- the mixing ratio of a1) and (a2) was compared with the detergency of Pharmaceutical Example 9 having a mixing ratio of 5: 5.
- the pharmaceutical example 9 adopted as the comparative standard is the product in which the medicinal ingredient and the thickener are added to the pharmaceutical example 4 confirmed to show high detergency in the example 1, and has the same high detergency as the pharmaceutical example 4. Show sex.
- ⁇ Evaluation method of detergency> 15 ⁇ L of the pharmaceutical product was spread on the back of each panelist's hand to a diameter of about 25 mm, and dried for 5 minutes or more. After the film had dried, it was gently rubbed for 30 seconds using a body wipe and evaluated according to the following criteria and scored (n 4).
- composition of each pharmaceutical example and the evaluation by each panelist are shown in the table below.
- the detergency of the preparation (formulation example 5) having a ratio of the polymers (a1) and (a2) of 9: 1 was not as high as that of the preparation example 9, but the required detergency standard is Was satisfied.
- the formulation (formulation example 6) having a ratio of the polymers (a1) and (a2) of 8: 2 higher detergency was observed as compared with the formulation example 5, and the ratio of the polymers (a1) and (a2) was 7: 3.
- the pharmaceutical product (formal example 7) and the 6: 4 pharmaceutical example (formal example 8) showed the same detergency as the 5: 5 pharmaceutical example 9.
- Example 3 As the polymer, a preparation containing only the polymer (a1) or the polymers (a1) and (a2) in a ratio of 7: 3 or 5: 5 was prepared, and the friction resistance was evaluated according to the following criteria. ⁇ Evaluation of abrasion resistance> The mass (A) of the slide glass is measured. Apply 100 ⁇ L of the pharmaceutical product evenly to the entire surface of the slide glass using a spatula, and dry in a mini jet oven set at 30 ° C. for 5 minutes. Then, the slide glass is taken out from the mini jet oven and its mass (B) is measured.
- a dry paper towel is placed on the surface coated with the formulation of the slide glass, a weight of 100 g is placed on the weight, and the slide glass is wiped 20 times so that a uniform force is applied to the entire slide glass.
- the residual ratio of the pharmaceutical product after wiping is calculated from each mass by the following formula. Repeat the test 3 times to determine the mean and standard deviation of the residual rate of the drug.
- Table 5 shows the composition of each pharmaceutical product and the evaluation of abrasion resistance.
- the pharmaceutical product containing the product (Pharmaceutical Example 12) showed high abrasion resistance. From this, it was confirmed that the composition containing the polymers (a1) and (a2) was excellent in detergency, but showed high resistance to friction, and was difficult to remove from the skin.
- Example 4 A preparation in which the amount of the plasticizer (DID) is changed is prepared, and the cleaning property and the friction resistance are evaluated by using the cleaning property evaluation method described in Example 2 and the friction resistance evaluation method described in Example 3. The sex was evaluated. Table 6 shows the composition and evaluation results of each pharmaceutical product. “Cannot be evaluated” in Table 6 indicates that it was difficult to evaluate because the appearance of film residue during washing was different from that of Pharmaceutical Example 9.
- the friction resistance was good for all the formulations.
- all the formulations satisfy the required detergency criteria, and in particular, the detergency of the formulations 16 to 21 in which the plasticizer is 3 to 10% by weight is good.
- the film formation time tended to be shorter (quick-drying increased), but in the preparation example 22 containing 20% by weight of the plasticizer, a film was formed immediately when applied to the skin. , It was difficult to form a uniform film.
- Example 5 A pharmaceutical product in which the type of plasticizer was changed was prepared, and the detergency and abrasion resistance were evaluated in the same manner as in Example 4. Table 7 shows the composition and evaluation results of each pharmaceutical product.
- Example 6 A pharmaceutical product in which the amount of the surfactant (PS65) was changed was prepared, and the detergency and abrasion resistance were evaluated in the same manner as in Example 4. Table 8 shows the composition and evaluation results of each pharmaceutical product.
- the detergency of the pharmaceutical product example 30 containing no surfactant was not as high as that of the pharmaceutical product example 9, but it was confirmed that the required detergency criteria were satisfied.
- Pharmaceutical examples 32 to 36 containing 1% by weight or more of the surfactant showed good detergency.
- Example 7 A pharmaceutical product in which the type of surfactant was changed was prepared, and the detergency and abrasion resistance were evaluated in the same manner as in Example 4. The composition and evaluation results of each pharmaceutical product are shown in Tables 9 and 10.
- the pharmaceutical examples 37 to 43 containing the nonionic surfactant showed good detergency and abrasion resistance.
- the friction resistance was also good when an anionic surfactant or an amphoteric surfactant was used.
- the detergency as shown in Table 10 as “not evaluationable”, when an anionic surfactant was used, the film was melted off during cleaning, so it was difficult to determine whether the film could be washed off from the skin. Even when amphoteric tenside agents were used, panelists 1 and 2 were judged to be unevaluable.
