PEG-10 Dimethicone: The key to smooth and homogeneous pigment dispersion
Achieving uniform and stable dispersion of pigments such as titanium dioxide, zinc oxide, iron oxides, and pigments is essential for consistent color, coverage, and texture. One of the key ingredients enabling this is PEG-10 Dimethicone (LK-1083) with a lower Hydrophilic-Lipophilic Balance (HLB). This silicone based dispersant is highly effective in bridging the gap between hydrophobic pigments and water or hydrophilic pigments and silicone based formulations, making it a popular choice in sunscreens, foundations, BB creams, and other pigmented personal care products.
About PEG-10 Dimethicone (LK-1083):
PEG-10 Dimethicone is a polyether-modified silicone, this structure gives the molecule both hydrophilic (PEG) and lipophilic (dimethicone) characteristics, allowing it to interact with both oil and water based components. In versions with a low HLB, the molecule exhibits stronger affinity toward oil phases, enhancing its compatibility with hydrophobic pigments and oil compatible solvents commonly used in personal care and cosmetic formulations.
- Improved Pigment Dispersion: The lower HLB value enhances the ability of PEG-10 Dimethicone facilitates uniform dispersion in oils or silicone elastomers.
- Enhanced Product Stability: By preventing re-agglomeration, it contributes to long-term suspension of pigments and minimizes settling or separation in emulsions.
- Better Aesthetic Performance: Products with well-dispersed pigments have smoother skin feel, better color fidelity, and more even application.
Zinc oxide dispersion with PEG-10 Dimethicone: Case Study
Next-Gen Dispersion: PEG-10 Dimethicone Elevates Zinc Oxide Performance
Zinc oxide dispersion compared with PEG 10 Dimethicone (LK-1083) and without PEG-10 Dimethicone. LK-1083 at 6-10% to Zinc oxide give desirable dispersion, improving properties live lowering white cast, imparting non greasy and non-tacky feel and giving even coverage. Below graph and photo shows how LK-1083 can modify dispersion.
Key benefits of LK-1083 in Zinc oxide dispersion:
- Zinc oxide dispersion with LK-1083 shows reduced white cast.
- It feels less tacky on the skin.
- The texture is less greasy.
- It provides more even coverage.
- Spreadability is noticeably improved.
