| Abstract: | There are not complete testing standards or methods for formaldehyde in toothpastes and its raw materials till now in our country. According to related products＇ national standards and literatures, a determination method was developed： toothpastes are extracted by steam distillation, then the formaldehyde in the distilled solution is tested by using acetyl acetone colorimetry. This method eliminats the interference for the colourably because of turbidity caused by toothpaste components. It provide an easy and accurate way for the test of the formaldehyde in the toothpastes and its raw materials. |
| Keywords: | toothpaste toothpaste materials formaldehyde steam distillation acetylacetone colorimetry |
