When producing tinted moisturizer, the selection of dimethicone (INCI name: Dimethicone) viscosity depends on product positioning (lightweight/moisturizing), skin feel requirements (thin/silky/hydrating), and formula system (oil-in-water or water-in-oil). Below are core conclusions and detailed recommendations.

ore Recommendation Dimethyl silicone oil with a viscosity of 100–500 cSt (at 25°C) is commonly adopted in marine coatings, among which 350 cSt serves as the universal standard. For antifouling and drag-reducing coatings, 100–300 cSt is recommended; 50–200 cSt is suitable for leveling and defoaming applications; and 500–1000 cSt can be used for long-term antifouling purposes.

Silicone Oil for Freeze Dryers: Types and Common Viscosity Specifications I. Types of silicone oil for freeze dryers The primary silicone oil used in freeze dryers is dimethyl silicone oil (Polydimethylsiloxane, PDMS). Methylphenyl silicone oil may be adopted in a small number of high-end applications, yet dimethyl silicone oil remains the mainstream option for the following merits:

The viscosity selection of hydroxyl silicone oil for electrophoretic paint mainly depends on its functions in the formula, such as working as a leveling agent or modifier, and its compatibility with the system. The mainstream recommended viscosity range is 350~1000 cSt (mPa·s at 25°C). For special applications, the viscosity can be adjusted to 100~350 cSt or 1000~5000 cSt.

Amino silicone emulsion is the preferred and mainstream auxiliary for enhancing softness and smoothness of pillow wadding including spray-bonded cotton, hollow polyester filling cotton and toy stuffing cotton. It features excellent applicability and serves as a standard solution for the finishing of home textile filling cotton. However, it is necessary to select the proper silicone type and control the amine value and processing parameters. Wrong selection will result in yellowing, cotton agglomeration and collapse, as well as decreased bulkiness.

Recommended Silicone Selection for Silicone Blended with MTMS in Ceramic Coatings Priority recommendation: hydroxyl-terminated modified polydimethylsiloxane (hydroxyl silicone oil); methyl hydrogen silicone oil as alternative option. The standard applicable viscosity ranges from 350 to 1000 cSt, with customized options of 100–350 cSt or 1000–5000 cSt for special formulation requirements.

Add a small amount of polydimethylsiloxane to varnish. It mainly delivers excellent leveling, slip, defoaming, anti-blocking and hydrophobic effects. However, excessive dosage will cause gloss loss and compromise recoatability and adhesion. Viscosity and addition amount must be strictly controlled.

Combined with the defoaming application for vegetable oil, here is the detailed introduction of food-grade dimethyl silicone oil (E900), including viscosity selection, dosage, process parameters and troubleshooting.

For eyelash fiber drawing with water dilution, low viscosity silicone oil emulsion is the optimal choice. Pure high viscosity silicone oil tends to cause caking and fiber sticking, which is not recommended.
