คำถาม

I am comparing three amphoteric surfactants for use in cosmetic formulations: Coco-Foam-50™ (Cocamidopropyl Hydroxysultaine), Laura-Foam-50™ (Lauramidopropyl Hydroxysultaine), and Lauryl Hydroxysultaine.

Could you explain the key differences in their properties, focusing on:

  • Chemical structure (Amidopropyl vs. Alkyl)
  • Fatty chain source and purity (e.g., mixed C8-C18 from Coconut vs. uniform C12)
  • Performance characteristics, such as foam boosting, viscosity building, clarity, and hydrotroping ability?

คำตอบ

The three ingredients—Coco-Foam-50™, Laura-Foam-50™, and Lauryl Hydroxysultaine—are all amphoteric surfactants (hydroxysultaines) known for their mildness, foam-boosting, and viscosity-building properties. The primary differences lie in their chemical structure and the source/purity of their fatty acid chains.

Here is a comparison of their properties:

Feature Coco-Foam-50™ (Cocamidopropyl Hydroxysultaine) Laura-Foam-50™ (Lauramidopropyl Hydroxysultaine) Lauryl Hydroxysultaine
Chemical Structure Amidopropyl derivative Amidopropyl derivative Straight Alkyl derivative
Fatty Chain Source Mixed C8-C18 (primarily C12/C14) derived from Coconut oil Uniform C12 (Lauric acid) Uniform C12 (Lauryl alcohol)
Foam & Viscosity Excellent foam booster and viscosity builder, especially when paired with anionic surfactants (like SLES). Excellent foam booster and viscosity builder. Often offers slightly better clarity and flash foam due to the uniform C12 chain. Good foam and viscosity properties, but generally less potent in viscosity building than the amidopropyl versions.
Key Use General-purpose mild surfactant, often used to replace Cocamidopropyl Betaine for a milder feel. Preferred when a purer, more uniform C12 chain is desired for better clarity and specific foam characteristics. Used for its mildness and excellent hydrotroping properties (solubilizing other ingredients).

Summary of Differences

  1. Structure (Amidopropyl vs. Alkyl): Coco-Foam-50™ and Laura-Foam-50™ are amidopropyl derivatives. This structure is key to their superior performance in building viscosity and stabilizing foam compared to the straight alkyl derivative, Lauryl Hydroxysultaine.
  2. Chain Purity: Laura-Foam-50™ is based on a purer, uniform C12 chain, while Coco-Foam-50™ is based on the mixed chain lengths found in coconut oil. The purer C12 chain of Laura-Foam-50™ can lead to better clarity in the final product.
