Glutamine ●
TL;DR. This ingredient primarily functions as a skin and hair conditioning amino acid, helping support moisture feel and softness in formulas. It can also contribute to humectancy because it is water soluble and compatible with the skin’s natural moisturizing factor profile.
What does Glutamine do in a cosmetic formula?
This ingredient primarily functions as a skin and hair conditioning amino acid, helping support moisture feel and softness in formulas. It can also contribute to humectancy because it is water soluble and compatible with the skin’s natural moisturizing factor profile.
Is Glutamine clean?
From a clean beauty perspective, this ingredient is generally well tolerated, low in sensitization concern, and not a common restricted-list issue. The main quality consideration is standard raw-material purity, especially for fermentation-derived or hydrolyzed sources.
Is Glutamine sustainable?
This ingredient is commonly made by fermentation or protein hydrolysis from plant-derived feedstocks, depending on supplier route. It is readily biodegradable, water soluble, and not expected to persist in the environment.
Is Glutamine COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic frameworks when produced from approved natural-origin feedstocks and allowed processing methods. Its renewable sourcing potential, biodegradability, and mild profile align well with Green Chemistry principles.
How does Glutamine work chemically?
This molecule is a zwitterionic amino acid with a polar amide side chain, which explains its water solubility and compatibility with aqueous skin-care systems. It is typically used at low levels, often around 0.1% to 2%, and is best formulated under mild pH and moderate heat because aqueous solutions can slowly deamidate under harsher conditions.
