We are global producer of hyaluronan

Extraordinary hyaluronic acid

This unbranched polysaccharide have different biological effects which depend on its molecular weight. It is a natural component of the human body. It is located in the extracellular matrix, it can be found in the eyes, and also in the articular ligaments.

We prefer cleaner producing path

Contipro prefers a path of biotechnological production, when hyaluronic acid is extracted from the cell walls of the bacteria Streptococcus zooepidemicus. It is a costlier way but this path is offset by quality and ethical thoughtfulness.

What si the difference between

People are often confused what is the difference between hyaluronic acid (HA) and sodium hyaluronate (SHA). Indeed, if you try to google the term “hyaluronic acid vs. sodium hyaluronate”, you will find various types of articles and discussions demonstrating it is still a hot topic. We took just the first top 10 hits obtained by google search (9 of them in the field of beauty industry) and went through them. We found mistakes or misleading information in ALL of them.

Claims obtained from the first ten websites after typing search term “hyaluronic acid vs. sodium hyaluronate”:

Claim 1: Hyaluronic acid x sodium hyaluronate in nature and human body?

Hyaluronic acid, also called hyaluronan, is a polysaccharide, nonsulfated glycosaminoglycan. Nowadays, the name hyaluronan is used more prevalently because the polysaccharide is present in nature in a salt form, not an acid. The salt consists of anion hyaluronan and a cation (sodium, potassium, calcium etc.). Hyaluronic acid itself also exists, but mostly in chemical laboratories because it undergoes fast degradation and its solution is very acidic. For these reasons, under physiological conditions, you will not find hyaluronic acid in living organisms. Organic chemists sometimes use hyaluronic acid form, because it is soluble in some organic solvents which is an advantage for certain types of chemical reactions e.g. for preparation of some hyaluronic acid derivatives. However, chemists prepare hyaluronic acid by themselves from its salts e.g. by using ion exchangers which exchange sodium cations for hydrogen cations and use it immediately to prevent its degradation. Both the hyaluronic acid as well as sodium hyaluronate are soluble in water where they dissociate to the same anion so finally it is completely the same molecule you find in cosmetic products.

Claim 2: Hyaluronic acid x sodium hyaluronate on the market

Due to the stability problems and because manufacturers use organisms as a source of sodium hyaluronate (certain species of microorganisms, rooster combs, bovine vitreous humor etc.), you will not find hyaluronic acid available on the market, only its salts. The name hyaluronic acid is used as a synonym for a salt there. In cosmetic field, the INCI name Hyaluronic acid exists, but it is just a synonym for a salt as well. It refers to sodium hyaluronate which is the most common type of hyaluronic acid salt sold. Another available salts of hyaluronic acid are potassium hyaluronate with the same INCI name or calcium hyaluronate with no INCI name for instance. Sodium hyaluronate of lower molecular weights has an INCI name Hydrolyzed hyaluronic acid.

Claim 3: Sodium hyaluronate has a smaller molecular size than hyaluronic acid

There is NO difference in molecular weight between hyaluronic acid and sodium hyaluronate. You can have both molecules in a wide range of molecular weights theoretically. However, hyaluronic acid itself is not stable and easily degrades so it is complicated to prepare hyaluronic acid of high molecular weight.

Claim 4: Hyaluronic acid cannot be absorbed when applied topically, it can only be injected, whereas sodium hyaluronate penetrates skin

Hyaluronic acid is not available on the market, only salts, most commonly sodium hyaluronate. Penetration of sodium hyaluronate depends on its molecular weight. High molecular weight sodium hyaluronate is a very big molecule which does not penetrate the skin whereas the lower MW, the better penetration. A few studies are already available in the scientific literature to support this phenomenon.

Claim 5: Sodium hyaluronate is created by scientists to increase stability of hyaluronic acid and lessens the likelihood of its oxidization

This is partly true, sodium hyaluronate is indeed more stable than hyaluronic acid, but it is always produced in a form of salt by organisms so there is no need to “create” it by scientists. Oppositely, hyaluronic acid is “created” by chemists from its salts.

Claim 6: Sodium hyaluronate is obtained through the chemical reaction between hyaluronic acid and sodium hydroxide

Sodium hyaluronate is produced by animals/microorganisms as the final desired product, no further chemical reactions are needed. The product must be only isolated from the organisms using various kinds of techniques including filtrations, precipitations, washing etc.

Conclusion: hyaluronic acid vs. sodium hyaluronate

The names hyaluronic acid and sodium hyaluronate are used interchangeably as synonyms referring to sodium hyaluronate and therefore there is no difference in their physical, chemical or biological properties.
