detailed description

The invention is further described below and examples of the invention are given.

This solid bath film that can be cut and used is characterized in that: it is made up of PVA colloid and bath solution; wherein said PVA colloid and bath solution are prepared in a ratio of 4:1; said colloid is made up of Composed of PVA, glycerin and deionized water, and according to PVA: glycerol: deionized water is 10:1:89 weight ratio preparation; Described bath liquid is made of green surfactant, skin care agent, thickener, pH Conditioning agent, flavoring agent, antioxidant and deionized water; the bath solution is composed of 15-25 parts by weight of surfactant, 5-10 parts by weight of skin care agent, 1-2 parts by weight of thickener, and pH regulator 0.5-1 part by weight, 0.05-0.1 part by weight of flavoring agent, 0.05-0.1 part by weight of antioxidant, and 60-70 parts by weight of deionized water.

The reason why the present invention selects PVA as the colloid material of making bathing film, except considering that PVA (polyvinyl alcohol) is a kind of macromolecular organic matter, white, tasteless, has synthesis convenience, safety and low toxicity, product quality is easy to control, cheap, In addition to the characteristics of easy use, the more important thing is that the material is soluble in water and is a commonly used safe film-forming agent, which will not cause environmental pollution during use.

The green surfactant is composed of one or more mixtures of fatty alcohol polyoxyethylene ether sodium sulfate, cocamidopropyl betaine and lauryl betaine.

Lauryl betaine, sodium fatty alcohol polyoxyethylene ether sulfate, and cocamidopropyl betaine are green surfactants, and their respective effects are as follows:

Dodecyl Betaine: It has excellent decontamination and sterilization, softness, antistatic, hard water resistance and rust resistance, and can be compatible with various surfactants and cosmetic raw materials. It is a zwitterionic surfactant and is good for skin Low irritation, effective foam booster and foam stabilizer, it can produce rich and stable foam in bath solution.

Fatty alcohol polyoxyethylene ether sodium sulfate: it has excellent detergency, emulsification, foaming performance and hard water resistance, is not affected by water hardness, foams quickly, has mild washing properties and will not damage the skin, and is now an excellent Raw material for washing products.

Cocamidopropyl Betaine: It is a zwitterionic surfactant, often used together with anionic, cationic and nonionic surfactants, and has good compatibility. Small irritation, easily soluble in water, stable to acid and alkali, strong detergency, good foaming effect, fine and stable foam, at the same time, has excellent thickening, softness, bactericidal, antistatic, Hard water resistance, mild performance, can significantly improve the softness, conditioning and low temperature stability of laundry products.

The skin care agent is composed of one of propylene glycol and glycerin, or a mixture of the two.

Propylene glycol and glycerin are skin care agents, and their respective functions are as follows:

Propylene Glycol: Propylene Glycol will be adsorbed on the skin surface during bathing, and it is not easy to wash away with water. After the surface moisture evaporates, a protective film is left to cover the skin, which can effectively prevent or slow down the loss of internal moisture and keep the skin moist.

Glycerin: Glycerin is the most common moisturizer. It has a good moisturizing effect and can effectively prevent chapped skin. Glycerin is hygroscopic and can absorb moisture in the air to moisturize the skin and prevent the loss of moisture in the skin.

The natural thickener is composed of one of pectin or gelatin, or a mixture of both.

Pectin and gelatin are natural thickeners, and their respective functions are as follows:

Pectin: Pectin is a plant polysaccharide substance that can form an elastic gel and increase the viscosity of a liquid.

Gelatin: Gelatin is a partially hydrolyzed mixture of peptides and collagen, and its efficacy is similar to that of pectin.

The pH regulator is composed of one of disodium EDTA or sodium citrate, or a mixture of the two.

Disodium EDTA and sodium citrate are pH regulators, and their respective functions are as follows:

Disodium EDTA: It is a chelating agent, which can effectively adjust the pH value of shower gel products, maintain the acid-base balance of the skin, and reduce the irritation of other chemicals to the skin.

Sodium citrate: It is an organic compound, which belongs to weak acid and strong alkali salt. It has good pH adjustment and buffering properties. It can effectively adjust the pH value of shower gel products, maintain the acid-base balance of the skin, and reduce the irritation of other chemicals to the skin. .

The flavoring agent is essence.

Fragrance is a concentrated aromatic oil that is artificially synthesized to imitate the smell of fruits and natural fragrances, and is added to body wash products to improve the smell of the product.

Described antioxidant is vitamin E.

Vitamin E is an antioxidant and a fat-soluble vitamin. Its hydrolyzed product is tocopherol, which is one of the most important antioxidants. It can resist oxidation and protect the body cells from free radicals, and keep the skin healthy.

The preparation method of this solid bath film that can be cut and used is as follows:

One, prepare PVA colloidal solution and bath solution respectively;

1) with PVA, glycerin and deionized water raw materials, and by the weight ratio of 10:1:89, be prepared into the standby colloidal solution;

2) With the selected green surfactant, skin care agent, thickener, pH regulator, flavoring agent, antioxidant and deionization as raw materials, 15-25 parts by weight of surfactant, 5-10 parts by weight of skin care agent 1-2 parts by weight of a thickener, 0.5-1 parts by weight of a pH regulator, 0.05-0.1 parts by weight of a flavoring agent, 0.05-0.1 parts by weight of an antioxidant, and 60-70 parts by weight of deionized water to prepare a bathing solution; store in an airtight container for later use;

2. Make bath film by solution casting
