Octyl 4-Methoxycinnamate is a formulation ingredient used as a UVB filter in sunscreen, sun care, and related personal care formulations. In B2B supply, it is typically handled as a liquid raw material for formulation systems where UV protection performance and compatibility with the overall formula need to be evaluated by the buyer. In practical supply terms, it is commonly offered in standard export packaging, with packaging arrangements based on order volume and supply format, and supporting documents such as COA, TDS, and SDS can be provided with shipment support. Its use in finished products should be reviewed against the regulatory requirements of the destination market.

Packaging
Octyl 4-Methoxycinnamate is generally supplied as a liquid raw material in sealed containers suitable for routine chemical and formulation-ingredient handling. Export packaging can be arranged according to order quantity, logistics requirements, and customer handling preference. Clean container condition, sealed packing, and protection against leakage and contamination should be maintained throughout storage and transport. For regular procurement, packaging can be coordinated to match batch size and bulk supply requirements.
Storage
Store in a cool, dry, and well-ventilated place in tightly closed original containers. Keep away from direct sunlight, excessive heat, and sources of ignition. Avoid contamination and maintain package integrity during warehousing and transport. Long storage periods should be managed under suitable stock rotation and specification control.
