Ceteareth-25 25 kg

What makes Ceteareth-25 a reliable choice for large-scale emulsion manufacturing

Ceteareth-25 is a nonionic emulsifier derived from a blend of cetyl and stearyl alcohols with attached ethylene oxide groups. Thanks to its high hydrophilic-lipophilic balance, it functions as a powerful oil-in-water emulsifier and simultaneously as a solubilizer capable of keeping poorly soluble ingredients dispersed within the water phase. This ingredient belongs to the Emulsifiers Bulk category, designed for manufacturers who need a consistent, predictable supply of raw material for continuous production lines. The 25 kg packaging is intended specifically for industrial and conveyor-scale manufacturing rather than small trial batches, where uniform performance from batch to batch is essential.

The primary demand for Ceteareth-25 comes from cosmetic emulsion production: nourishing and moisturizing creams, body lotions, hair conditioners and masks, as well as sun care formulations. It stabilizes formulas with a high oil phase content, prevents separation under storage temperature fluctuations, and keeps the texture uniform throughout the product's shelf life. Beyond cosmetics, Ceteareth-25 is widely used in household chemicals for cleaning agents and polishes, and in the textile industry for lubricating and leveling emulsions applied during fiber and fabric processing. In the broader chemical industry it also serves as a dispersing agent that helps combine otherwise incompatible components.

Ceteareth-25 pairs well with other nonionic emulsifiers and solubilizers, giving formulators flexibility to fine-tune viscosity and stability of the finished product. In formulations containing water-soluble oils and fragrance compositions, it is frequently combined with Polysorbate 80 100 kg, which improves the solubilization of oily additives in the water phase. For lighter textures with lower fat content, pairing with Polysorbate 20 100 kg works well, while high-volume production lines with substantial raw material consumption often rely on the larger Polysorbate 80 235 kg packaging to reduce order frequency and simplify warehouse logistics.

Ceteareth-25 should be introduced into the oil phase of a formulation during the heating stage, at around 70-75 degrees Celsius, once all fatty and waxy components have fully melted. The oil and water phases are then combined at matching temperatures and homogenized until a stable emulsion forms. Typical working dosage ranges from 2 to 8 percent of total formula weight, depending on the desired viscosity and fat content. Exceeding the upper dosage limit may result in an overly thick texture, so it is advisable to test a trial batch before scaling up to full production volume.

Store Ceteareth-25 in its original sealed container, in a dry area at room temperature, away from direct sunlight and heat sources. Proper storage preserves emulsifying performance throughout the entire stated shelf life, which is particularly important for manufacturers building raw material reserves for several production cycles ahead.

Body lotion base with Ceteareth-25

Distilled water 780 ml

Ceteareth-25 35 g

Cetearyl alcohol 35 g

Sweet almond oil 90 g

Glycerin 45 g

Preservative 8 g

Fragrance oil 5 g

Heat the water phase with glycerin to 75 degrees Celsius, while separately melting the oil phase containing Ceteareth-25, cetearyl alcohol and almond oil at the same temperature. Slowly pour the oil phase into the water phase under continuous mixing and homogenize until a smooth, stable emulsion forms. Once the mixture cools to around 40 degrees, add the preservative and fragrance oil, blend thoroughly, and transfer the finished lotion into clean containers.
