![]() ![]() There are many examples of emulsions in our daily life. To emulsify means to combine two ingredients together which do not ordinarily mix easily. The lowered surface energy might also mean that the emulsion creates more wetting, which might not always be wanted. Emulsifications can be a thick liquid or a creamy semi-solid. An emulsion can be defined as a colloid consisting of two or more non-homogenous types of liquids wherein one of the liquids contains the dispersion of the different forms of liquids. For cases in which it is (cosmetically) needed/wanted to have a perfectly clear liquid, it can be difficult to achieve this with enough emulsifier in the mixture. Downside of emulsionsĪn emulsion has the property that it lowers the surface tension of the water and often turns it slightly cloudy. QD’s carry a mixture that is similar to paste wax, but thinner and with less wax-like ingredients. This basis makes it very easy to dilute the QD, and thus making it easier to create a concentrated version of the product, which is more economical and favorable for the customer. Many QD’s are emulsion of wax, oils and a water-like carrier. ![]() The emulsifier in the soap will make it possible for the water molecules to cling to the oil molecules, creating an emulsion of grease and water.Īnother popular formulation for an emulsion is a quick detailer. Soap turns water with a high surface tension into a solution with a very low surface tension, making it capable to interact will hydrophobic molecules. This means that the water has to be capable of mixing with the water, otherwise it will still be very difficult to remove. When you want to wash your dishes, you need to remove oil and other grim from the plates and pans. When do you need an emulsionĪn emulsion can be usefull for several reasons. This creates 2 different molecules, sticking together thanks to the emlusifier. The hydrophobic head will stick to the oil, the hydrophilic tail will stick to the water. This gives it the capacity to cling to the oil molecule and also with the water molecule. An emulsion is another substance that is both hydrophobic and hydrophilic. When oil molecules come into contact with water molecules, the molecules will not mix with each other. Oils are naturally hydrophobic, meaning they act as if they repell water. The mixture you end up with is reffered to as an emulsion. If you want to combine these you will need something that holds them together. In some cases, oil has certain characteristics that you want to use, but water also has some useful properties. ![]()
