تقييم كيماوي لبعض من سوائل غسيل الصحون اليدوي المتوافرة في السوق المحلية و أثرها على المستهلك

الملخص EN

The present study has been used three analytical methods, one of them was suggested by this work to determine the total organic materials in hand dishwashing liquids by using UV specrophotometric at 250 nm and using ammonium oxalate as a reference material.

In this research dry weight percentage of dishwashing liquids, the charge types of organic material, and the values of the pH of 12 samples of dishwashing liquids from local market have been determined.

The pH values of dishwashing liquids have shown 6.2 and 8.97 values.

Although, the Iraqi specification specified the value of active organic material not to be lower than 20% the results have shown a disparity of values fixed on the bottles.

Values were recorded 20% for five samples, whereas for other three the value was between 5% and 15%, two samples gave values between 15% and 30%, two other samples were specified by 14% only.

The study shown that weight the percentages of total organic materials in hand dishwashing liquids gave high values, especially in seven samples ( 17.6% and 72% ) whereas in other samples dropped to 9%.
