UCON Fluids
Unique formulation additives that deliver emolliency emolli ency,, solvency solvency,, and smooth application
UCON™ Fluids are a series of copolymers of ethylene oxide and propylene oxide, or of polyethylene glycol and polypropylene glycol. These moderate-viscosity fluids provide emolliency, solvency, and slip in skin lotions, eye makeup removers, antiperspirants, and deodorants. At the same time, they can offer a number of other benefits, such as the ability to efficiently wet pigments, to generate heat upon application, or to control viscosity in shampoo systems. When you want to make a product feel soft and apply smoothly, or when difficult-to-solubilize ingredients are involved, look to UCON Fluids for unique sensory and physical contributions.

UCON Fluid AP Gives Antiperspirants Outstanding Emolliency and Smooth Application For roll-o roll-on, n, stic stick, k, soft solid, solid, and aeroso aerosoll antipersp antiperspirant irant syste systems, ms, UCO UCON N Fluid AP gives a remarka remarkably bly soft, smooth emollient emollient feel. It suspends antipersp antiperspirant irant actives and assists their spreadability.
An ideal alternative to isopropyl myristate
If you’re looking for alternatives to isopropyl myristate to avoid the acne and other allergic reactions this ingredient can cause, UCON Fluid AP is the right right choice. Clinical tests demonstrate demonstrate that UCON Fluid AP can be substituted for isopropyl myristate without any change in antiperspirant efficacy. In aerosol systems, systems, stability tests show UCON UCON Fluid AP provides more stable suspension of chlorohydrol salts than isopropyl myristate. In Dew Point Hygrometer Hygrometer testing, UCON Fluid AP shows approximately approximately 25% moisture transmission reduction—very similar to isopropyl myristate.

Salicylic Acid Study Demonstrates Outstanding Solubility Properties of UCON Fluids This study was designed to model the solubility of salicylic acid in various materials materia ls used in skin care formulations. The results show that UCON Fluids, Fluids, typically specified specified for emolliency and humectancy, humectancy, also offer unusually good solvency properties. Salicylic acid is a common active used in skin care formulations like anti-acne treatment treatme nt products. Since it is recognized as a difficult material to solubilize properly,, salicylic acid provides a good reference properly reference point for comparing the the abilities of various materials to dissolve different formulation ingredients and hold them in solution. As seen in the photomicrographs photomicrographs in Figures Figures 2 and 3, UCON Fluids are are excellent solvents for this difficult-to-dissolve material.

Pigmented Systems Get More Efficient Wetting and Spreading UCON Fluids can help you meet the challenge challenge of wetting pigments, pigments, whether hydrophobicc or hydrophilic, over a wide range of pigment particle hydrophobi particle sizes. In formulating pigmented pigmented products, products, two key points points of performance are wet points and flow points. points. The wet point gives gives an indication of wetting efficiency and the pigment dispersion uniformity uniformity.. The lower the wet point, the less oil is necessary necessary to “wet” out the pigment. pigment. The flow point point provides an an idea of the ease of spreading and uniformity uniformity of coverage. The lower the flow point, the lower the level of oil needed for internal lubrication lubrication of pigments.
Excellent wetting power
Tests conducted with a variety of commercial titanium dioxide products (See Table 8) demonstrate the excellent wetting properties of UCON Fluid AP compared to mineral oil and caprylic/capric triglyceride. As seen in Figure 4, UCON Fluid AP provides provides far more efficient efficient wetting of of TiO2. In many cases, UCON Fluid Fluid AP provided provided particle particle wetting wetting at half half or even a third the level level of mineral oil required, required, and significantly significantly less than caprylic/capric triglyceride.

Even better flow properties
Using the same set of TiO 2 materia materials, ls, we conducted conducted flow point tests tests with UCON UCO N Fluid AP, AP, mine mineral ral oil, cap caprylic/ rylic/capr capric ic triglyce triglyceride, ride, and polyisob polyisobuten utene. e. Figure 5 shows the remarkable efficiency of UCON Fluid AP at achieving good flow of pigment particles compared to the other test materials. By these comparisons, comparisons, UCON Fluid AP stands stands out in its superb lubricating lubricating qualities. The quantities of UCON UCON Fluid AP required to achieve achieve good flow are close to those required for good wetting (compare Figures 4 and 5). For mineral oil and caprylic/capric caprylic/capric triglyceride, triglyceride, significantl significantlyy higher concentrations are required for good flow.

The three shampoo formulations detailed in Table 9 were developed to evaluate the viscosity-controlling performance of UCON Fluids in systems relying on different viscosity-building techniques. These include a conventional salt/surfactant salt/surfact ant combination, one using a cellulosic thickener (CELLOSIZE (CELLOSIZETM QP-4400 H), H), and another relying on surfactants surfactants alone.

As shown in Figure 6, UCON Fluid 50-HB-660 50-HB-660 very efficiently efficiently reduces the viscosity of the surfactant system formulation (T73-185-1) at low use levels. It had no viscosity-lowering viscosity-lowering effect on the cellulosic-thickened cellulosic-thickened system, system, and created only a minor viscosity reduction in the salt/surfactant system. Other products within the UCON Fluid family may also be good candidates for shampoo viscosity viscosity control. Figure 7 compares viscosity-reduct viscosity-reduction ion profiles for UCON Fluid 50-HB-660 and UCON Fluid 50-HB-3520 in the surfactant system formulation. formulation. While UCON Fluid 50-HB-3520 50-HB-3520 is a more efficient viscosity-lowering viscosity-l owering additive, additive, both UCON Fluids generate dramatic viscosity viscosity reduction at at very low low concentrations. concentrations. And both follow similar viscosityreducing profiles across the range of use levels tested for the formulation.
