Lauramidopropyl Betaine\ ●
TL;DR. This ingredient is a mild zwitterionic surfactant used for cleansing, foam boosting, and reducing the harsh feel of anionic surfactant systems. It also helps thicken rinse-off formulas when paired with salts and sulfate or sulfonate surfactants.
What does Lauramidopropyl Betaine\ do in a cosmetic formula?
This ingredient is a mild zwitterionic surfactant used for cleansing, foam boosting, and reducing the harsh feel of anionic surfactant systems. It also helps thicken rinse-off formulas when paired with salts and sulfate or sulfonate surfactants.
Is Lauramidopropyl Betaine\ clean?
It is generally accepted in many clean frameworks, but it carries caveats around residual amidoamine and tertiary amine impurities that can trigger irritation or sensitization in susceptible users. High-purity grades with tight impurity controls are the cleaner benchmark.
Is Lauramidopropyl Betaine\ sustainable?
This material is typically made from coconut or palm-derived fatty acids plus synthetic amine chemistry, so sourcing transparency and palm certification matter. It is expected to be readily biodegradable, with low persistence compared with silicone or fluorinated materials.
Is Lauramidopropyl Betaine\ COSMOS-approved?
It can be permitted in COSMOS-natural formulations when made from allowed feedstocks and processes, but it is not a simple minimally processed organic ingredient. Its Green Chemistry profile is mixed: renewable fatty feedstock and biodegradability are positives, while petrochemical amine inputs and impurity control are the tradeoffs.
How does Lauramidopropyl Betaine\ work chemically?
The molecule has a C12 fatty amide tail linked to a propyl zwitterionic head, giving compatibility with anionic, nonionic, and cationic systems. It is commonly used around 2 to 10% active in rinse-off products, is stable across roughly pH 4 to 8, and formulation quality depends on controlling residual amidoamine, tertiary amine, and salt content.
