Do You Know Cosmetic Grade Sodium Hyaluronate

Cosmetic grade sodium hyaluronate is sodium hyaluronate specifically designed for skin care products and complies with global cosmetic raw material standards. It is also the legal and safe usage level of this ingredient in skin care products. The core value of Cosmetic grade sodium hyaluronate lies in its combination of highly effective moisturizing function and strict safety, and it can be adapted to the forms and skin types of various skin care products.

Characteristics of cosmetic grade sodium hyaluronate

1. Core production standard: Ensure external safety

Cosmetic-grade sodium hyaluronate cas 9067-32-7 is not an ordinary raw material and must meet strict industry standards, which is the basis for its safe use on the skin.

High purity and low impurities: The purity is usually required to be ≥90%, while strictly limiting the content of harmful impurities such as heavy metals (such as lead and mercury) and microorganisms (such as bacteria and mold) to avoid skin irritation or infection.

Precise molecular weight control: Sodium salt hyaluronic acid will control its molecular weight within the range of 1kDa to 2000kDa based on skin care needs (surface moisture retention or deep hydration). Different molecular weights correspond to different skin layers of action, ensuring precise efficacy.

Compliance certification: It must comply with the international Cosmetic Ingredient Nomenclature (INCI) standards and regional regulations (such as China’s “Cosmetic Safety Technical Specifications” and the EU Cosmetic Regulations) to ensure its legal use in the production of skin care products.

2. Key features: Compatible with skincare product scenarios

Compared with pharmaceutical-grade and food-grade sodium hyaluronate, cosmetic grade sodium hyaluronate is more in line with the external application requirements of the skin in terms of characteristics rather than for injection or consumption scenarios.

Solubility and stability: Cosmetic Grade sodium hyaluronate powder has good water solubility and can be evenly integrated into various skin care products such as essence, mask, lotion, etc. Moreover, it is not easy to degrade within the shelf life, ensuring stable efficacy.

Skin feel optimization: Through process adjustment, the sticky feeling is reduced. After use, a refreshing and moisturizing film is formed on the skin surface, which does not affect the experience of using skin care products. It is suitable for both dry and oily skin.

Low allergenicity: During production, allergenic impurities are avoided, and skin irritation tests must be passed. Under normal use, it is also friendly to special groups such as sensitive skin and pregnant women (other irritating ingredients in the product need to be excluded).

3. Core differences from other levels

Sodium hyaluronate of different grades varies greatly in standards and properties due to their different uses and should not be confused.

Cosmetic grade sodium hyaluronate is of high purity, controlled molecular weight, good skin feel and low irritation. It is suitable for skin care products and cosmetics. The quality of skin care products varies greatly. Many people are very concerned about whether sodium hyaluronate is safe in skin care. Let’s talk about the common concerns below.

Is sodium hyaluronate safe in skincare?

The core basis for security

Homology in the human body: Sodium hyaluronate is a substance that is naturally present in the human body, mainly found in the skin, joint fluid and other areas. When used externally, it is less likely to cause rejection by the immune system or allergic reactions.

Long-term and wide application: This ingredient has been used in the field of skin care products for decades. A large amount of clinical and actual usage data show that at normal concentrations (usually 0.1%-2%), it does not irritate healthy skin.

Regulatory authorities recognize: Sodium, salt, hyaluronic acid. Major global authoritative institutions, including the US FDA and the EU cosmetics regulatory agency, all list it as a safe cosmetic ingredient.

Cosmetic grade sodium hyaluronate can achieve the dual effects of “surface water retention + deep water replenishment” by regulating the molecular weight. Macromolecules remain on the skin surface to form a moisturizing film, reducing water evaporation. Small molecules penetrate into the stratum corneum, replenishing deep moisture in the skin and preventing the “oily exterior and dry interior” or “tight surface” caused by single moisturizing. Cosmetic grade sodium hyaluronate has good water solubility and stability. It can be evenly integrated into almost all skin care product forms such as essence, mask, lotion and cream, and will not have adverse reactions with other ingredients (such as vitamin C and nicotinamide), and is convenient for combination use.
