The fluidity starch is prepared by introducing octenyl hydrophobic groups on the surface of starch granules, and then crosslinking with aluminum ions to shield hydroxyl groups on starch molecules to the maximum extent, so that the hydrophilicity of the starch is quickly weakened, the intermolecular forces such as hydrogen bonds and Van der Waals among the starch granules are greatly reduced, and the fluidity of the starch is good macroscopically. Meanwhile, due to the existence of octenyl, starch molecules also have certain hydrophobicity. The talcum powder obtained by the method has better activation index, greatly improved hydrophobicity, smaller storage limit and difficult consolidation in a humid environment; smaller average particle size, easy dispersion, better smooth feeling and better skin feeling. The talcum powder obtained by the invention has the characteristics of stable effect, wide application range, greenness, no side effect and the like.

The following are exemplary: the method comprises the following specific implementation steps of selecting 1000 experimenters to perform trial feedback on the using effect of the existing talcum powder and the infant corn talcum powder, and setting an experimental group and a comparison group, wherein the experimental group is used for performing the somatosensory trial on the 1000 selected experimenters by using the infant corn talcum powder provided by the invention and acquiring the feedback information of the experimenters, the comparison group is used for performing the somatosensory trial on the 1000 selected experimenters by using the existing infant talcum powder and acquiring the feedback information of the experimenters, and the tested performance comprises the following steps: evaluating the moisture absorption, the skin whiteness, the dispersion and the skin feel of the experiencers, wherein all the item scores are 1-10, summing the scores of all the experiencers and taking the average value to obtain the following experimental results:

	moisture absorption property	White feeling of skin	Dispersibility	Skin feel
					Experimental group	8.1	7.9	7.7	8.0
Control group	5.3	4.5	4.1	4.4

The higher the hygroscopicity is, the stronger the sweat absorbing ability is, and the drying effect is better after the use; the lower the skin whiteness and the dispersibility, the obvious agglomeration phenomenon is shown when the skin-whitening cream is smeared, the skin-whitening cream is not easy to be smeared evenly, and a relatively white effect is shown; higher skin feel indicates better use experience for the experiencer. The experimental group and the control group showed large differences in hygroscopicity, skin whiteness, dispersion and skin feel. The control group had lower moisture absorption, skin whiteness, dispersion and skin feel scores. Because the common talcum powder has the hydrophilicity and is not easy to disperse, the common talcum powder is easy to agglomerate when being smeared, generates stronger white feeling and reduces the feeling experience value of people. The experimental components have good dispersibility and higher skin feel scoring result. The data show that the infant corn talcum powder prepared by the method has better using effect.
