-
, (2021/11/26)
The subject of the present disclosure is a composition for coloring keratinous material, in particular human hair, containing in a cosmetic carrier (a) at least one organic silicon compound selected from silanes having one, two or three silicon atoms, said organic silicon compound further comprising one or more basic chemical functions and one or more hydroxyl groups or hydrolysable groups per molecule,(b) at least one colorant compound from the group of pigments and/or direct dyes, and(c) at least one film-forming hydrophilic polymer.
High-purity bis[(3-trialkoxysilyl)-propyl]amine synthesis process
-
Paragraph 0030-0031, (2020/03/13)
The invention discloses a high-purity bis[(3-trialkoxysilyl)-propyl]amine synthesis process, which comprises: 1, by using chloropropyltrialkoxysilane and aminopropyltrialkoxysilane as raw materials, dropwisely adding the chloropropyltrialkoxysilane into the aminopropyltrialkoxysilane in an inert gas atmosphere, and keeping the temperature after dropwisely adding; 2, adding a dechlorinating agent into the system, stirring, and carrying out a dechlorination reaction; 3, after the dechlorination reaction is finished, cooling, and separating the precipitated salt out of the system to obtain a reaction solution; 4, introducing ammonia gas into the reaction solution, stirring, and filtering out an insoluble salt after the reaction is finished so as to obtain a reaction solution containing bis[(3-trialkoxysilyl)-propyl]amine; 5, carrying out reduced pressure distillation on the reaction solution containing the bis[(3-trialkoxysilyl)-propyl]amine to prepare the bis[(3-trialkoxysilyl)-propyl]amine finished product. According to the invention, with the method, the product yield is greatly improved, and the product purity is also greatly improved.
PROCESS FOR DYEING HAIR
-
, (2021/01/22)
The subject of the present disclosure is a process for dyeing human hair, in which a pretreatment agent (A) which contains at least one organic silicon compound of the formula (I) and/or (II) and contains no direct dyes and no pigments, anda colorant (B) which contains at least one organic silicon compound of the formula (I) and/or (II) and further contains at least one colorant compound from the group of direct dyes and/or pigments, can be applied to the hair, wherein the organic silicon compounds of formulae (I) and (II) are defined as follows [in-line-formulae]R1R2N-L-Si(OR3)a(R4)b??(I),[/in-line-formulae] [in-line-formulae](R5O)c(R6)dSi-(A)e-[NR7-(A′)]f—[O-(A″)]g-[NR8-(A′″)]h—Si(R6′)d′(OR5′)c′??(II).[/in-line-formulae]
Process for manufacturing polysiloxane microcapsules that are functionalized and are not very porous
-
Page/Page column 4, (2016/09/26)
A method is provided for encapsulating products that can have lipophilic or hydrophilic, including volatile, properties in a polysiloxane membrane that is particularly impervious. A method is also provided for evaluating the imperviousness of capsules. The present method includes the following steps: a) formation of droplets by an emulsion between an oily phase containing the product to be encapsulated and an acidic aqueous phase heated to around 50° C. and in the presence of surfactants; b) addition and hydrolysis of at least one silane in order to obtain a silanol; c) increasing the pH in order to start condensation of the silanol to form a first membrane around the droplets of the product to be encapsulated; d) lowering the pH; e) increasing the pH, optionally preceded by adding a silane, in order to obtain a new condensation of silanol around the droplets of the product to be encapsulated.
ORGANOSILICON COMPOUND AND ITS PRODUCTION METHOD, COMPOUNDING AGENT FOR RUBBER, RUBBER COMPOSITION, AND TIRE
-
, (2012/12/13)
A method for producing a sulfur-containing organosilicon compound capable of dramatically reducing hysteresis loss of the cured rubber composition and improving abrasion resistance and its production method are provided. A compounding agent for rubber containing the sulfur-containing organosilicon compound, a rubber composition prepared by blending such compounding agent for rubber, and a tire produced by using the cured rubber composition are also provided. The sulfur-containing organosilicon compound has a hydrolyzable silyl group, amino group, and mercapto group.
Process for the preparation of N-substituted aminoalkylsilanes
-
, (2008/06/13)
N-substituted aminoalkylsilanes are obtained via a selective process which comprises reacting a cyanoalkylsilane with a primary or secondary amine in the presence of a heterogeneous hydrogenation catalyst selected from the group consisting of rhodium, platinum and palladium.
