ES Sodium hyaluronate powder is the solid powder form of sodium hyaluronate. It is a solid product made from liquid or gel sodium hyaluronate through purification, drying and other processes. It is essentially a product of the physical transformation of sodium hyaluronate, and its chemical structure is consistent with that of liquid sodium hyaluronate. cas number 9067-32-7 and it is mostly white or off-white amorphous powder in appearance, with strong water solubility. It can quickly dissolve and restore its moisturizing activity when exposed to water. It retains the core characteristics of sodium hyaluronate, with only morphological changes to adapt to different application scenarios.
The core features of sodium hyaluronate powder are high purity, stable form, strong water solubility, and wide adaptability to various scenarios. It is a functional raw material that combines practicality and flexibility.
Core features of sodium hyaluronate powder:
- Sodium hyaluronate powder has excellent purity and low impurity content, which can retain the core activities of sodium hyaluronate such as moisturizing and repairing to the greatest extent.
- Hyaluronic acid sodium salt powder has a stable form, presenting as a white amorphous powder, is not prone to oxidation and deterioration, and is more convenient for storage and transportation.
- Sodium hyaluronate powder has extremely strong water solubility. After coming into contact with water, it dissolves rapidly without precipitation and can be easily mixed into water solutions of different concentrations.
- The proportioning is flexible, allowing for precise control of the addition amount according to demand, and is suitable for different production needs ranging from skin care products to medical products.
- The functions are fully retained. Regardless of the molecular weight (LMW/MMW/HMW), the powder form does not change its core functions (moisturizing, repairing, locking in moisture, etc.).
Now let’s take a detailed look at this product, sodium hyaluronate powder, from different molecular weights.
What are the differences between Sodium hyaluronate powder LMW/MMW/HMW?
The core difference among the three lies in their molecular weights, which leads to significant variations in penetration power, action levels, skin feel and application scenarios. Essentially, they are different “functional versions” of the same ingredient.
The core difference: Molecular weight definition
Sodium hyaluronate powder LMW (low molecular weight) : The molecular weight is usually 10kDa-100kDa, which is the smallest among the three.
Sodium hyaluronate powder MMW (medium molecular weight) : The molecular weight is generally 100kDa-500kDa, which is in the middle range.
Sodium hyaluronate powder HMW (high molecular weight) : Its molecular weight is mostly above 500kDa, making it the largest among the three.
Key performance differences
| Dimension | Sodium hyaluronate powder LMW | Sodium hyaluronate powder MMW | Sodium hyaluronate powder HMW |
| Permeability | Strong, reaching directly to the vicinity of the dermis | Medium, penetrating the surface layer of the stratum corneum | Weak, only remaining on the surface of the skin |
| Core role | Deeply moisturize and repair the skin barrier | Moisturizing both surface and shallow layers, providing nourishment at the same time | Surface water lock and film formation for protection |
| Skin feel | Refreshing, without any sticky feeling | Moderately moisturizing, with a slight stickiness | It’s sticky and has a distinct film-forming effect |
| Suitable for skin type | All skin types, especially sensitive skin and oily skin | It can be used in combination with normal skin, combination skin and dry skin | Dry skin, desert skin, or scenarios that require strong protection |
Differences in application scenarios
Sodium hyaluronate powder LMW: Suitable for addition to essence, base lotion and repair masks, it mainly focuses on deep hydration and barrier repair.
Sodium hyaluronate powder MMW: Commonly used in lotions, face creams and ordinary moisturizing masks, it balances moisture and nourishment.
Sodium hyaluronate powder HMW: It is mostly used in moisturizing creams, body lotions and protective skin care products, focusing on moisture retention and surface protection of the skin.
The highlights of the differences from liquid sodium hyaluronate
Compared with liquid products, sodium hyaluronate in powder form is easier to store for a long time and does not require excessive preservatives, making it safer.
It has lower transportation costs, is small in size and light in weight, and is suitable for large-scale raw material transportation and storage.
The concentration is more adjustable. The liquid product has a fixed concentration, while the powder can be diluted or concentrated as needed, making it suitable for more scenarios.
