What is Sodium Acetylated Hyaluronate?

Hyaluronic acid (HA), also known as hyaluronic acid, is composed of (1-3)-2-N-acetylamino-2-deoxy-D-glucose-(1-4)-O-β-D-glucose It is an acidic straight-chain polymucopolysaccharide formed by the repeated arrangement of the disaccharide of uronic acid. It has strong hydrophilicity and very good moisturizing properties. It is widely present in the cytoplasm of animal tissue cells and the membrane of some bacteria. In medicine, cosmetics and food, it is also recognized as the most ideal natural moisturizing factor by the international cosmetics industry.

With the continuous improvement of life, the quality of products required in life is rising, and there is no doubt about the moisturizing properties of HA. But the moisturizing time is not so ideal. In a high-paced life, it is impossible for people to touch up makeup and moisturize the skin frequently. So Sodium Acetylated Hyaluronate can solve this problem. Sodium Acetylated Hyaluronate not only has good hydrophilicity, but also has good lipophilic effect. Sodium Acetylated Hyaluronate exists in the skin in the form of a semi-mosaic structure, and the lipophilic section is attached to the epidermis section, which can be firmly attached to the skin due to its lipophilicity. At the same time, acetylated HA with small molecular weight can act on the human epidermis, and has a significant effect on skin moisturizing, skin repairing and increasing skin elasticity.

Sodium Acetylated Hyaluronate Efficacy and Action

Sodium Acetylated Hyaluronate is an acidic mucopolysaccharide that naturally exists in the corneal epidermis and can absorb 1,000 times its own weight in water to achieve skin moisture retention, prevention of water loss through the epidermis, and barrier repair when the skin is damaged. After use, the skin will certainly not feel completely dry and rise radiance. It can boost skin nutrition metabolic rate, make skin soft, smooth, wrinkle-free, boost flexibility, prevent aging, and is an excellent transdermal absorption booster while hydrating. Made use of in conjunction with various other nutrients, it can play a much more optimal result of promoting nutrition absorption.

 

Preparation Method of Sodium Acetylated Hyaluronate

A prep work technique of Salt Acetylated Hyaluronate, making up the complying with steps:
( 1) hyaluronic acid or its salt in acetic acid and acetic anhydride blended solvent, carry out acylation response under the catalysis of vitriol oil;
( 2) after the reaction is ended up, the response fluid is added into water for precipitation, the coarse precipitation is collected, as well as the acetylated hyaluronic acid is obtained after washing with water;

( 3) The pH worth of the acetylated hyaluronic acid in step (2) is adapted to be nearly neutral with alkaline remedy, as well as after being diluted with water, filteringed system and also spray-dried to get the acetylated salt hyaluronate.

Wherein, the hyaluronic acid salt is sodium salt, potassium salt, magnesium salt, calcium salt, zinc salt or ammonium salt of hyaluronic acid, and the molecular weight is 50-3000kDa.

Wherein, the proportion of acetic acid as well as acetic anhydride blended solvent in the blended solvent in the described action (1) is 1:1 ~ 4(v/v); the proportion of hyaluronic acid or its salt to the blended solvent is 1:10 ~ 50 (w/v); the quantity of concentrated sulfuric acid made use of make up 1% to 5% of the complete quantity of the reaction solution.

Wherein, the acylation response temperature of the step (1) is 5-40 ° C., and also the response is finished when the response solution is transparent.

Wherein, the amount of water made use of in the precipitation as well as washing in step (2) is respectively 2 to 20 times the complete quantity of the reaction solution.

Wherein, in step (3 ), the lye service is a remedy consisting of salt hydroxide, sodium carbonate, sodium bicarbonate, sodium phosphate or disodium hydrogen phosphate, and the changed pH worth is 4-8, preferably 5-7.

Wherein, symphonious (3 ), the proportion of the total volume of the Sodium Acetylated Hyaluronate remedy to the hyaluronic acid or its salt after being weakened with water is 5-50 mL:1 g.

Wherein, symphonious (3 ), the inlet air temperature of the spray drying out devices is 100-200 ° C, and the outlet air temperature is 70-120 ° C.

The Sodium Acetylated Hyaluronate prepared by the above technique has an average replacement level of acetyl team of 2.5 to 3.7, preferably 2.8 to 3.5, ideally 2.9 to 3.4, a lot more ideally 3.0 to 3.3; inherent viscosity is 0.1 to 2.3 dL/g, preferably 0.3 to 1.5 dL/g, more ideally 0.5 to 1.2 dL/g. Extensively utilized in the preparation of medications, cosmetics, clinical materials and feed ingredients.

Preparation Method of High Degree of Substitution Sodium Acetylated Hyaluronate

At present, the acetylation reaction is also described in detail in various textbooks. Among them, the active methylene compound is C-acylated at the α-position, and a strong base or strong acid is often used as a catalyst, and then reacted with an acylating agent, and acid chloride and acid anhydride are commonly used. As acylating reagents, carboxylic acids, acyl imidazoles, etc. are also used.

The invention discloses a preparation method of acetylated sodium hyaluronate with high substitution degree, which is characterized in that hyaluronic acid is prepared through I activation separation, II dehydration reaction and III acylation reaction, and I activation separation adopts triethylamine Ⅱ dehydration reaction is carried out with acetic anhydride under low temperature conditions with cobalt 60 radiation-assisted dehydration; described Ⅲ acylation reaction is carried out with catalyst and acylation enhancer; the beneficial effects of the present invention are: Ⅰ activation separation operation improves The degree of acetylation is improved, and the introduction of impurities is reduced while activating; low temperature and cobalt 60 radiation are used to assist dehydration to reduce the dehydration reaction temperature, and acetic anhydride is used as a dehydrating agent, and the material generated after acetic anhydride absorbs water can participate in the subsequent process. In the acylation reaction of III, the introduction of impurities is reduced, and acetic anhydride avoids the environmental pollution caused by acid gas when adding materials in the subsequent process; the catalyst and enhancer are added to the acylation reaction of III, which greatly improves the degree of acetylation.
