Microcrystalline wax used for crayon processing

The Core Role of Microcrystalline Wax in Crayons
Enhancing Product Performance: Microcrystalline wax possesses excellent
flexibility and high elongation, effectively increasing the plasticity and
flexibility of crayons, making them less prone to breakage. Simultaneously,
it prevents oil migration, avoiding grease seepage that could contaminate
packaging or surfaces, and facilitates demoulding during production.
Improving Production Processes: Microcrystalline wax exhibits excellent
compatibility with paraffin wax, various mineral waxes, vegetable waxes, and
pigments, ensuring thorough blending and uniform crayon texture. Its broad
melting point range (typically 60–90°C) allows adjustment of overall crayon
hardness, melting temperature, and solidification rate by selecting waxes
with different melting points.
Expanding application domains: Microcrystalline wax is a key component in
manufacturing water-soluble crayons. When combined with non-ionic
emulsifiers, it enables crayons to self-emulsify in water, facilitating easy
cleaning. It is also employed in producing multi-coloured and eco-friendly
crayons to enhance tactile feel and antimicrobial properties.
