PURPOSE:To obtain an organosilicon resin useful for cosmetics, in an industrially advantageous way without using an aromatic hydrocarbon solvent such as toluene by carrying out hydrolysis and condensation reaction in a cyclic organopolysiloxane solvent of a specific formula. CONSTITUTION:This resin is obtained by hydrolysis and condensation reaction of at least one kind of organosilicon compound selected from the compounds of (B) the formula R<2>3SiOSiR<2>3 (R<2> is the same as R<1>) and (C) the formula R<2>3SiOH with (D) a silane of the formula (R<3>O)4Si (R<3> is the same as R<1>) and/or a partially hydrolyzed condensate thereof in a cyclic organopolysiloxane solvent (A), of the formula [R<1> is a (substituted) monovalent hydrocarbon; (n)>=4]. It is preferable that the hydrolysis and condensation reaction be conducted in either a solventless state or in a 1-10C aliphatic alcohol solvent followed by addition of the component A to conduct a solvent substitution.

However, since the aromatic hydrocarbon solvent may remain in the silicone resin produced as described above, it is a serious problem when it is used for cosmetics. Therefore, in the production of a silicone resin for cosmetics, it is necessary to carefully remove the solvent or replace it with another cosmetics solvent, and a solvent removal step or a solvent replacement step is required for a long time. From such a thing,
There is a need for silicone resins made without the use of aromatic hydrocarbons.

In the second method, hydrolysis and condensation can be carried out in the same manner as described above, and solvent substitution can be carried out by a conventional method. For example, a raw material for hydrolysis is charged into a reactor, acids are added, water is added dropwise with stirring, and solvent-free or methanol, ethanol, etc. having 1 to 10 carbon atoms.
Hydrolysis and condensation are carried out in an aliphatic alcohol solvent of 10 to neutralize the acids after hydrolysis, and then the cyclic organopolysiloxane of formula (1) is preferably 1 to 80%, more preferably 10 to 50%. Added in the amount of 50-150

Therefore, according to the above-mentioned method for producing an organosilicon resin, since a silicone resin can be obtained without using an aromatic hydrocarbon solvent such as toluene or xylene, the aromatic hydrocarbon solvent may remain. Thus, it is possible to omit the step of replacing the solvent, which has been conventionally performed in the production of an organosilicon resin, and it is possible to reliably produce a silicone resin which is useful as a raw material for cosmetics. Furthermore,
The molecular weight distribution and shape of the silicone resin can be adjusted by changing the blending amount of the hydrolysis raw material, the type of acid catalyst, the addition amount, the reaction temperature, the reaction time, the addition amount of the solvent, and the addition method. A silicone resin can be manufactured according to the application.
