Because it is a new thing, many people have never seen what a real rose dew is. Due to the trend of interests, there are many kinds of pure rose dew on the market at present, and it is difficult to distinguish between true and false. I have studied Bulgarian roses for many years. Here are some common methods for identifying pure rose dew. 1, color of pure dew: A good pure dew should be a colorless and transparent liquid. Some pure dew has a light yellow color, which is caused by processing equipment and technology. The quality is not as good as the former, and it can still be used. Pale pink or pure pink dew must be artificially colored, and it is definitely not a real pure dew. 2, the pure dew does not divide into two ways: because the real pure dew does not extract rose essential oil in the process of flower distillation, there is no such thing as the first way and the second way. Only flower water has the theory of "first way" and "second way". 3. The concentration of pure dew is high, which can form larger bubbles by shaking it back and forth in the bottle. Generally, the bubble diameter will exceed 1cm, and the flower water concentration is low, resulting in smaller bubbles. 4. It is understood that there are few manufacturers that actually produce pure dew in China, and most of them produce flower water. First of all, it depends on whether the manufacturer has a test report, a more formal website and a formal processing factory. That is to say, it depends on whether the manufacturer has the ability to produce pure rose dew. If they don't, the product is likely to be a fake. 5, to prevent fake consignment: Now the overwhelming pure dew sellers on the website, many use the picture materials of famous brand manufacturers. A considerable part of them are fake. Pay special attention to whether the sample displayed by the seller is consistent with the real thing. If it is inconsistent, it may be a fake. 6. When buying and selling pure dew, you should ask for the test report first. Some merchants are deceiving you by asking you to buy the goods first and then give the test report. 7. Besides, the price of pure dew varies greatly with different varieties. Generally, the price of real Bulgarian-Damascus 1 rose dew is more than twice as high as that of French Louvre, pingyin rose and Bitter Rose dew. Pure dew with low price may be fake. 8. The real pure dew has a strong antibacterial and bactericidal ability, and can be preserved in the natural state for more than 2 years without adding preservatives such as ethanol. Flower water needs to be preserved by adding antiseptic materials such as ethanol. Therefore, it must not be pure dew that has a strong smell of alcohol.
