Common Name(s): Bis-octenylsuccinoyloxypropyl dimethicone,octenylsuccinate dimethicone

DESCRIPTION

What It Does: Creates a silky, smooth feel on skin and hair while providing conditioning and light film coverage.

Why It's Used: Selected for its unique combination of silicone sensory properties with octenylsuccinate ester functionality, enabling good substantivity to skin and hair.

How It Works: Succinyl ester groups increase substantivity to skin/hair versus plain dimethicone; octenyl chain provides gentle hydrophobic film character; overall molecule behaves as a conditioning emollient with improved retention.

Typically Found In: Hair conditioners,silky body lotions,skin serums,leave-in hair treatments

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low

Sensitivity Concerns: Generally well tolerated. silicone-derived; inert.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. ewg score: 1–2.

Works Well With: Dimethicone,cyclomethicone,emollients,conditioning agents

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Octenylsuccinate modification of silicones increases polar interactions with skin and hair keratin; the bifunctional design (lipophilic octenyl tail + silicone backbone + ester linkage) provides superior film formation compared to unmodified dimethicone.
