PASTE-LIKE SILICONE COMPOSITION, METHOD FOR PRODUCING THE SAME, AND COSMETICS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18576185 titled 'PASTE-LIKE SILICONE COMPOSITION, METHOD FOR PRODUCING THE SAME, AND COSMETICS
Simplified Explanation: The patent application describes a paste-like silicone composition containing crosslinked organopolysiloxane and oil in a liquid state at 25°C. The composition includes specific types of organohydrogenpolysiloxane and alkenyl group-containing organopolysiloxane, with low levels of certain cyclic siloxanes.
- The composition includes a hydrosilylated reaction product of organohydrogenpolysiloxane and alkenyl group-containing organopolysiloxane.
- Cyclic siloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane are present in very low amounts.
- The composition remains stable over time with minimal changes such as plasticization and emits less odor.
Potential Applications: 1. Sealants and adhesives 2. Lubricants 3. Coatings and paints
Problems Solved: 1. Stability of silicone compositions over time 2. Minimization of unpleasant odors 3. Control of plasticization in silicone products
Benefits: 1. Enhanced stability 2. Reduced odor emission 3. Improved performance in various applications
Commercial Applications: The technology can be utilized in industries such as construction, automotive, and electronics for the production of sealants, lubricants, and coatings.
Questions about Silicone Composition: 1. How does the low content of cyclic siloxanes contribute to the stability of the composition? 2. What are the specific applications where this paste-like silicone composition would be most beneficial?
Frequently Updated Research: Ongoing research may focus on further optimizing the composition for specific industrial applications and exploring additional uses for the technology.
Original Abstract Submitted
A paste-like silicone composition includes (A) crosslinked organopolysiloxane and (B) oil in a liquid state at 25° C. The component (A) includes a hydrosilylated reaction product of (A-1) organohydrogenpolysiloxane having at least two hydrogen atoms bonded to a silicon atom per molecule, and (A-2) alkenyl group-containing organopolysiloxane having at least two alkenyl groups having 2 to 10 carbon atoms and being bonded to a silicon atom per molecule. Octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane contained in the paste-like silicone composition are each less than 2,000 ppm. It is therefore possible for a stable paste-like silicone composition that has small changes over time such as plasticization return and emit less uncomfortable odor.
