Hair, as they are part of key proteins such as collagen and keratin, in addition to being components of the Natural Moisturizing Factor (NMF).
Their strategic incorporation allows formulators to work on the formula from the basic structure of the tissue.
Amino Acids and Their Relationship with the Skin’s NMF
The Natural Moisturizing Factor is composed, in part, of free amino acids that help maintain skin hydration and elasticity.
Among this group, the following stand out:
Serine → Contributes to maintaining skin hydration.
Glycine → Structural amino acid of collagen, key for dermal support.
Proline → Associated with firmness and protein structure.
Glutamic Acid → Applied in hydrating and balancing formulations.
Aspartic Acid → Used in specific developments depending on the cosmetic objective.
These amino acids are incorporated into creams, serums and anti-aging products aimed at reinforcing the skin barrier function.
Application in Hair Repair and Strengthening
The hair fiber is mainly composed of keratin, a protein rich in sulfur-containing and structural amino acids.
Cysteine → Fundamental in keratin structure. Present in repairing treatments and strengthening formulas.
Arginine → Used in shampoos and conditioners for its strengthening function.
Lysine → Applied in developments focused on structural hair support.
Leucine and Valine → Amino acids used in technical formulations related to hair nutrition.
In this context, amino acids help improve fiber strength, elasticity and cohesion.
Advanced Functional Cosmetic Development
Beyond hydration and repair, some amino acids are incorporated into more specialized formulations:
Tryptophan → Used in innovative skincare developments.
Combinations of Serine, Glycine and Proline → Applied in formulas focused on dermal structure.
These types of ingredients are particularly interesting for technical lines or premium cosmetics.
Chelated Derivatives in Cosmetic Formulation
Combining amino acids with minerals allows the development of more stable and well-tolerated forms in formulation.
Zinc Bisglycinate → Used in purifying and sebum-regulating products.
Magnesium Bisglycinate → Applied in specific facial care developments.
These derivatives allow mineral benefits to be integrated into more functional structures within the formula.
A Technical Tool for the Formulator
The incorporation of amino acids in cosmetics is not driven solely by market trends. From a technical perspective, they allow formulators to:
✔ Work on the formula from the protein structure
✔ Reinforce hydration and barrier function
✔ Optimize hair fiber cohesion
✔ Develop more technical and differentiated products
In an environment where cosmetics are evolving toward more functional and scientifically supported formulations, amino acids represent a strategic tool for R&D.
At Corquimia, we supply amino acids and derivatives for cosmetic applications upon technical consultation.
If you are developing a new line or reformulating an existing product, we can advise you according to your specific application.
