Preparative Example 1 of Pumping Type Toothpaste Composition

(4) (1) Ingredients and Composition Ratio

(5) Toothpaste compositions of examples and comparative examples were prepared by the ingredients and composition ratios shown in the following Table 1. Other ingredients except for an abrasive such as silica or the like and a pharmaceutical agent were completely dispersed for primary mixing. Here, non-aqueous ingredients, vitamin E and a flavoring were primarily mixed by adding a solubilizer, HCO40, poloxamer 407, polysorbate 20, or octyldodeceth-16 together. Next, the abrasive such as silica or the like and the pharmaceutical agent were added and were mixed under vacuum to prepare toothpaste compositions. However, Comparative example 4 not using a solubilizer was prepared without the primary mixing process.

(7) (2) Measurement of Transparency of Toothpaste

(8) For toothpaste prepared as Examples 1 to 3 and Comparative examples 1 to 6 of the above Table 1, after adding toothpaste in a thickness of 1 cm to a transparent petri dish, transparency of toothpaste was determined by readability of the word Batang font 10 points. The result was described in Table 2.

(9) In the evaluation of the readability, the case that the readability was impossible at a certain level based on reading letters correctly by a group of five evaluators was determined as opaque.

(11) In case of Comparative examples 1 to 3 containing an abrasive, they were opaque even solubilizing non-aqueous ingredients by a solubilizer, and in case of Comparative example 4, it was opaque, as there was no solubilizing process even it did not contain an abrasive.

(12) On the other hand, in case of Examples 1 to 3 which did not comprise an abrasive and comprised a solubilizer, HCO40 or poloxamer 407, toothpaste compositions in a transparent formulation could be obtained.

(13) In addition, in case of Comparative example 5 and Comparative example 6, which did not comprise an abrasive and comprised a solubilizer, but comprised polysorbate 20 or octyldoceceth-16, it was not possible to obtain a toothpaste composition in a transparent formulation.

(14) (1) Ingredients and Composition Ratio

(15) Toothpaste compositions of examples and comparative examples were prepared by the ingredients and weights shown in the following Table 3. For example, other ingredients except for an abrasive and selectively a pharmaceutical agent were primarily mixed. Then, non-aqueous ingredients, a flavoring and vitamin E were primarily mixed by adding a solubilizer, HCO40, poloxamer 407, or a mixture thereof together. Next, the abrasive such as silica or the like and selectively the pharmaceutical agent were added and were mixed under vacuum for secondary mixing to prepare toothpaste compositions. However, Comparative example 1 not using a solubilizer was prepared without the primary mixing process.

(17) (2) Comparison of Toothpaste Transparency

(18) For toothpaste prepared as Examples 1 to 3 and Comparative examples 1 to 4 of the above Table 3, after adding toothpaste in a thickness of 1 cm to a transparent petri dish, transparency of toothpaste was determined by readability of the word Batang font 10 points. The result was described in Table 4.

(19) In the evaluation of the readability, the case that the readability was impossible at a certain level based on reading letters correctly by a group of five evaluators was determined as ‘opaque’, and the case that identification of letters was possible but unclear as ‘slightly transparent’ and the case that letters could be identified without inconvenience as ‘transparent’.

(20) TABLE-US-00004 TABLE 4 Comparative Comparative Comparative Comparative Example1 Example2 Example3 example1 example2 example3 example4 transparency transparent transparent tansparent slightly opaque opaque opaque transparent

(21) Comparative example 1 of which refractive index of the abrasive was similar to that of the liquid raw material, but did not comprise a solubilizer, showed a slightly transparent level, but on the other hand, Comparative examples 2-4 of which refractive indexes of the abrasive and liquid raw material were not similar were opaque despite of comprising a solubilizer, and Examples 1-3 of which refractive indexes of the abrasive and liquid raw material were similar and solubilized non-aqueous ingredients, particularly, a flavoring by a solubilizer, were transparent. Through this, it was confirmed that the transparency of a formulation was increased, when the refractive index of an abrasive was similar to that of a liquid raw material and non-aqueous ingredients including a flavoring were solubilized by a solubilizer, in the toothpaste composition comprising an abrasive.

(22) (3) Confirmation of Refractive Indexes According to Glycerin Contents

(23) The refractive indexes according to the content of glycerin to water were shown in the FIGURE. Referring to that the refractive index of silica (Solvay, Tixosi173K) was 1.437 and the FIGURE, it was confirmed that when using silica in an amount of 14% by weight, the content of glycerin to water which could make the refractive index of the liquid raw material similar was 76%. Accordingly, it was confirmed that when using silica of 14% by weight, glycerin of 62% by weight and water of about 19% by weight, the refractive indexes between ingredients of the toothpaste composition was made similar, and therefore the transparency of the toothpaste was improved.
