The present invention discloses a formula of a cosmetic optical silicone massage head and a preparation process therefor. The formula of the cosmetic optical silicone massage head includes a component A and a component B; where the component A includes the following raw materials in parts by weight: 91.8% of polymethylsiloxane, 4.95% of hydroxy silicone oil, 2.75% of stearic acid, and 0.5% of platinum catalyst; and the component B includes the following raw materials in parts by weight: 91.8% of polymethylsiloxane, 4.2% of hydroxy silicone oil, 1.6% of hydrogen silicone oil, 2.3% of stearic acid, and 0.1% of ethynylcyclohexanol. The formula of the cosmetic optical silicone massage head according to the present invention has good fluidity, high transparency, high strength, high tensile strength, and good tear resistance.

Provided are a manufacturing method for a cellulose molded body, in which a low-crystalline cellulose molded body can be obtained by adjusting the molding conditions regardless of xylose concentration in constituent sugars of the cellulose material, and a cellulose molded body. Included are a cellulose dissolution step of dissolving a cellulose material in a cellulose-dissolving agent to obtain a cellulose solution; a molding step of discharging the cellulose solution into an aqueous molding solution at 10 to 70 C. comprising 20 to 50% of the cellulose-dissolving agent to produce a wet molded body; and a drying step of washing and then drying the wet molded body to obtain a cellulose molded body.

Methods for making a personal care product and a personal care product are provided. In one example, the method includes forming a first layer by an additive process. The first layer has a first composition that includes at least one filler component selected from the group of starch, bulking agent salt, granular acid, clay mineral, sorbitol, silica, titanium dioxide, and zinc oxide. A binder is applied to the first layer. A second layer is formed by the additive process overlying the binder. The second layer has a second composition that includes at least one filler component selected from the group of starch, bulking agent slat, granular acid, clay mineral, sorbitol, silica, titanium dioxide, and zinc oxide. At least one of the first composition and the second composition further includes at least one surfactant.

In an example, a method includes identifying, by processing circuitry, a feature of less than a threshold size of an object to be generated in additive manufacturing. In some examples the method further includes determining, by processing circuitry, a first density of a print agent to be applied to build material when generating the identified feature of the object based on an intended flexibility of the feature of the object. The method may further include determining, by processing circuitry, a second density of print agent to be applied to build material when generating another feature of the object.
