Cationic Sodium Hyaluronate – Frequently Asked Questions (FAQ)

1. What is Cationic Sodium Hyaluronate?

Cationic Sodium Hyaluronate is a positively charged derivative of traditional sodium hyaluronate (HA). It is specially modified to improve adhesion to negatively charged surfaces such as skin and hair, providing longer-lasting moisturization and conditioning effects.

---

2. How does Cationic Sodium Hyaluronate differ from regular Sodium Hyaluronate?

Conventional sodium hyaluronate carries negative charges and does not bind well to skin or hair, which are also negatively charged.
Cationic Sodium Hyaluronate, however, contains positively charged functional groups that enable electrostatic attraction, improving its deposition, retention, and overall moisturizing performance.

---

3. What are the main benefits of using Cationic Sodium Hyaluronate in cosmetics?

• Long-lasting hydration and moisture retention

• Enhanced skin and hair adhesion

• Improved smoothness and softness

• Stronger barrier protection

• Reduced wash-off during cleansing or rinsing

• Ideal for long-lasting moisturizers, conditioners, and hair treatments

---

4. Is Cationic Sodium Hyaluronate safe for skin and hair?

Yes. It is derived from natural sodium hyaluronate and modified through a mild cationic process that maintains biocompatibility. It is non-irritating, non-toxic, and suitable for sensitive skin and scalp applications.

---

5. What types of formulations is it suitable for?

Cationic Sodium Hyaluronate can be widely used in:

• Facial and body moisturizers

• Serums and essences

• Hair conditioners and masks

• Shampoos and leave-in treatments

• Makeup bases and skin primers

---

6. What concentration is recommended in formulations?

The recommended dosage is typically 0.05–1.0%, depending on product type and desired sensory effect. For hair care applications, slightly higher levels may be used to improve conditioning performance.

---

7. How does it improve hair care products?

The cationic charge allows it to bond firmly with the hair cuticle, forming a hydrating, protective film that enhances smoothness, shine, and manageability while reducing frizz and breakage.

---

8. Does it affect the viscosity or stability of cosmetic formulations?

Cationic Sodium Hyaluronate has minimal impact on viscosity and is compatible with most cosmetic ingredients. It can be easily incorporated into aqueous systems and emulsions under normal formulation conditions.

---

9. Is it compatible with anionic surfactants or other ingredients?

Yes. Despite its cationic nature, it shows good compatibility with common anionic surfactants used in shampoos and cleansers, making it a versatile moisturizing and conditioning additive.

---

10. What is the source of raw material?

The base material—sodium hyaluronate—is typically derived from natural fermentation of non-animal sources, ensuring sustainability, purity, and safety for global cosmetic applications.

---

11. What are the storage and stability recommendations?

Store in a cool, dry place away from direct sunlight and moisture. When properly stored, the product maintains stability for up to 24 months in its original, unopened packaging.
