TABLE 1 oil absorption for each of the examples and comparative examples
As can be seen from Table 1, compared with the commercially available skin care product of comparative example 1, the skin care oil absorption ball has an oil absorption rate of less than 10%, the skin care oil absorption ball of the invention has an oil absorption rate of 12.3-14.9%, and a good oil control effect, and the attapulgite powder material mainly utilizes a good length-diameter ratio and rich pores to realize the oil absorption. Comparing comparative example 2 with examples 1-4, although the oil absorption rate of comparative example 2 is higher, the attapulgite powder of comparative example 2 is seriously fallen off in use, because the comparative example 2 does not contain the surfactant, the use strength of the attapulgite blank cannot be strengthened, and the attapulgite powder particles are fallen off in use. Comparative example 3 the attapulgite powder has a low oil absorption rate because the content of the surface modifier in the comparative example 3 is 10 parts, which is higher than 1-5 parts defined in the invention, and because the content of the surface modifier is high, the strength of the attapulgite blank can be improved, but the excessive surface modifier can cause the surface adsorption pore diameter of the skin-care oil absorption ball to be blocked, and the oil absorption rate is too low. Compared with the comparative example 4 and the examples 1-4, although the oil absorption rate of the comparative example 4 is up to 22%, the attapulgite powder falls off in the using process, the sintering temperature of the comparative example 4 is 600 ℃, which is lower than 700-1000 ℃ defined by the invention, the lower sintering temperature causes insufficient crystal transformation of the skin care balls, the element mobility is low, and the surface structure of the skin care balls cannot be fused, so that the surface powder falls off. Compared with the comparative example 5 and the examples 1-4, the skin care ball has high strength and no powder falling, but the oil absorption rate of the comparative example 5 is only 5%, and the integral structure of the skin care ball collapses and the surface pore structure is damaged at 1050 ℃, so that the adsorption capacity is lost and the oil absorption rate is low.
