| Summary: | We conducted the guinea pig three days repeated open patch test using the samples of three polyols (propylene glycol, 1, 3-butylene glycol and glycerin) as is and 10% in distilled water and of three hydrocarbons (liquid paraffin #72, squalane and pristane). Tests were performed in three labolatories.Comparing the mean reaction of each three laboratories based on Japanese standard, the all samples of the polyols were weak in the skin reactions and no clear differences of reactions were seen. On the other hand, hydrocarbons showed irritant reactions and the order of irritancy was pristane, liquid paraffin #72 and squalane.By the Draize standard, polyols showed slight erythema and no edema, and hydrocarbonsshowed parallel score between erythema and edema, and the irritation order of three hydrocarbons was the same as that of the Japanese standard.Though some differences were shown in the grade of reactions between three laboratories, there was shown the same order as to the irritation grade of three chemicals.
モルモットに対する3日間連続塗布試験を試験資料として多価アルコール3種 (プロピレングリコール, 1, 3-ブチレングリコールおよびグリセリン) の原体および10%水溶液, 炭化水素3種 (流動パラフィン#72, スクワランおよびプリスタン) の原体を用い, 3施設で実施した。その結果, 施設間にデータのバラツキがみられたが各施設における試験資料の刺激性順位は同一であった。3施設の平均成績で比較すると, 本邦基準による判定では多価アルコールは各試験資料とも皮膚反応は弱く, 試験資料間に明らかな刺激性の差はみられなかった。炭化水素は刺激が認められ, その程度はプリスタン>流動パラフィン>スクワランの順であった。Draize基準による判定では, 多価アルコールの場合, 紅斑と痂皮はわずかに認められる程度であり, 浮腫は全く認められなかった。炭化水素の場同, 浮腫は紅斑と痂皮の強さに応じて強くなる傾向を示した。 |
