CAPRYLOYL QUINOA AMINO ACIDS.

Valuable CAS 226993-80-2 / HAIR CONDITIONING, SKIN CONDITIONING

A sophisticated lipoamino acid surfactant derived from quinoa proteins and caprylic acid that provides ultra-gentle cleansing. Unlike traditional sulfates, it maintains the skin's structural integrity while delivering secondary hydrating benefits through its natural amino acid profile.

Summary

Mild surfactant Cleansing agent Skin conditioning Foam booster

Science

Mechanism of Action

As an acylated amino acid, it functions as a mild anionic surfactant that lowers surface tension to emulsify sebum and impurities without disrupting the lipid bilayer. Once applied, skin-resident amidase enzymes can metabolize the molecule into caprylic acid and quinoa amino acids, which reinforce the skin's Natural Moisturizing Factor (NMF) and provide conditioning benefits.

Key findings

  1. 01 A 5% concentration demonstrated significantly lower protein denaturation in Zein tests compared to SLES, indicating superior skin compatibility.
  2. 02 In-vivo barrier studies at 2% show a reduction in transepidermal water loss (TEWL) and enhanced preservation of the skin barrier when integrated into surfactant systems.
  3. 03 Ross-Miles foam testing at 1% confirmed the production of stable, fine-textured foam (160mm) even in hard water conditions.

Due to its premium 'superfood' marketing appeal, this ingredient is frequently included at trace amounts (<0.5%) for label claims. However, clinical benefits for barrier protection and foaming performance require a minimum concentration of 1-2%.

Stability

Highly stable across a broad pH range of 4.0 to 9.0. It maintains excellent foaming capacity even in the presence of sebum or hard water.

Synergies

  • Sodium Laureth Sulfate (reduces overall system irritancy)
  • Glycerin
  • Mild non-ionic surfactants

Conflicts

  • Cationic surfactants
  • Cationic polymers (at high concentrations)
  • Environments with pH below 3.5 (may cause precipitation)
