ABSTRACT: Due to their lower environmental impact, ease of accessibility, low cost,
and biodegradability, bio-renewable sources have been used extensively in the
last several decades to synthesize adhesives, substituting petrochemical-based
adhesive. Vegetable oils (including palm, castor, jatropha, and soybean oils),
lactic acid, potato starch, and other bio-renewable sources are all excellent
sources for the synthesis of adhesives that are being taken into consideration
for the synthesis of “eco-friendly” adhesives. Due to their widespread use,
accessibility, affordability, and biodegradability, biobased raw materials like
carbohydrates used to synthesize wood and wood composite adhesive have gradually
replaced petrochemical-based adhesive. Recently, xanthan gum, a naturally
occurring polymer, has drawn the interest of scientists as a potentially
petroleum source replacement. It possesses specific rheological
characteristics, excellent water solubility, and stability to heat, and can be
used as a binder, thickener, suspending agent, and stabilizer. Xanthan gum
increases the adhesive strength in addition to increasing the viscosity of
water-soluble adhesives. This article discusses xanthan gum as a potential
substitute for traditional raw materials derived from petroleum that is used as
a raw material for adhesives.
