Frequently Asked Questions

How many drops in a 100ml dropper bottle?

The standard medical and pharmaceutical convention is 1ml = 20 drops when using a standard dropper. This is based on the ISO 8362 standard for dropper tips. It is the widely accepted figure used by pharmacists, aromatherapists, and cosmetic formulators globally. So for a 100ml glass dropper bottle: 100ml × 20 drops = 2,000 drops. That is 2,000 precisely dispensed drops per bottle. Outstanding value for professional and bulk-use formulations.

What is the best dropper bottle size for carrier oils?

The best dropper bottle size for carrier oils is 100ml. Carrier oils are used in generous quantities for massage, hair treatment, and formulation blending. The 100ml cobalt blue glass dropper bottle provides enough volume for professional use. The precision dropper tip ensures controlled, mess-free dispensing. The best dropper bottle size for carrier oils in a wholesale or clinic context is consistently the 100ml format.

Is a 50ml dropper bottle too large for serums?

Is a 50ml dropper bottle too large for serums? Not necessarily — but for high-concentration actives, 30ml is the preferred retail size. The 100ml dropper bottle is better suited for carrier oils, base formulations, and professional dispensing. For serums, 15ml to 30ml remains the consumer sweet spot. The 100ml format is the professional’s choice for bulk blending and clinic use.

The UV protective glass bottle advantage is especially valued for light-sensitive actives and botanical extracts.
