3. Dropper Bottle Characteristic

Dark glass material: Dark colors can effectively block ultraviolet rays, preventing essential oils from undergoing photochemical reactions and deteriorating due to light exposure.

Sealed bottle cap: The cap is equipped with an inner stopper/dropper and a hole cover. The inner stopper is used to control the flow rate, allowing for drop-by-drop dispensing; the outer cover ensures the bottle opening is sealed to prevent evaporation and external contamination.

Dedicated dropper/rubber head: For thicker essential oils or those requiring precise measurement, a glass dropper with a black rubber head will be provided for easy suction and dispensing.

4.Dropper Bottle Technology

Glass forming technology: A molding process is used to inject molten glass into molds, creating standard capacity bottle bodies with uniformly thick walls and precise neck dimensions to ensure sealing.

Glass coloring technology: Metal oxides (such as sulfur and carbon to form amber color, cobalt to form blue) are added to glass raw materials to give it a stable protective color.

Inner plugs: Usually made of high-density polyethylene (HDPE) or polypropylene (PP), these chemically resistant plastics ensure a tight fit with the bottle neck due to their elasticity.

Droppers: A combination of glass droppers and rubber or plastic tips, where the tip is required to have good elasticity and oil resistance.

Anti-theft and sealing structures: Many bottle caps are designed with anti-theft rings that break upon first opening, ensuring that the product has not been opened or used. The screw thread design is also precisely calculated to guarantee sealing.
