FAQ
Q: What is the appearance like?
A: It is a white to off-white needle-like crystalline powder. It oxidizes easily upon exposure to light and air, gradually turning yellow.
Q: Why is it required to store in a dark place?
A: Amines are prone to oxidation. In an environment with light and air, they will gradually turn yellow and change color, affecting the purity and color of the product. Therefore, it must be stored in a sealed and dark place.
Q: Can it be directly used as a sunscreen raw material?
A: PABA itself can absorb UVB. However, most cosmetic formulations now use its ester derivatives. Regulations in many regions restrict the direct addition of PABA to finished sunscreen products. Customers need to confirm the local cosmetics regulations themselves.
Q: Storage conditions and shelf life?
A: Store in a sealed, cool, dry place, away from oxidants. Normal storage shelf life is 24 months.
Q: Packaging specifications, MOQ (Minimum Order Quantity)?
A: Regular packaging is 25kg in cardboard barrels. Provide samples. MOQ: 25kg. COA, MSDS, and TDS can be provided.
Q: Delivery time?
A: Regular inventory. After receiving the deposit, the goods will be dispatched within 3-7 working days; for large orders, it will take 7-12 working days.
Q: Does it support urgent orders?
A: Urgent orders are available. Please confirm the inventory in advance; when the raw materials are sufficient, the goods can be dispatched within 2-4 working days. Urgent orders will incur additional costs.
