Embodiment 1

[0043] Embodiment 1: the preparation of yellow food grade crayon

[0044]

[0045]The base used in this example is pure beeswax without adding any other petrochemical waxes, which fundamentally ensures that the prepared crayons contain zero heavy metals. Beeswax is decolorized yellow beeswax, the price is much lower than that of white beeswax, high in quality and low in price, at the same time, the original yellow impurities have been removed to make the wax body white and easy to color.

[0046] The sodium stearoyl lactylate used in this embodiment can promote the mutual fusion of various substances, and has excellent properties such as leveling, emulsification, wax protection, corrosion inhibition, wetting, diffusion, and antistatic properties. Emulsifiers can be dispersed in warm water and ethanol, soluble in organic solvents such as propylene glycol, liquid paraffin, ethanol, methanol or ethyl acetate, and are often used as emulsifiers or dispersants for medicines and f...

Abstract

The invention discloses a pure beeswax heavy-metal-free food-grade crayon capable of preventing mistaken eating and protecting skin and a preparation method thereof, and belongs to the technical fieldof novel coatings. The pure beeswax heavy-metal-free food-grade crayon capable of preventing mistaken eating and protecting skin is prepared from the following components in parts by weight: 3 to 10parts of beeswax, 0.5 to 5 parts of an emulsifier, 0.01 to 1.0 part of a coloring agent, 0.05 to 1.5 parts of an aversive agent, 0.05 to 1.5 parts of a skin care agent, 0.0001 to 0.0006 part of a preservative and 0.1 to 1.5 parts of a filler. According to the invention, the used matrix is food-grade pure beeswax, and the pigment is a food-grade pigment and does not contain heavy metals; and the filler has the effect of improving the writing smoothness, hardness and color rendering of the crayon. The obtained crayon is uniform in pigment mixing, is not sticky to hands, is high in writing smoothness, moderate in hardness, bright in appearance color and good in overall effect.

Description

technical field [0001] The invention belongs to the technical field of new coatings, and in particular relates to a food-grade crayon which is pure beeswax free of heavy metals and can prevent accidental ingestion and skin care. Background technique [0002] Crayons are loved by parents and children as a kind of paint. Graffiti can develop children's brains and exercise their spatial thinking ability. The safety of crayons is the core concern of parents. Crayons on the market today are basically made of paraffin wax and industrial pigments, which contain more harmful heavy metals, such as lead, cadmium, barium, antimony, etc., which pose a great safety hazard to children and adolescents who are weak in safety awareness, and often cause mistakes. Dangerous behaviors such as eating and smearing the skin will cause heavy metal poisoning and threaten their health. [0003] It can be seen from the market research that most of the crayons sold in the market today will have pigm...
