Marketing Bulletin SILSOFT * ETS trisiloxane SPECIALTY FLUIDS - PERSONAL CARE INCI Name: Ethyl Trisiloxane Silsoft ETS trisiloxane is a highly volatile linear siloxane that can help provide an outstanding sensory experience. It can help formulations spread easily and rapidly and feel dry and light upon application. Silsoft ETS trisiloxane, as a multifunctional raw material, can help build personal care products that provide highly valued sensory benefits. Key Features and Typical Benefits Silsoft ETS trisiloxane has a high volatility profile that can help provide a quick rub in with a dry, light after feel. Silsoft ETS trisiloxane can usefully be formulated into pumpable compositions to help provide uniform coverage, reduce run-down of formulations and enhance sensory properties of the formulation on the skin. Silsoft ETS trisiloxane lowers the surface tension of common personal care emollients and oils, which can aid the ease of formulation spreading. Silsoft ETS trisiloxane improves pigment dispersion within the oil phase to help provide better overall coverage in color cosmetics and better uniform coverage of inorganic sunscreens. Typical Physical Properties Appearance Clear, colorless liquid Silicone, % >98 Color Pt-Co <40 Typical properties are average data and are not to be used as or to develop specifications.
Potential Applications Color Cosmetics (use level 1-20%) (1) Mascara Eye Shadow Eye Liner Lip Stick Liquid Lip Lip Liner Foundation Concealer Sunscreens (use level 1-10%) Lotion Cream Sunless Tanner (2) Skin Care (use level 1-10%) Lotion Cream Mask Hair Care (use level 1-10%) Styling Aids Low VOC Products Hair Spray (2) (1) 20% usage level is in the Mascara application only. For all other color cosmetics, it is 1-10%. (2) When considering a consumer aerosol application for any silicone-based material, regardless of the method of aerosol generation, refer to guidance, which is published by the Silicone Environmental, Health and Safety Council (SEHSC). Per this guidance, the particle size MMAD should be at least 30 μm with no more than 1% of the particles having an aerodynamic diameter of 10 μm or less to ensure that virtually all aerosol particles will be trapped in the nasopharyngeal region and very few, if any, particles will be deposited in the tracheobronchial region. A copy of this guidance is available from Momentive. Chemical Structure Chemical Name: 1,1,1,3,5,5,5-Heptamethyl-3-Ethyltrisiloxane O O Test Performance Data Figure 1: Volatility Profile of Silsoft ETS Trisiloxane Greater than Industry Standards 120 100 80 60 Cyclopentasiloxane (D5) 40 20 Octamethylcyclotetrasiloxane (D4) 0 0-20 10 20 30 40 50 60 70 80 Silsoft ETS trisiloxane t / min 40 C Residue / % Silsoft ETS trisiloxane, Octamethylcyclotetrasiloxane (D4) and Cyclopentasiloxane (D5) had their volatility profile tracked at 40 C by measuring, at 5-minute intervals, the remaining percent residue of the materials. Over the assessed time period, Silsoft ETS trisiloxane consistently had less measurable residue in comparison to D4 and D5. Silsoft ETS trisiloxane clearly demonstrates a volatility profile that is improved over the industry standards of D4 and D5. Silsoft ETS trisiloxane, by quickly evaporating without a cooling sensation, can help build formulations with an exquisite after feel that is dry and light. Si Si Si CAS # 17861-60-8 INCI Name: Ethyl Trisiloxane Physical Data Boiling Point 172 C STP Melting Point <-60 C STP Flash Point 45 C Viscosity ~1.1 mpas @ 20 C Density ~0.83 g/cm 3 Silsoft ETS trisiloxane is a linear ethyl trisiloxane (1,1,1,3,5,5,5-heptamethyl-3-ethyltrisiloxane) of low molecular weight that provides a high volatility profile and acts as a vaporizable carrier. Silsoft ETS trisiloxane is a clear colorless liquid that is easy to incorporate into personal care formulations at low processing temperatures. Typical physical property data values are averages and should not be used as specifications. Note: Test data. Actual results may vary. Page 2 of 12
