Problems solved by technology

However, different oil phase thickeners have different thickening effects on different oils and have strong selectivity, and the requirements for raw materials in the field of personal care are more stringent; at the same time, waxes are hard to the touch, so they are added to personal care products will reduce the slippery feeling

Abstract

The invention provides a core-shell structure soft bead stable at low temperature. Specifically, hydrogel formed by a glue solution composition of an aqueous gel substance, a thickening agent, sodium alginate, a humectant and water is used as a shell layer, wax, grease, an oily thickening agent and a photosensitive material are used as core materials of the soft bead with the core-shell structure, and the soft bead is prepared by dropping pills. The soft beads cannot be broken at the low temperature of-15 DEG C, the permeability of the personal care product cannot be changed after the temperature is recovered to the room temperature, and the protection effect on active substances cannot be reduced.

Description

technical field [0001] The invention belongs to the field of personal care, and in particular relates to a preparation method of low temperature stable core-shell structure soft beads and a preparation method thereof. Background technique [0002] In recent years, in order to achieve the purpose of anti-oxidation, anti-aging, and reducing wrinkles, more and more active substances have been added to personal care products, but most of these active substances are sensitive to the external environment, and their use conditions in cosmetics are relatively strict. Harshness, air, light and inappropriate pH may make it deteriorate and reduce its efficacy; therefore, how to protect active substances from deterioration in cosmetics has become a hot research topic in the field of skin care in recent years. In the past, active substances were usually added to skin care products. Some antioxidants, UV shielding agents or actives are modified to reduce their exposure to the external env...
