Question

What are amino acid-based cleansing ingredients?

  • What are their key properties and benefits, especially regarding gentleness, pH (around 5-6), lather, and easy rinsing without dryness?
  • Could you provide examples of specific amino acid-based cleansing ingredients, such as Sodium Lauroyl Glutamate (AminoWash™), Sodium Cocoyl Isethionate (BabyFoam™), Sodium Cocoyl Glycinate, Sodium Lauroyl Glycinate, Potassium Myristoyl Glutamate, and Potassium Cocoyl Glycinate?
  • What different product formats (e.g., liquid cleansers, powder cleansers like Amino Powder Cleanser, and solid soap bars such as Clear Soap Bar (Amino Acids Based, pH 5-6, Soap-Free)) can these ingredients be used in?
  • Are there any specific formulation considerations or tips when using these ingredients, such as including 0.1% Disodium EDTA with Sodium Lauroyl Glutamate (AminoWash™) to help prevent solidification or precipitation?

Answer

Gentle Cleansing with Amino Acid-Based Ingredients

Amino acid-based cleansing ingredients are known for their exceptional gentleness, making them ideal for sensitive skin and baby products. They provide effective cleaning while being mild and non-irritating.

These ingredients often have a skin-friendly pH (around 5-6) and produce a pleasant, creamy lather that is easy to rinse off without leaving the skin feeling dry.

Some examples of amino acid-based cleansing ingredients include:

  • Sodium Lauroyl Glutamate (AminoWash™): Derived from amino acids and natural fatty acids, this ingredient is very gentle and provides good foaming with a delicate, creamy texture. It's suitable for facial cleansers and can be used in no-tears formulas.
  • Sodium Cocoyl Isethionate (BabyFoam™): Often used in combination with other amino acid-based surfactants, it helps create a good foam texture, particularly in powder formulations like Amino Powder Cleanser.
  • Sodium Cocoyl Glycinate: An amino acid-derived detergent that offers moisturizing properties and generates a good amount of lather.
  • Sodium Lauroyl Glycinate: A highly gentle amino acid-based detergent that provides good lather.
  • Potassium Myristoyl Glutamate: Another highly gentle amino acid-based detergent known for providing good lather.
  • Potassium Cocoyl Glycinate: A highly concentrated, gentle amino acid-derived detergent with good foaming capabilities.

These ingredients can be used in various cleansing product formats, including liquid cleansers, powder cleansers like Amino Powder Cleanser, and even solid soap bars such as the Clear Soap Bar (Amino Acids Based, pH 5-6, Soap-Free).

When formulating with Sodium Lauroyl Glutamate (AminoWash™), it is recommended to include 0.1% Disodium EDTA to help prevent solidification or precipitation.
