Sodium Propylparaben CAS 35285-69-9
The substance corresponding to CAS 35285-69-9 is Sodium Propylparaben, also known as Sodium Sodium Propylparaben. Sodium Propylparaben is a water-soluble preservative widely used in food, cosmetics and pharmaceuticals.
Core selling point:
1.Excellent water solubility: Sodium salt dissolves directly in cold water. The formula does not require heating or solubilizers, simplifying the production process of cosmetics / water-based systems.
2. Broad-spectrum antibacterial, with a focus on fungicidal properties: Strong inhibitory effect on molds and yeasts. Combined with methylparaben sodium, it achieves comprehensive preservation of bacteria and fungi.
3. Low addition amount: The recommended regular addition amount is 0.1–0.3%. A low dose can achieve internal preservation in cans, with controllable costs.
4. specifications available: Cosmetics grade, food grade, meeting the certification requirements of different industries.

FAQ
Q: What is the appearance like?
A: Sodium Propylparaben is a white, moisture-absorbing crystalline powder with almost no odor.
Q: What is the recommended addition amount?
A: 0.1–0.3% for cosmetics; according to local regulations, it can be used in food systems in limited quantities; 0.05–0.2% for industrial water-based systems.
Q: What is the applicable pH range?
A: The optimal pH is 8–10; when the pH is lower than 6, n-propylparaben is prone to precipitate, and the antibacterial effect decreases, so it is not suitable for highly acidic formulations.
Q: Does the powder easily absorb moisture?
A: It is hygroscopic. After opening, it is easy to absorb moisture and form lumps. Storage must be sealed.
Q: Storage conditions and shelf life?
A: Store in a cool, dry warehouse, protected from moisture, away from strong acids; the original packaging has a shelf life of 24 months.
Q: Regular packaging and MOQ?
A: 25kg cardboard barrels / paper boxes; MOQ: 25kg. COA, MSDS, TDS can be provided; for cosmetic grade, relevant qualification documents can also be provided.
