How Vegetable Glycerin Works in Paint Making
Vegetable glycerin is used in paint as a humectant to retain moisture and a plasticizer to improve flexibility.
-
It prevents watercolours from drying out too quickly and helps them remain easy to rewet.
-
It softens gum Arabic, reducing brittleness and preventing paint from flaking off the paper.
-
It helps maintain paint consistency, ensuring smooth application and long-lasting quality.
The correct balance is essential:
-
Too much glycerin makes the paint sticky and slow to dry.
-
Too little glycerin makes the paint hard and difficult to rewet.
Proper formulation ensures stable, high-performance paint.
