PEG 100 1 kg

Why PEG 100 Remains a Core Building Block in Cream Formulations

Emulsifier PEG 100 is a nonionic surface-active compound widely used in the manufacturing of oil-in-water cosmetic emulsions. It belongs to the section Emulsifiers, which brings together ingredients responsible for binding water and oil phases into a stable, uniform product. The 1 kg packaging suits small-batch and studio-scale cosmetic production, as well as laboratories developing and testing formulations before scaling up to larger manufacturing volumes.

The primary industry driving demand for this compound is cosmetic manufacturing: facial and body creams, lotions, hair care emulsions, and sun care products. It is most commonly paired with glyceryl stearate, forming the classic self-emulsifying wax combination that delivers a smooth texture and long-term stability in finished formulas. Beyond skincare and color cosmetics, this emulsifier is also applied in pharmaceutical cream and ointment production, as well as in certain household chemical formulations requiring a reliable water-oil system.

Recommended usage rates range from 3 to 6 percent of the total formulation weight, depending on the oil phase volume and composition. The ingredient should be added to the oil phase during heating to around 70-75 degrees Celsius, after which the oil and water phases are combined at matching temperatures under continuous stirring until a homogeneous mixture forms. This method produces a finely dispersed emulsion structure and prevents phase separation over the shelf life of the product.

This emulsifier blends well with vegetable oils, silicones, waxes, and active ingredients, and is compatible with gum-based or polymer thickeners. For a lighter, silkier cream texture, formulators often combine it with SILKY SHEA, which adds a velvety slip to the finished emulsion. In formulations requiring extra thermal stability across storage conditions, chemists frequently add Emulsifier XYLIANCE or Emulsifier Neowax 165 as co-emulsifiers to strengthen texture and consistency.

Store the emulsifier in a tightly sealed container, in a dry area at room temperature, away from direct sunlight and moisture. When storage conditions are respected, the product retains its functional properties over an extended period, making the 1 kg packaging practical for regular production cycles in a small cosmetic studio.

Lightweight Daily Body Lotion

Distilled water 70 g

SILKY SHEA butter 7 g

Sweet almond oil 6 g

Emulsifier PEG 100 5 g

Glycerin 4 g

Aloe vera extract 3 g

Preservative 1 g

Fragrance oil 0.5 g

Heat the water phase with glycerin and aloe extract to 75 degrees Celsius, and separately heat the oil phase with the emulsifier to the same temperature. Slowly pour the oil phase into the water phase while stirring continuously, homogenize until smooth, then cool the mixture to 40 degrees before adding the preservative and fragrance oil. Stir until fully cooled and pour into bottles or jars.
