​Main types

Cosmetic grade sodium hyaluronate main molecular weight:

1.5*10⁶Da-2.5*10⁶Da (1.5MDa-2.5MDa)

1.3*10⁶DaDa-1.5*10⁶Da (1.3MDa-1.5MDa)

5*10⁵Da-1.5*10⁶Da (0.5MDa-1.5MDa)

1*10⁵Da-5*10⁵Da

<1*10⁵Da

<1,000Da

sodium hyaluronate (HA) is divided into high molecular weight hyaluronic acid (HMHA, molecular weight greater than 2*10⁶Daa) and low molecular weight

Hyaluronic acid (LMHA, molecular weight 5*10³Da~9*10⁵Da) based on their different molecular weights.

sodium hyaluronate with low molecular weight (LMHA) is better penetration and absorption.

sodium hyaluronate with high molecular weight (HMHA) has stronger film-forming and viscoelastic support.

Use

sodium hyaluronate is a natural moisturizing agent in skin care products.

Except cosmetic use, sodium hyaluronate has pharmaceutical grade and food grade.
