One of the prerequisites to ensure that the product can be optimally assisted in the tanning process is that the wet-blue is applied at the right pH and with the right penetration possibilities.
The neutralisation process is an important step in preparing all these products to penetrate evenly and deeply into the leather.
Different processes in the tanning process require different emphases, and for neutralisation, soft cushioning properties and deep lasting action are particularly important.
After intensive research and development by the Texel team, a new product has been launched:
the high cushioning performance neutralising tannin DESOATEN NSK
● Excellent cushioning and penetration properties
● Improved penetration of chemical materials
● Get a more spacious and even finished leather
DESOATEN NSK Excellent pH buffering properties
In order for the pH to be close to the isoelectric point of the wet-blue and to ensure adequate penetration of all anionic materials, the pH needs to be adjusted to a range of 4.5 to 6.5 using alkaline materials during the neutralisation process.
However, violent fluctuations in pH are very negative for the tanning process and the poor penetration of strong alkalis tends to cause an uneven distribution of pH on the cut surface of the leather, leading to an excessive build-up of chemical material on the grain surface, which cannot penetrate evenly.
While Decision presents
high cushioning performance neutralising tannins DESOATEN NSK.
Its excellent buffering properties ensure a soothing and gentle pH change of the wet-blue, a flat and fine grain, an even dyeing and a uniform consistency between the skins.
Its buffering properties also help the full penetration and homogeneity of the wet-blue cross-section, ensuring the performance of dyeing through the leather heart, full penetration of tanning and fatliquoring agents, leather stretching and better leather yield.

Love is like the warm breeze of a willow that does not chill your face
Love is like the warmth of a lover’s embrace
Love is a gentle and silent soothing touch
High cushioning performance neutralising tannin DESOATEN NSK
Like a “gentle and firm” sweet guy who soothes the “impulsive” pH value. On this special day, chemistry was also romanticised.
As a responsible enterprise we will carry this as our obligation and work persistently and indomitably towards the final goal.
