Common Name(s): Isopropyl c12-15-pareth-9 carboxylate,isopropyl peg-9 lauryl/myristyl carboxylate

DESCRIPTION

What It Does: Helps oil and water blend with mild anionic surfactant activity.

Why It's Used: Isopropyl ester of the carboxylate of peg-9 c12-15 fatty alcohol; the isopropyl ester provides lipophilic character while the ether-carboxylate gives mild anionic character.

How It Works: Peg-9 chain provides hydrophilicity; c12-15 fatty tail provides lipophilic anchoring; carboxylate provides mild anionic emulsification; isopropyl ester modification adds lipophilic character.

Typically Found In: Mild anionic emulsion systems,surfactant blends

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low

Sensitivity Concerns: Generally well tolerated.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

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

Works Well With: Nonionic surfactants,other mild anionics

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Ether-carboxylate surfactants (pareth carboxylates) are mild anionic surfactants less irritating than ether sulfates; the isopropyl ester modification in this ingredient adds lipophilicity enabling use as an emulsifier.
