The invention aims to solve the technical problem of providing the shapeable explosive salt, and the pasty fluid before the explosive salt is shaped has good rheological property, is easy to shape, and has various and beautiful shapes and strong interestingness. The molded product has proper hardness, is not easy to crack, and is more suitable for long-distance transportation and longer shelf life. The foam has the advantages of long foaming time, good foam performance, rich and fine foam, good foam stability and strong liquid carrying capacity when meeting water to generate a large amount of bubbles. The skin feel is good, and the skin is moist, smooth, not dry and not tight after use.

The technical scheme of the invention is as follows:

a moldable explosive salt comprises the following components in percentage by mass: 30-40% of sodium bicarbonate, 10-30% of alpha-hydroxy acid, 10-15% of light sodium carbonate or tower powder or a mixture of the light sodium carbonate and the tower powder, 0.1-3% of emulsifier, 3-8% of cocamidopropyl betaine, 10-15% of maltodextrin, 6-13% of soluble corn starch and 1-5% of polyethylene glycol.

Furthermore, in the mixture of the light sodium carbonate and the tower powder, the mass ratio of the light sodium carbonate to the tower powder is 1-3: 1-3. The tower powder and the light sodium carbonate have the density lower than that of water, have good water solubility and good compatibility with other components, and the specific gravity of the explosive salt can be adjusted by limiting the dosage proportion of the tower powder and the light sodium carbonate, so that the effect of floating and non-floating of the explosive salt is controllable.

Further, the alpha-hydroxy acid is at least one of anhydrous citric acid, tartaric acid and fumaric acid. The alpha-hydroxy acid can react with light sodium carbonate or sodium bicarbonate to generate corresponding sodium salt and carbon dioxide, so that a large amount of bubbles can be generated by the explosive salt when meeting water.

Further, the emulsifier is alkyl glycoside and alcohol ether glycoside. The two have small irritation to skin, can relieve irritation of other components to human body, and has strong foaming ability, good foam performance, stable foam, and strong decontamination capability.

The carboxymethyl chitosan molecular structure has polar group hydroxyl and carboxyl, and can form interface adsorption with the interaction of hydrogen bonds on alkyl glycoside and alcohol ether glycoside, so that the surface tension of the system is reduced, the foaming performance of the system is enhanced, meanwhile, the hydrogen bonds of the carboxymethyl chitosan can be combined with water, the net structure has good water locking capacity, the thickness of a liquid film is enhanced, and the stability of foam is further enhanced. After the carboxymethyl chitosan is combined with the alkyl glycoside and the alcohol ether glycoside by the interaction of hydrogen bonds, the micelle structures of the alkyl glycoside and the alcohol ether glycoside can be changed, and the micelle space of the alkyl glycoside and the alcohol ether glycoside is enlarged, so that the carboxymethyl chitosan has stronger solubilizing capability on oil.

The cocamidopropyl betaine can change the micelle structure of the anionic surfactant, further improve the solubilizing capability of the grease, improve the rheological property of the product before forming, and has good ductility and easier shaping.

The grease has the functions of bonding and moisturizing the skin in the system, the grease content is increased, the product is not easy to crack after being formed, the forming retention time is long, and the product is more suitable for long-distance transportation and longer shelf life; meanwhile, the moistening degree of the product is improved, the grease can form a barrier on the surface of the skin in the using process of the product, the moisture is preserved, the water is supplemented and locked, the irritation of other components can be reduced, and the skin is moist, soft and smooth, and is not dry and tight after use. The dosage of the grease is lower than the limit value of the invention, the product is easy to be cracked after being formed, the irritation is strong, and the skin feel is poor; the dosage is higher than the limit value of the invention, the product is difficult to form, the paste body is easy to collapse and deform during shaping, the grease is easy to separate, the foam performance is reduced, and the skin feel is sticky and greasy after use.

Further, the grease is propylene glycol dicaprylate/decanoate, squalene and vegetable grease. The three types of grease are matched to achieve excellent moisturizing effect, light and thin skin feel, have small influence on the degreasing force of a living system, and do not influence the foaming performance and the foaming capacity of the product.
