Ceteareth-25 50 g

Why Ceteareth-25 Improves Cream Stability in Skincare Manufacturing

Ceteareth-25 is a non-ionic waxy ingredient widely used as a co-emulsifier and viscosity booster in oil-in-water emulsions across the skincare and pharmaceutical manufacturing sectors. It belongs to the Emulsifiers category, which brings together ingredients responsible for keeping creams, lotions and body milks stable without separation over time. The primary industrial use of this ingredient is in the production of moisturizing creams, ointment bases and stabilized emulsion systems where consistent texture must be maintained throughout the shelf life of the finished product.

Ceteareth-25 is rarely used on its own - its main role is to support a primary emulsifier, increase the thickness of the formula and improve the sensory feel of the finished cream on skin. It pairs well with self-emulsifying wax systems such as Olivem 1000 25 g, giving the cream a richer, denser body. It can also be combined with softer gel-type emulsifiers like Sucragel AOF 10 g when a lighter texture with better thermal stability is required. In more complex formulations, it works alongside Emulsifier Beautyderm K10, 30 g, allowing formulators to balance richness with fast absorption.

In a typical formulation, ceteareth-25 is added to the oil phase and dissolved together with other fatty ingredients at 70-75 degrees Celsius, after which the oil phase is combined with a pre-heated water phase under constant stirring. Recommended dosage ranges from 1 to 5 percent of the total formula weight, depending on the desired thickness and stability of the emulsion. Higher concentrations can create an overly heavy film on skin, so small test batches are recommended before scaling up production volumes.

Main industrial applications include moisturizing and nourishing creams, body lotions, after-sun and after-shave balms, as well as certain ointment bases used in pharmaceutical manufacturing. It also occasionally appears in household chemical products, such as cream-type cleaning formulas that require a stable, non-separating consistency. Mentions in traditional soap making are minimal and limited to specific cream-based soap systems.

The 50 g package size is convenient for home cosmetic making and small trial batches, allowing formulators to test a recipe before scaling to larger production runs. Store the ingredient in a cool, dry place away from direct sunlight, in a tightly closed container, to prevent oxidation and texture changes during long-term storage.
