Abstract
The invention provides a preparation method of a liquid propyl silicone resin blend for personal care. The propyl silicone resin provided by the invention is prepared by the following method: the preparation method comprises the steps of taking n-propyl trimethoxy silane as a raw material, and carrying out hydrolytic polymerization reaction in the presence of water, an organic solvent and an acidic catalyst. The propyl silicone resin developed and produced by the invention has the excellent characteristics of high viscosity, good thermal stability, water resistance, moisture resistance and the like, and is environment-friendly and nontoxic. Even after stretching and washing, the films formed from this resin remain smooth and intact. The propyl groups on the silane chains can be freely bent and rotated, and the D5 or flexible alkane is blended, so that good lubricity, elasticity and stretchability can be provided for the product. In addition, the process route can reduce the generation and emission of strong corrosion and toxic substances in the production process, reduce the production cost by recycling the recovered solvent, and avoid the pollution to the environment.
Description
Technical Field
The invention belongs to the field of preparation of cosmetic intermediates, and particularly relates to a preparation method of a liquid propyl silicone resin blend for personal care.
Background
Under the condition that the scientific technology of China is continuously developed, the variety and the quantity of the raw materials of cosmetics are continuously increased, and how to ensure the safety of the components of the cosmetics and the environment protection in the production process are already important and difficult to study. The toxicological properties of cosmetic ingredients can affect the ingredient safety to a great extent, and thus the cosmetic use safety. The structure and the shape of the components of the cosmetic are similar to those of cells in human bodies, so that the appearance of the cosmetic is formed, and the quality of the components determines the quality and the efficacy of the cosmetic. The silicone resin is used as a novel organosilicon additive, has good film forming property and wear resistance, has better skin texture and hand feeling when being used on skin, and is therefore popular with cosmetic manufacturers in the field of cosmetic application.
The silicone resin can accelerate the absorption of nutrients by skin, and can further repair skin components, so that the skin epidermis is quickly repaired, and the stretching capability of the skin epidermis is enhanced. Zhou Shuchun et al have found that phenyl propyl-containing silicone resins have better refractive properties than conventional phenyl silicone oils, can significantly improve the gloss of lipsticks, and can also improve the absorption of ultraviolet rays by the products.
The existing silicone resins for personal care have the defects of poor adhesion, poor film forming property, poor smoothness and stretchability (poor hand feeling) and the like, so that the wider commercial application of the silicone resins is limited, and a silicone resin with more excellent performance is needed to improve the defects, so that the personal care products have better use value and feel.
In the prior art, chlorosilane is mainly used as a raw material, and silicon resin is prepared by hydrolytic polymerization. Hao Wei vinyl silicone resin is prepared by hydrolysis polymerization of vinyl trichlorosilane serving as a raw material in an ethanol and xylene system. Song Xinfeng phenyl propyl silicone resin is obtained by hydrolysis and polycondensation reaction of phenyl trichlorosilane and propyl trichlorosilane serving as raw materials in toluene and a water system. However, the preparation of silicone resins from chlorosilanes generates a large amount of hydrochloric acid (HCl), which corrodes production equipment and is harmful to the environment, and the generated wastewater needs special treatment, which further increases the process production cost.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a novel silicon resin-propyl silicon resin and a preparation method thereof.
The propyl silicone resin provided by the invention is prepared by the following method: n-propyl trimethoxy silane is used as a raw material, and hydrolysis polymerization reaction is carried out in the presence of water, an organic solvent and an acid catalyst to obtain propyl silicone resin.
Wherein, the acid catalyst can be trifluoromethyl sulfonic acid or concentrated sulfuric acid with the mass concentration of 98 percent;
the organic solvent can be a mixture of two or more of ethanol, cyclohexane and toluene;
the molar ratio of the n-propyl trimethoxy silane to the water to the acid catalyst can be as follows: 4:11-12:0.056-0.08, specifically 4:11.66:0.056, 4:11.66:0.064 or 4:11.66:0.08;
the hydrolysis polymerization reaction is operated as follows: under the condition of room temperature, adding water and an organic solvent into a three-port reactor with a thermometer, starting mechanical stirring, and stirring until the water and the organic solvent are uniformly mixed; adding n-propyl trimethoxy silane, continuously stirring, dropwise adding trifluoromethyl sulfonic acid or concentrated sulfuric acid with the mass concentration of 98%, stirring, starting circulating water, heating to 50 ℃, and reacting for 50min under the condition; continuously heating to 85 ℃, continuously reacting for 6 hours after the solvent is distilled out, washing with a large amount of deionized water after the reaction is finished, separating liquid, and obtaining the propyl silicone resin after short-path distillation. The synthetic process route diagram is shown in figure 1.
The obtained propyl silicone resin is clear and transparent viscous liquid, the viscosity of the propyl silicone resin is 20000 to 30000mPas (25 ℃), and the refractive index of the propyl silicone resin is 1.4400 to 1.4500 (25 ℃).
The invention also provides a liquid propyl silicone resin blend product.
The liquid propyl silicone resin blend product comprises propyl silicone resin and a blend solvent;
the blending solvent is any one of decamethyl cyclopentasiloxane (D5) and isododecane;
the mass ratio of the propyl silicone resin to the blend solvent can be: 1:1/3-1, and can be specifically 1:1 or 1:1/3.
The liquid propyl silicone resin blend product is prepared by bubble-free blending of propyl silicone resin and a blend solvent. The preparation process route diagram is shown in fig. 2.
The liquid propyl silicone resin blend product is clear and transparent liquid, the viscosity of the liquid propyl silicone resin blend product is 100-300 mPas (25 ℃), and the refractive index of the liquid propyl silicone resin blend product is 1.4100-1.4400 (25 ℃).
The use of the propyl silicone resin, liquid propyl silicone resin blend products described above in personal care products is also within the scope of the present invention.
In such applications, the personal care product may be: make-up, liquid foundations, lotions, sunscreens, lipsticks, hair care agents.
In the personal care products, propyl silicone resin, liquid propyl silicone resin blend products are used to improve the slip, abrasion, mar and gloss properties of personal care products.
The present invention also provides a personal care product comprising the propyl silicone resin or liquid propyl silicone resin blend product described above.
The invention adopts a brand new process route, takes n-propyl trimethoxy silane as a raw material, and prepares the propyl silicone resin through hydrolytic polymerization reaction in a system of an organic solvent, water and an acid catalyst. The developed propyl silicone resin has the excellent characteristics of high viscosity, good thermal stability, water resistance, moisture resistance and the like, and is environment-friendly and nontoxic (slightly toxic). The silicone resin has better film forming property, and the formed film can be flexibly transferred and is resistant to flushing, and even if the film is stretched and washed, the film formed by the resin still remains smooth and intact. The propyl groups on the silane chains can be freely bent and rotated, and the D5 or flexible alkane is blended, so that good lubricity, elasticity and stretchability can be provided for the product. In addition, the process route can reduce the generation and emission of strong corrosion and toxic substances in the production process, reduce the production cost by recycling the recovered solvent, and avoid the pollution to the environment.
