AI Technical Summary

Problems solved by technology

However, due to its hydrophobicity, silicone oil is difficult to disperse in the water phase, and if it is directly applied to hair fibers, the hand feeling, fastness and elasticity are not ideal. Therefore, it needs to be prepared into a silicone oil emulsion in the market before it can be applied.
However, high-viscosity methyl silicone oil has strong viscosity and is difficult to emulsify, so it is difficult to meet the needs of high-viscosity silicone oil emulsion in the market
[0004] Usually, in order to emulsify high-viscosity silicone oil, a large amount of emulsifier needs to be added, and mechanical emulsification is used to stir and disperse for a long time. The current emulsion preparation method generally takes 6 hours or even longer to form a uniform emulsion. The emulsion prepared by this method usually has poor particle size dispersion and is unstable, especially during high-temperature storage, it is prone to demulsification, oil floating, and delamination.

The batch time is 10h, which is beneficial to process and industrial scale preparation and has a good practical application prospect.

Description

technical field [0001] The invention belongs to the technical field of methyl silicone oil emulsion, in particular to a kind of methyl silicone oil emulsion and a manufacturing method thereof. Background technique [0002] Silicone oil is a colorless, odorless, non-toxic and non-irritating liquid with good chemical stability, heat and cold resistance, weather resistance, hydrophobicity, lubricity, high refractive index and low surface tension. After emulsifying silicone oil to make silicone oil emulsion, it can be widely used in personal care products, textiles, and surface treatment. [0003] Simethicone has good smoothness, water repellency, breathability, UV resistance and silky touch, and can be used in hair care products. High-viscosity silicone oil has become an important additive in the personal care industry due to its good softness, hydrophobicity and wettability, and the small particle size emulsion made of high-viscosity methyl silicone oil only needs a small amo...
