White polyethylene microgranules, 100 g

Why polyethylene microgranules work as a universal exfoliating and finishing filler

White polyethylene microgranules in a 100 g package are a free-flowing filler with uniform particle size that finds use both in cosmetic manufacturing and in several technical industries. In personal care formulations this ingredient is most commonly used within the Scrubs for Cosmetic Production category, acting as a mechanical abrasive for body and facial exfoliating products. The compact 100 g size is well suited for home experimentation, sample batches and formula testing before moving to a larger production run.

When added to a cosmetic base, the granules should be introduced at the final stage of production once the mixture has cooled to around 40-45 degrees Celsius, since higher temperatures cause the particles to soften and lose their defined shape. Typical usage levels range from 3 to 15 percent of the finished product weight, depending on the desired exfoliation strength. To build a more layered texture, formulators often blend these granules with plant-based abrasives such as rosehip scrub for a gentler finish, grape peel scrub for a medium abrasive profile, or almond scrub for a firmer mechanical effect.

Beyond cosmetics, polyethylene microgranules are widely applied across industrial fields. They serve as a matting additive in powder coatings and printing formulations to control surface roughness, as a hardness modifier in candle production, and as a filler in polishing pastes and mild abrasive blends used for surface treatment where a gentler action than sand or mineral abrasives is required. In plastic film and sheet manufacturing, similar granules are sometimes used as an anti-blocking agent to prevent sheets from sticking together during storage and transport.

The material should be kept in a dry area at room temperature, away from direct sunlight and heat sources, since prolonged exposure to elevated temperatures can cause the granules to soften and clump together, reducing their functional properties. Containers should be closed tightly after each use to prevent moisture or foreign particles from entering the material.

It is worth noting that these granules do not dissolve in either the water or oil phase of a formulation and are distributed mechanically throughout the mixture, so thorough mixing before packaging is essential to avoid settling at the bottom of the container.

Trial batch foot scrub bar

Shea butter 25 g

Coconut oil 20 g

White polyethylene microgranules 15 g

Beeswax 10 g

Essential oil blend 3 g

Vitamin E oil 2 g

Melt the shea butter, coconut oil and beeswax together in a water bath at around 60-65 degrees Celsius until fully liquid. Remove from heat and allow the mixture to cool to about 45 degrees before adding the vitamin E oil and essential oil blend, stirring gently. Once the temperature drops to around 40 degrees, fold in the polyethylene microgranules evenly without overmixing to preserve their shape, then pour the mass into small molds and let it solidify at room temperature for several hours before unmolding and packaging.
