Lac Extract – is a red dye extract from the scale insect Kerria Lacca.
The Lac insects invade host trees mainly Albizia Lucidor, Combretum Quadrangulare, Cajanus Cajan, Zizyphus Mauritiana and Schleichera, the insect secretes a resin that contains the red dye. The resin is harvested from the branches and is known as stick lac.
There are two primary components, the resin and the dye. To be useful for dyeing the colorant is separated from the resin – it is then referred to as Lac Dye.
Note : Lac dye is not made by killing the insect whereas it is made for the waste which is excreted by the insect.
Lac extract yields a range of reds from crimsons to burgundy. The colourant is similar to cochineal.
