier system, oil phase, water phase and processing conditions.
Sodium Starch Octenylsuccinate can contribute to the texture and sensory properties of cosmetic products.
It may help provide:
This makes it useful for cosmetic products where sensory performance is an important formulation consideration.
Sodium Starch Octenylsuccinate can be evaluated in suitable skin-care products where absorbency, texture modification and emulsion stabilization are required.
Potential applications include:
Sodium Starch Octenylsuccinate can be used in selected color cosmetic formulations where absorbency and texture control are desirable.
Potential applications include:
Its absorbent functionality can be particularly relevant where formulators want to modify the sensory profile of a finished cosmetic product.
Sodium Starch Octenylsuccinate can be incorporated into suitable creams and lotions to support texture, absorbency and physical stability.
Potential formulation benefits include:
The ingredient can also be considered for powder-based cosmetic systems.
Its absorbent and texture-modifying characteristics can be useful in:
The actual performance depends on the particle characteristics and formulation composition.
Sodium Starch Octenylsuccinate is defined as the sodium salt of the reaction product of octenylsuccinic anhydride with starch, with Zea Mays (corn) starch identified in the cosmetic ingredient definition by the Korean Cosmetic Association.
It is a modified polymeric starch rather than a single low-molecular-weight compound. Therefore, its exact molecular characteristics can vary according to the starch source, modification level and manufacturing process.
Sodium Starch Octenylsuccinate is generally supplied as a white or nearly white powder or granules. If pregelatinized, it may also occur as flakes, amorphous powder or coarse particles.
Typical quality-control parameters may include:
JECFA specifications state that octenylsuccinate groups should be not more than 3.0% on a dried basis and residual free octenylsuccinic acid not more than 0.3% on a dried basis for the specified material.
The hydration and solubility behavior depends on whether the material is native-granule or pregelatinized and on the particular grade.
JECFA describes non-pregelatinized starch sodium octenylsuccinate as insoluble in cold water, with typical colloidal and viscous behavior in hot water; it is also described as insoluble in ethanol.
Therefore, the exact processing and grade should be considered when developing a formulation.
Important formulation parameters include:
The actual performance should be confirmed using the specific commercial grade intended for the finished product.
