What You'll Learn
Solubilizers maintain viscosity
Solubilizers are a crucial component in the creation of beauty and skincare products, such as Agilex's natural fragrances. They serve as emulsifiers, enabling the combination of oil-based fragrances or essential oils with water-based formulations. This process is known as solubilization, and it helps maintain the viscosity, or thickness, of the final product.
The role of solubilizers in viscosity maintenance is twofold. Firstly, they prevent the separation of oils and fragrances within the product, ensuring a clear and consistent appearance. This is achieved through the dispersion of oils throughout the water-based mixture, creating a stable and homogenous solution. Without solubilizers, the oils and fragrances would separate, leading to an uneven and cloudy product with an undesirable texture and reduced effectiveness.
Secondly, solubilizers allow for precise control over the viscosity of the product. By adjusting the ratio of solubilizer to fragrance or essential oil, formulators can fine-tune the thickness of their creations. A higher ratio of solubilizer to oil will result in a thinner product, while a lower ratio will produce a thicker consistency. This flexibility is especially important when developing products with specific viscosity requirements, such as lotions, creams, or shampoos.
Polysorbate 20, a widely used solubilizer in the cosmetics and pharmaceuticals industries, is renowned for its viscosity-modifying capabilities. It is effective at maintaining the clarity and consistency of products, ensuring they meet the highest standards. The recommended ratio of Polysorbate 20 to fragrance or essential oil is typically 1:1, although this may vary depending on the specific oil used.
In addition to maintaining viscosity, solubilizers offer other benefits. They enhance the stability of products, preventing oxidation and degradation, thereby extending their shelf life. Solubilizers also improve the spreadability of liquids and enhance the performance and texture of formulations. Overall, solubilizers are essential in creating high-quality, effective, and aesthetically pleasing beauty and skincare products, ensuring a seamless fusion of functionality and sensory experience.

Solubilized fragrances are more potent
Solubilized fragrances are also advantageous because they can be added to bases without compromising their thickness, or viscosity. This is especially important in cosmetic and pharmaceutical products, where a change in viscosity can affect the consumer experience and the product's effectiveness. For example, a hand cream that is too runny may be less appealing to consumers, and a lotion that is too thick may not be easily absorbed by the skin.
A solubilizer is an ingredient that makes fragrance or essential oils dissolvable in water. This is achieved by mixing the fragrance or essential oil with a solubilizer at the correct ratio, which is generally within the range of 1:1 to 5:1 (solubilizer: fragrance/essential oil). The correct ratio will result in a clear mixture, and it may take some experimentation to get this right. For example, citrus oils are generally more difficult to solubilize, so a higher ratio of 3:1 or higher is recommended.
There are many different types of solubilizers available, and they can be derived from natural or synthetic sources. Polysorbate 20 is a standard solubilizer in the cosmetics and pharmaceuticals industries, and it has been used for decades with a good safety profile. It is derived from both natural and synthetic sources and generally has a 1:1 ratio with fragrance or essential oils, making it a cost-effective option. Another example of a natural solubilizer is Symbio®solv XC, which is a proprietary blend with the INCI name: Caprylyl/Capryl Wheat Bran/Straw Glycosides; Aqua; Fusel Wheat Bran/Straw Glycosides; Polyglyceryl-5 Oleate; Sodium Cocoyl Glutamate; Glyceryl Caprylate. This natural solubilizer has been found to be very effective and affordable, however, as it is a PEG-derivative, it is not used in natural cosmetics.

Polysorbate 20 is a standard solubilizer
Solubilizers are used to incorporate fragrance and essential oils into products without compromising their viscosity. Solubilized fragrances and essential oils are more potent, less likely to oxidize, and less likely to degrade over time. Polysorbate 20 is a standard solubilizer in the cosmetics and pharmaceuticals industries. It is a non-ionic surfactant formed by the ethoxylation of sorbitan monolaurate. Its stability and relative non-toxicity make it suitable for use in various applications, including as a detergent, emulsifier, and wetting agent.
Polysorbate 20 has a broad range of applications in biological techniques and sciences. For example, it is used as a washing agent in immunoassays such as Western blots and ELISAs, where it helps prevent non-specific antibody binding. It is also used to stabilize emulsions and suspensions in pharmaceutical applications and as a wetting agent in rubber balers in the elastomer industry. In addition, polysorbate 20 is a common ingredient in baby wipes and is used by philatelists to remove stamps from envelopes without damaging them.
The correct ratio of solubilizer to fragrance or essential oil generally falls within the range of 1:1 to 5:1 and may vary depending on the specific solubilizer and oil being used. The ideal ratio will result in a clear mixture. If the solution turns milky, a higher ratio of solubilizer to oil is required. Gently stirring the mixture can help reduce bubble formation and improve clarity.
Polysorbate 20 is a cost-effective solubilizer option, typically requiring a 1:1 ratio with the fragrance or essential oil. It has a long history of use, with safety studies dating back to the 1980s. While it is a standard solubilizer, it is important to note that it is not suitable for natural cosmetics due to being a PEG-derivative. However, there are natural solubilizer options available, such as Symbio®solv XC, which can be used as an alternative.
