Description

Mild nipple cream and preparation method thereof

Technical Field

The invention belongs to the field of skin care products, relates to a skin care product, and particularly relates to mild nipple cream and a preparation method thereof.

Background

The nipple cream is a breast care product for mothers, and has the functions of moistening skin, and effectively preventing nipple rupture and other skin dryness. The nipple ointment has the action principle of moisturizing therapy, keeps moist and promotes wound healing, certain humidity is required for cell growth in the wound healing process, the wound healing speed is improved by 50% in a moist environment, and moisturizing nursing of the wound provides an optimal environment for wound healing. However, the currently marketed products have the following disadvantages:

(1) most of the products sold in the market at present are cream-shaped or full-fat, and are sticky when in use;

(2) at present, products sold in the market are basically packaged in extrusion bottles, and the products are extruded firstly and then smeared by hands when used, so that the products are inconvenient to use, and the hands are easy to pollute if not cleaned;

(3) most products only have the functions of supplementing water and repairing, but infants bite nipples forcibly, and the epidermis is soaked by saliva for a long time to become soft, stripped and eroded, so that allergy is easily caused;

(4) because newborns are sensitive to essence, the products are not added with essence basically, and the selected raw materials such as mutton tallow are heavy in taste.
