- Provides optimum balance of luxirious softness and silkiness.
- Minimum impact on tissue absorbency
- Virtually non-yellowing on tissue paper
- Can be applied on both virgin and recycled tissue paper
- Water based, easy to dilute and use.
- Contains no organic lotions; based on silicone material
- Excellent emulsion stability and shear stability in the application bath

Since HA-1 tissue softner is a concentrate, pre-dilution with water in advance of applying at the dry-end of multiple ply tissue sheets is recommended. Although it depends on how dry the treated sheets are, a 1:1 dilution with water is most commonly used.HA-1 tissue softener may be applied on the tissue sheets by spraying or kiss-roll coating with gravure rollers, just after ply-bonding (or edge-embossing) to avoid potential ply bonding issues. It that is not possible, it can be also applied by printing of padding after Yankee dryers in papermaking process. However, the former proces is usually preferable.Applying HA-1 tissue softener on each ply (two outer plies in case of more than 3 plies consisting of a tissue sheet) is recommended to acheie the maximum emollient effect on tissue.The suggested starting add-on level of 1:1 dilution of HA-1 tissue softener is typically 2~3% of the weight of whole tissue sheets. Depending on the softness needed, the quantity of HA-1 to be added can be varied.
