NOTES	A621 In comparison with the standard quality A611, ALUGEL A621 has an elevetaed antacid reactivity. 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
