Myrobalan extracts provide a light greenish yellow colour to tanning liquors and leathers and they are used especially in the first steps of tanning sole leathers to compensate for the reddish colour of tanning agents such as mimosa and quebracho extracts. The extracts are available in powder form and give leathers a uniform colour and a soft touch. Due to myrobalan's high sugar content, the extracts ferment easily.