Test Performance Data (continued) Figure 2: Fast Spreading and Quick Drying High Volatility Profile of Silsoft ETS Trisiloxane Can Help Control Formulation Run-Down Dicaprylyl Ether Diameter (cm) Silsoft ETS trisiloxane Cyclopentasiloxane Ambient Temperature 2 4 6 min Cyclopentasiloxane Formulation A Silsoft ETS trisiloxane Formulation B Identical sunscreen formulas, except for the addition of Silsoft ETS trisiloxane or Cyclopentasiloxane, were prepared to test the concept of formulation run-down: the tendency of formulations to run-down a vertical surface because they remain as wet fluid upon application. Formulation A and Formulation B were sprayed through a wide variety of pump diffusers to eliminate packaging influence. All formulations containing Silsoft ETS trisiloxane left minimal residue upon spraying which limits the liquid available to contribute to formulation run-down. The ability of Silsoft ETS trisiloxane to reduce formulation run-down can also contribute to an improved coverage and active deposition upon the skin. The quick evaporation of Silsoft ETS trisiloxane can lead to actives staying where deposited when initially sprayed onto the skin instead of traveling with the formulation as it runs down the skin. One drop, approximately 0.5 ml, of each material was placed onto the underside of one individuals arm. The diameter of the circle formed by the material was measured to give an indication of relative surface tension. The larger diameter for Silsoft ETS trisiloxane indicates not only a lower surface tension, but that formulations containing this raw material would spread more easily upon skin, rub-in would require less effort and offer a smooth application. The time required for the raw materials to completely dry was also measured. Silsoft ETS trisiloxane took less than half the time required for Cyclopentasiloxane. Reduced drying time implies that when Silsoft ETS trisiloxane is used in a personal care formulation, it can increase the capacity of that formulation to reduce the overall sensation of tackiness and wetness.

Test Performance Data (continued) Figure 3: Silsoft ETS Trisiloxane Can Help Provide a Differentiated Sensory Experience Cyclopentasiloxane Scored as ZERO on All Attributes NEGATIVE CONTRIBUTION POSITIVE CONTRIBUTION Zero Rub-in Speed Oiliness Dry After Feel Shine Silsoft ETS trisiloxane Isononyl Isononanoate Octododecyl Neopentanoate Dimethicone (5 cst) A sensory evaluation of Silsoft ETS trisiloxane, along with Isononyl Isononanoate, Octododecyl Neopentanoate and Dimethicone (5 cst) was completed to compare them against the sensory attributes of Cyclopentasiloxane. In the above graph, Cyclopenta siloxane rates zero on all sensory attributes, the other raw materials were rated according to their perceived value against Cyclopentasiloxane. Values to the left of the Cyclopentasiloxane zero line correlates to the product having less of this attribute and values to the right of the zero line correlates to the product having more of this attribute than Cyclopentasiloxane. This sensory evaluation clearly displays that Silsoft ETS trisiloxane had a highly differentiated attribute profile when compared against the esters, Dimethicone and Cyclopentasiloxane. Silsoft ETS trisiloxane had a faster rub in speed, while still providing a highly valued dry after feel without a greasy feel. The reduced shine attribute, along with the dry after feel, makes Silsoft ETS trisiloxane an excellent candidate to consider for foundation formulations; quick to dry, improved coverage and reduced shine.

Performance Data (continued) Figure 4: Silsoft ETS Trisiloxane, Through Surface Tension Reduction, Can Improve the Spreadability of Common Personal Care Oils Surface Tensiion dynes/cm 35 30 25 20 15 10 5 Mineral Oil Jojoba Oil Triglyceride 0 Oil Alone Silsoft ETS tisiloxane (50/50) Since Silsoft ETS trisiloxane has a low surface tension itself (17.9 dynes/cm) it has the capability to significantly reduce the surface tension of common personal care oils and emollients. With Silsoft ETS trisiloxane reducing the surface tension of these oils, formulations can be developed that will rub in more quickly, easily and also help with reducing formulation tackiness. Figure 5: Silsoft ETS Trisiloxane Can Improve Pigment Dispersion to Increase Color Coverage and Actives Deposition 8 7 6 Hegman Index 5 4 3 2 1 0 Mineral Oil / TiO2 (90/10) Mineral Oil / Cyclopentasiloxane / TiO2 (45/45/10) Mineral Oil / Silsoft ETS trisiloxane / TiO2 (45/45/10) The Hegman index measures the ability of a material to distribute pigments equally throughout a given sample. Without an even dispersion, pigments can settle within a formulation, leading to the possibility of inconsistent color coverage or poor active delivery concentrations when applied to the skin. Since Silsoft ETS trisiloxane has demonstrated the ability to improve pigment dispersion, it could improve color coverage and aid in the even deposition of actives on the skin, especially in conjunction with its ability to improve the ease of spreading.
