Corn Scrub (from Cob, 60-80 Mesh) is a cosmetic-grade particulate exfoliant produced from processed corn cob and standardized as ZEA MAYS COB MEAL for rinse-off skin-cleansing systems.

This material works through mechanical exfoliation rather than chemical activity. It helps lift dull surface buildup and supports a cleaner skin feel when suspended in gels, cream cleansers, masks, and scrub bases. Because the performance depends mainly on particle loading, base viscosity, and massage pressure, it is best positioned as a formulation tool for tactile exfoliation rather than as a biochemical active.

The particles are fully microbial controlled and intended for use as a stable scrub phase in conventional cosmetic processing. In formulation work, the main technical concerns are uniform suspension, particle integrity, and matching the particle feel to the final product format and target skin area.

Product Description: Corn cob scrub particles provide physical exfoliation and sensorial texture in rinse-off systems. Unlike soluble actives, this ingredient does not need conversion or release to function; performance depends on particle size, concentration, suspension stability, and how evenly the base distributes particles over the skin. It fits best in facial or body scrubs, cleansing gels, cream cleansers, wash-off masks, and exfoliating bars where visible or tactile particles are desired. In very low-viscosity systems, sedimentation should be evaluated during stability testing; in high-shear manufacturing, excessive mixing after particle addition can reduce particle integrity or change the scrub feel. The ingredient is generally formulation-stable across normal cosmetic pH ranges because it behaves as an insoluble solid phase, but finished-product aesthetics should still be checked after heating, cooling, and transport cycling.

Usage: Rinse-off facial scrubs, body scrubs, cleansing gels, cream cleansers, wash-off masks, and exfoliating bar systems.

Mixing method:

- Add after the base is already homogeneous, ideally in the final stage or after emulsification, then mix with moderate shear until evenly suspended.

- For gels and surfactant cleansers, add slowly to avoid air incorporation and check suspension over time; adjust viscosity if particles settle.

- For emulsions or scrub creams, add during cool-down or late processing to preserve particle integrity and final scrub feel.

- Screen final pH, viscosity, and pack compatibility during stability testing; the ingredient should remain as suspended particles rather than dissolve.

Usage rate: 0.1-15%. A practical working range is often around 1-10% depending on the desired scrub intensity and particle feel.

Product characteristics: Cream to light brown particulate powder with mild natural odor.

Solubility: Insoluble in water; used as a dispersed solid phase in water-based, surfactant-based, oil-containing, and cream/gel scrub systems.

Storage: Store tightly closed in a dry area at room temperature. Protect from moisture pickup to maintain free-flowing particles and consistent scrub feel.
