Solubilizers are widely used in cosmetic and personal care products that assist in incorporating hydrophobic substances such as essential oils or fragrance oils into aqueous formulations. They play an important role in keeping the final consumer product clear and preventing separation over time. Sounds easy enough, but in practice it is very difficult. Ask any perfume manufacturer and they will tell you that clarity is as important as the aroma. But why is transparency important?
It turns out that clarity and transparency is one of the key attributes consumers look for when selecting a perfume or other fragrance product. According to Mintel, the average price for an Eau de Parfum in the US and Europe is around $80 for a 50 ml bottle. At that price point, consumers are looking for nothing less than perfection. In addition, they want to be sure the appearance stays the same over time—and don’t forget the packaging. Perfume manufacturers spend a great deal of time finding the clearest glass to use. Bottle line, clarity reigns supreme. If you want to add an additional level of complexity, skip using alcohol.
Solubilizers in Cleansers
Solubilizers that are used in facial cleansers play a different role.
Cleansers are made up of micelles that are small particles of surfactant suspended in water. Micelles are attracted to dirt and oil, so they are able to draw out impurities. The surfactant present in the cleanser product has to be soft and non-irritant for the skin while keeping efficiency in makeup removal.
Some cleansers, such as micellar water products, are formulated to be very clear, hence the use of water in its description. The transparency can only be achieved by making microemulsions with the right solubilizer.
Designing an Efficient Solubilizer with Nature in Mind – Natpure Sol Crystal
Solubilisant LRI is widely considered the Gold Standard of solubilizers and is used in applications where either the essential oil or other non-polar ingredient(s) is difficult to incorporate without the final product appearing hazy. Solubilisant LRI is also used in applications where formulators are looking to minimize or eliminate the use of alcohol, which can dry the skin. Now, consumers and the brands that cater to them, are looking for natural solubilizers, and Sensient has innovated the answer. Natpure Sol Crystal is a patented, 91% naturally derived solubilizer designed to be used to formulate personal care products that highlight naturality. It also allows formulators that ability to reduce, or even eliminate alcohol in their products. Its low viscosity makes it easy to use. In addition, it is environmentally friendly (biodegradable and non-ecotoxic) and non-irritant for the skin.
