FORMULATION GUIDE

Formulation Compatibility Guide

We guide you to compatible formulations based on container type and dispensing method

Check First

Viscosity, usage mode, and desired dispensing feel are the main criteria for container choice.

Review Together

Neck specification and cap/pump compatibility should be checked together with formulation fit.

Recommended Flow

After the formulation guide, review sample policy and product detail together.

Cosmetic Formulation Types

Major formulation categories by viscosity and characteristics

Serum / Essence

Low ~ Medium viscosity

Low to medium viscosity liquid. Suitable for dropper or pump dispensing, with glass chemical resistance ensuring stable preservation.

Ampoule

Low viscosity

Highly concentrated low viscosity liquid. Optimal for small-volume dropper containers, with tinted glass protecting active ingredients.

Foundation / Base

Medium viscosity

Medium viscosity liquid to cream. Suitable for pump dispensing, with glass containers conveying a premium image.

Lotion / Emulsion

Medium viscosity

Medium viscosity emulsion. Suitable for pump dispensing, fillable in wide-mouth or standard neck containers.

Oil

Low viscosity

Low viscosity oil base. Optimal for dropper dispensing, with glass preventing oil oxidation.

Toner / Mist

Low viscosity

Low viscosity aqueous formulation. Suitable for spray pumps or regular caps, also used in large glass containers.

FAQ

Frequently Asked Questions

Which containers suit serums and essences?

Serums and essences are low to medium viscosity liquids suited to dropper or pump dispensing, and the chemical resistance of glass ensures stable preservation.

What container works for ampoule formulations?

Ampoules are highly concentrated low viscosity liquids, optimal for small-volume dropper containers, and tinted glass protects active ingredients.

Why is glass suitable for oil formulations?

Oils are low viscosity bases optimal for dropper dispensing, and glass containers prevent oil oxidation.

Which dispensing method fits toners and mists?

Toners and mists are low viscosity aqueous formulations suited to spray pumps or regular caps, and they are also used in large glass containers.

How are containers chosen for lotions and foundations?

Lotions and emulsions are medium viscosity emulsions suited to pump dispensing and can be filled in wide-mouth or standard neck containers. Foundations and bases range from medium viscosity liquids to creams and suit pump dispensing.
