ETHYL ARGINATE HCL.

Valuable CAS 36589-29-4 / HAIR CONDITIONING

Ethyl Arginate HCl is a multifaceted cationic surfactant recognized for its broad-spectrum antimicrobial properties. It effectively functions as both a preservative and an active ingredient, addressing concerns such as acne, dandruff, and body odor, while also offering conditioning benefits to skin and hair.

Science

Mechanism of Action

This ingredient operates as a 'membrane-active agent,' utilizing its cationic charge to adsorb onto the negatively charged cellular membranes of bacteria and fungi. This interaction disrupts the structural integrity of the microbial membranes, leading to the leakage of vital cytoplasmic material, compromised metabolic processes, and ultimately, inhibition of microbial proliferation.

Key findings

  1. 01 Studies indicate an antiseptic effect and reduced irritation in formulations at concentrations ranging from 0.05% to 0.3%.
  2. 02 As an active cosmetic ingredient, concentrations up to 0.8% have been approved for use in soaps, anti-dandruff shampoos, and deodorants (non-spray). In anti-dandruff applications, it shows comparable or superior performance to traditional active agents. In anti-acne gels, it demonstrates a quicker killing effect and a notable 13.5% decrease in sebum production.

Stability

Ethyl Arginate HCl maintains optimal stability within a pH range of 3.0 to 8.0. However, its stability decreases with increasing temperature and at pH levels below the optimal range. Strong inorganic acids have a more pronounced impact on stability than organic acids. Its half-life exceeds one year at pH 4, reduces to 57 days at pH 7, and further accelerates to 34 hours at pH 9 (at 25°C), indicating increased hydrolysis in alkaline conditions. While resistant to conventional heating (≤ 80°C), prolonged exposure to temperatures above 80°C for more than 30 minutes should be avoided.

Sensitization risk Unknown

The SCCS considers Ethyl Arginate HCl safe as a preservative up to a maximum concentration of 0.15% in mouthwashes (not for children under 10 years of age), but did not assess its safety in toothpaste. It is approved in the EU as a cosmetic preservative up to 0.4% (excluding lip, oral, and spray products). As an active cosmetic ingredient, it is approved up to 0.8% in soaps, anti-dandruff shampoos, and non-spray deodorants. The FDA has approved it as Generally Recognized As Safe (GRAS) for use as an antimicrobial in specific food categories at levels up to 0.02%. While generally well-tolerated, high concentrations can cause mild irritation, necessitating careful formulation.
