Amino acids

Amino acids are organic compounds produced from the amine and carboxylic acid functional group. The key elements of amino acids are carbon, oxygen, nitrogen, and hydrogen. About 500 amino acids can be classified in six main ways: aliphatic, hydroxic, aromatic, basic, and acidic, plus their amide. Further, other non-protein amino acids act as metabolic intermediates.

Amino acids are useful not only in human nutrition but also in the cosmetic industry. In human nutrition, amino acids are used to synthesize proteins and additional biomolecules; thus, they are found in the human body. These compounds are the building blocks our organism uses to build its proteins, enzymes, and peptides. 

Famous skin proteins collagen, elastin, and keratin are also made of amino acids. In addition, they are oxidized to urea and carbon dioxide to generate energy.

However, amino acids' function is not limited to building dermal proteins. They are also involved in regulating a large number of processes associated with skin healing, moisture retention (NMFs), and protection from UV irradiation. Due to their comprehensive beneficial features, safety, and insensibility, amino acids are common ingredients in many beauty concoctions.

Moreover, many amino acid derivatives are used as gentle detergents in cleansing applications or serve as emollients, antioxidants, chelating agents, etc.

Potassium Olivoyl PCA is a vegetal softening lipo-amino acid as a fatty acid vehicle an emollient, and moisturizing agent, and a softening surfactant.

Proline
Proline is the main building block of dermal collagen. Due to its significant role in skin structure maintenance and easy absorbance proline is a prominent ingredient of anti-aging skin care formulations.  
Sarcosine
Sarcosine (N-methyl glycine) is a natural amino acid found in human body tissues and ubiquitous in raw food such as egg yolks, meat, vegetables, and legume seeds.

Sepicalm™ S is a lipo-aminoacid-based complex enriched minerals and vectorized essential amino acids for all-around protection against stress, a genuine feeling of well-being, and skin comfort.

Serine
Serine is a small-molecule nonessential amino acid, the precursor of Glycine, thus involved in the synthesis of collagen. It also a part of essential NMFs (natural moisturizing factors) preventing transepidermal water loss.
Silk

Silk Amino Acids is a mixture obtained from pure silk fibers by hydrolysis to their free amino acids under carefully controlled conditions. The principal amino acids in this ingredient are glycine, alanine, and serine.

Sodium Cocoyl Alaninate

Sodium Cocoyl Alaninate is an amino acid-based weakly acidic detergent derived from alanine and natural fatty acids. It is typically used in hair and body cleansing applications. It can be used as a foam booster when combined with other surfactants.
