product description

SODIUM ACETYLATED HYALURONATE

  1. Introduction

 

INCI name: SODIUM ACETYLATED HYALURONATE

Sodium acetylated hyaluronate (AcHA) is a derivative of sodium hyaluronate (HA), which is prepared by acetylation of sodium hyaluronate (HA). It is both hydrophilicity and lipophilicity.

 

Sodium acetylated hyaluronate has the advantages of high skin affinity, efficient and lasting moisturizing, softening stratum corneum, strong skin softening, enhancing skin elasticity, improving skin roughness,etc. It is refreshing and non-greasy, and can be widely used in cosmetics such as lotion, mask and essence.

 

   Molecular formula:

                              

 

  1. Function

High skin affinity

AcHA's hydrophilic and fat-friendly nature gives it a special affinity with the skin's cuticles

The high skin affinity of AcHA makes it more evenly and closely adsorbed on the surface of the skin, even after rinsing with water.

 

HA and AcHA act on the surface of the skin, as following:

 

                                                   

Strong moisture retention

AcHA can firmly adhere to the surface of the skin, reduce the loss of water on the surface of the skin, and increase the content of moisture of skin. It also can quickly penetrate into the stratum corneum, combine with the water in the stratum corneum, and hydrate to soften the stratum corneum. AcHA internal and external synergistic effect, play an efficient and lasting moisturizing effect, increase skin water content, improve skin rough, dry state, make skin full and moist.

                                ▶ Bound water in stratum corneum mg/100mg of dry tissue

                                 

The water binding capacity of AcHA in stratum corneum is about 2 times that of HA, indicating that the moisture retention capacity of AcHA is much higher than that of ordinary HA.

                                                      Skin surface water retention capacity

                                      

   

Compared with the use of HA aqueous solution, the use of AcHA aqueous solution can make the skin surface water retention capacity higher and longer lasting. Shows that AcHA has good skin water retention ability.

 

Stratum corneum-softening

AcHA has a special affinity to the stratum corneum, which can stay on the surface of the stratum corneum and produce a special and lasting softening effect of the stratum corneum, thus increasing the elasticity of the skin.
