NOTES |
A503 Low bulk density fine powder, small grain size.
A211 – Standard quality powder
A215 – Faster reaction rate powder
A503 – Low bulk density powder
A611 – Standard low-viscosity paste
A621 – More reactive, higher viscosity paste
A651 – Highly concentrated gel, highly viscous
A661 – Most viscous Alugel available, resistant to sedimentation
A671 – Free flowing suspension, suitable for 2x or 3x strength formulations
A681 – Most highly concentrated Aluminum Hydroxide suspension available, highly stable.
Customers who use Alugel also purchase Sucralfate, an all-purpose antacid for immediate relief and long-term healing
Use: COSMETIC COLORANT, EMOLLIENT, HUMECTANT, OPACIFYING, SKIN PROTECTING, VISCOSITY CONTROLLING |
