Common Name(s): Ppg-2 lauryl ether maleamide,polypropylene glycol-2 lauryl maleamide

DESCRIPTION

What It Does: Provides conditioning benefits in cleansing formulas as a co-surfactant.

Why It's Used: Specialty co-surfactant combining ppg and maleamide functionality for unique conditioning and surfactant interaction properties.

How It Works: Maleamide group provides h-bonding with hair/skin proteins; ppg-2 component adds mild hydrophobicity; lauryl tail provides surfactant anchor.

Typically Found In: Conditioning shampoos,hair treatments,specialty cleansers

SAFETY & COMPATIBILITY

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

Works Well With: Anionic surfactants,amphoteric surfactants,conditioning agents

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Maleamide-functionalized surfactants provide unique surface interactions on protein substrates (hair, skin keratin) via amide hydrogen bonding; ppg modification improves feel and reduces tackiness versus plain lauryl maleamide.
