Problems solved by technology

But on the other hand, 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 feel, fastness and elasticity are not ideal. Therefore, it needs to be prepared into a silicone oil emulsion in the market before it can be used.
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
[0003] In conventional emulsions, due to the small particle size of the emulsion, the chance of attachment to the hair is greatly increased, and the chance of washing off is reduced. After repeated use, the degree of accumulation on the hair is high, and it is easy to make the hair astringent and hard.

Embodiment 1

[0026] Add 60 parts of dimethicone with a viscosity of 60000cs to the high-efficiency shearing emulsification equipment, add 4 parts of betaine, then add 10 parts of water, stir evenly, add 24 parts of dilution water, after stirring evenly, add 1 1 part of guar gum, and 1 part of fatty alcohol polyoxyethylene ether. The prepared methyl silicone oil emulsion has a particle size of 31.47 μm, a shelf life of more than 12 months at room temperature, and more than 30 days at 50° C.

Embodiment 2

[0028] Add 60 parts of dimethicone oil with a viscosity of 300000cs to the high-efficiency shearing emulsification equipment, add 4 parts of betaine, then add 10 parts of water, stir evenly, add 25 parts of dilution water, after stirring evenly, add 1 guar gum. The prepared methyl silicone oil emulsion has a particle size of 34.18 μm, a shelf life of more than 12 months at room temperature, and more than 30 days at 50° C.

[0029] The test methods and test standards of various properties in this example are the same as those in Example 1.

Embodiment 3

[0031] Add 60 parts of dimethicone with a viscosity of 500000cs to the high-efficiency shearing emulsification equipment, add 4 parts of betaine, add 1 part of guar gum, then add 10 parts of water, stir evenly, and add 25 parts of dilution water , after stirring evenly, add 1 part of fatty alcohol polyoxyethylene ether. The prepared methyl silicone oil emulsion has a particle size of 38.56 μm, a shelf life of more than 12 months at room temperature, and more than 30 days at 50° C.

[0032] The test methods and test standards of various properties in this example are the same as those in Example 1.

Abstract

The invention discloses a preparation method of large-particle-size high-viscosity methyl silicon oil emulsion. The high-viscosity methyl silicon oil emulsion is prepared by adopting advanced efficient-shear emulsion equipment. The large-particle-size methyl silicon oil emulsion with the particle size D50 of more than 20mum is prepared by selecting high-viscosity methyl silicon oil as well as a surfactant and water that are added for adjustment. The large-particle-size high-viscosity methyl silicon oil emulsion prepared by the invention is simple and efficient in preparation process and easy in process operation, and has a prominent application effect in personal care products; especially, the large-particle-size high-viscosity methyl silicon oil emulsion can be compounded with small-particle-size silicon oil emulsion in hair care products, so that hair has excellent dry-wet combing performance and smooth and soft handfeel.

Description

technical field [0001] The invention relates to a preparation process of a super-large particle size high-viscosity methyl silicone oil emulsion, in particular to a preparation process of a super-large particle size high-viscosity methyl silicone oil emulsion suitable for use in the personal care industry. Background technique [0002] Dimethicone has a wide range of applications in personal care products due to its excellent smoothness, water repellency, breathability, UV resistance and silky touch. , good film-forming properties, can be used to repair hair damage and improve combability, has a unique lubricating function, and has excellent application performance as a skin moisturizer and hair conditioner. But on the other hand, because of its hydrophobicity, silicone oil is difficult to disperse in the water phase, and if it is directly applied to hair fiber, the hand feel, fastness and elasticity are not ideal. Therefore, it needs to be prepared into a silicone oil emuls...
