Description

Water Soluble Sheet Soap

technical field

The invention relates to a water-soluble membrane soap, in particular to a water-soluble membrane soap with functions of cleaning, sterilization and skin care.

Background technique

At present, scented soap has been widely used in people's daily life as a kind of cleaning article, but, there are many inconvenient parts when the scented soap of traditional form is used in some specific occasions, for example, when going out to travel, On trains, automobiles, ships and airplanes, after the self-provided soap is used up, the soap is damp and sticky, making it difficult to store it again. Some public places, such as public toilets in restaurants, hotels and hospitals, have public soaps, but many people are reluctant to use them or rarely use them due to fear of cross-infection. Before the present invention was proposed, some inventors had proposed other forms of cleaning supplies that were different from traditional soaps, such as hand sanitizers and hand-washing films, but hand sanitizers also had the disadvantage of being inconvenient to carry when used. Simultaneously, the packaging of hand sanitizer also has the possibility of cross-infection when many people use it in public places; For example, when the humidity is high, the product will become soft and sticky due to the film-forming material absorbing moisture in the air, which is not easy to use and store, and in a particularly dry environment, the film will become brittle and broken.

Contents of the invention

The purpose of the present invention is to propose a water-soluble membrane soap with new features of portability, one-time use, prevention of cross-infection, sterilization and skin care while maintaining various functions of traditional soaps.

To achieve the above object, the present invention takes the following technical solutions:

The invention discloses a water-soluble membrane soap, which is made of soap raw materials and water-soluble film-forming material, wherein the water-soluble film-forming material includes pullulan.

The selected water-soluble film-forming material of the present invention is pullulan, and pullulan is a kind of novel polysaccharide, and this polysaccharide is a kind of amylopectin, and this amylopectin is the derivative of natural polysaccharide, and it is Produced by direct fermentation of starch hydrolyzate, sucrose or other sugars. Extracellular polysaccharides produced by the action of pullulanase on polysaccharides. The basic structure is maltotriose, that is, glucose is combined with a-1, 4 bonds to form maltotriose, and the two ends are combined with other maltotriose with a-1, 6 bonds to form a high molecular polysaccharide. The ratio of a-1,4 bonds to a-1,6 bonds is 2:1. The degree of polymerization (D.P.) is 100-5000. The average molecular weight is 40,000-2 million, and the molecular weight varies with the fermentation production conditions. The pullulan P102 produced by Hayashibara Institute of Biochemistry in Japan meets the technical requirements of the present invention. This polysaccharide has the following characteristics and is suitable for making film products:

1. Toxicity: The semi-lethal dose LD50 limit of polysaccharide is 15 g/kg. Polysaccharide will not cause any biological toxicity and abnormal state. It is very safe to be used in cosmetics and cleaning products.

2. Environmental protection: Polysaccharides can be decomposed under the action of microbial enzymes and disappear in nature without causing environmental pollution. The COD value of polysaccharide is twice as low as that of polyvinyl alcohol.

3. Solubility: The solubility of polysaccharides in water is theoretically unlimited, and both cold and hot water have good solubility. The dissolution rate is faster than other polymer water-soluble substances. The solution is neutral, not ionized, and not crystallized.

4. Miscibility with water-soluble polymer substances: polysaccharides can be mixed with carboxymethyl cellulose, carboxyethyl cellulose, sodium alginate, polyacrylic acid, polyacrylamide, polyvinylpyrrolidone, starch, animal glue, polyvinyl alcohol , Polyoxyethylene is very good miscibility.

5. Viscosity: The viscosity of polysaccharides is much lower than that of other polysaccharides. The viscosity of aqueous solution increases with the increase of solution concentration, but the change is much smaller than that of other polysaccharides.

6. Moisture absorption: polysaccharides basically do not absorb moisture when the relative humidity is below 70%, and do not glue together.

7. Plasticity: 5-20% polysaccharide aqueous solution is coated on glass plates and metal plates to easily form films of different thicknesses. Simple polysaccharide films are colorless and transparent, with strong elasticity, but poor flexibility and ductility. Add Appropriate plasticizers or mixed with other polymer materials can improve flexibility and ductility.

8. Film properties: polysaccharide film has good transparency, strong elasticity, strong water solubility, is 3 times faster than polyvinyl alcohol, and has a small surface friction coefficient. The most special property is that various gases are almost completely impermeable to the film. Only polyvinyl alcohol can compare.