- Example 46 and Example 47 the score 4 (no remaining) is 2 and the score 3 (30% or less remaining) is 1, and there is no problem in detergency even when an amphoteric tenside agent is used.
- the formulation was ready. From the results of Example 7, it was found that when a nonionic surfactant or an amphoteric surfactant was used as the surfactant, it was easy to visually confirm the film removal.
- Example 8 Preparations in which the amounts of the polymers (a1) and (a2) were changed were prepared, and the detergency and abrasion resistance were evaluated in the same manner as in Example 4. Table 11 shows the composition and evaluation results of each pharmaceutical product.
- the pharmaceutical example 48 having a total amount of the polymers (a1) and (a2) of 1.2% by weight had lower abrasion resistance than the other pharmaceuticals.
- the pharmaceutical examples 49 to 58 in which the total amount of the polymers (a1) and (a2) was 2.4% by weight to 24% by weight showed good detergency and abrasion resistance.

各ポリマー及び精製水を秤取し、及び任意で、可塑剤/界面活性剤/増粘剤/薬効成分を加え、均一になるまで撹拌した。各製剤例(製剤例1~58)の組成は、表2,4~11に示す通りである(表中の各成分の数値は重量%を示す)。表に示すポリマー及び界面活性剤の含有量は、固形分の含有量であり、表に示す精製水の含有量は、ポリマー及び/又は界面活性剤の水性懸濁液(水分散液)又は水溶液を用いた場合は、水性懸濁液又は水溶液中に含まれる水と、添加した精製水の合計量である。
製剤15μLを各パネラーの手の甲に直径約25mmサイズに塗り広げて、皮膜を形成し、皮膜の視認性について評価した。
また、皮膜が完全に乾燥した後、37℃のお湯に手を30秒間浸漬し、お湯から手を出した後、皮膜を2分間擦り、下記の洗浄性2項目をそれぞれ評価して、スコア化した(洗浄性及び視認性のいずれも、パネラーは14名)。表2に示す合計スコアは、各スコアの数値とそのスコアの判定人数とを掛けて得られる値を合計したものである。
ポリマー(a1)と(a2)の混合割合を、9:1、8:2、7:3、6:4とした製剤(製剤例5~8)を調製し、それらの洗浄性を、ポリマー(a1)と(a2)の混合割合が5:5の製剤例9の洗浄性と比較した。比較基準として採用した製剤例9は、実施例1において高い洗浄性を示すことが確認された製剤例4に、薬効成分及び増粘剤を加えたものであり、製剤例4と同様の高い洗浄性を示す。
製剤15μLを各パネラーの手の甲に直径約25mmサイズに塗り広げ、5分以上乾燥した。
皮膜が乾燥した後、身体用の拭き取りシートを用いて、30秒間優しくこすり、以下の基準で評価してスコア化した(n=4)。
ポリマーとして、ポリマー(a1)のみ、又はポリマー(a1)と(a2)を7:3もしくは5:5の割合で含む製剤を調製し、以下の基準で耐摩擦性を評価した。
<耐摩擦性の評価>
スライドガラスの質量(A)を測定する。
製剤100μLを、へらを用いてスライドガラスの全面に均一に塗布し、30℃に設定したミニジェットオーブンで5分間乾燥させる。その後、ミニジェットオーブンからスライドガラスを取り出し、その質量(B)を測定する。次に、スライドガラスの製剤塗布面に乾いたペーパータオルを載せ、その上から100gの重りを載せて、スライドガラス全体に均一に力がかかるように20回拭き取った後、スライドガラスの質量(C)を測定する。以下の式により、各質量から拭き取り後の製剤残存率を算出する。試験を3回繰り返し、製剤残存率の平均値及び標準偏差を求める。
可塑剤(DID)の量を変更した製剤を調製し、実施例2に記載の洗浄性の評価方法、及び、実施例3に記載の耐摩擦性の評価方法を用いて、洗浄性及び耐摩擦性を評価した。各製剤の組成と評価結果を表6に示す。表6中の「評価不可」は、製剤例9とは洗浄時の皮膜カスの出方が異なるため、評価が困難であったことを示す。
表10に示すように、陰イオン性界面活性剤又は両性界面活性剤を使用した場合も、耐摩擦性は良好であった。洗浄性については、表10に「評価不可」と示すように、陰イオン性界面活性剤を使用した場合、洗浄時に皮膜が溶け落ちるため、皮膜を皮膚から洗い流せたかどうかの判断が難しかった。両性界面活性剤を使用した場合も、パネラー1及び2は、評価不可と判断したが、さらに、表1に示した洗浄性(皮膚の後残り)に関する試験をパネラー3名について実施した結果、製剤例46及び製剤例47では、スコア4(残りなし)が2名、スコア3(3割以下残っている)が1名であり、両性界面活性剤を使用した場合も、洗浄性に問題のない製剤が調製可能であった。
実施例7の結果から、界面活性剤として非イオン性界面活性剤又は両性界面活性剤を使用した場合、目視による皮膜除去の確認が容易になることが分かった。
