Problems solved by technology

Mineral oil, also known as paraffin oil and white oil, is a mixture of liquid hydrocarbons obtained by crude oil atmospheric pressure and vacuum fractionation, solvent extraction and dewaxing, and hydrofining, mainly saturated naphthenes and paraffins, naphthenes The molecular weight of paraffins is low and volatile, so mineral oil has a certain volatility, that is, the oil film formed by mineral oil on the skin is difficult to maintain for a long time, the moisturizing time is not long, and the moisturizing effect is not ideal

Abstract

The invention provides a liquid natural rubber-based skin moisturizer and a preparation method thereof. The invention firstly prepares a urea-montmorillonite compound, then prepares a gelatin-lignin compound, and then urea-montmorillonite compound is prepared by an extrusion method. Composite and gelatin-lignin compound are prepared into gelatin-lignin-urea-montmorillonite organic-inorganic colloidal compound, gelatin-lignin-urea-montmorillonite organic-inorganic colloidal compound is stirred into liquid natural rubber It is a colloidal liquid, which is a skin moisturizer based on liquid natural rubber. This moisturizer can not only form a uniform oil film on the skin surface that inhibits water evaporation, but also absorb moisture from the environment to moisturize the skin, with excellent moisturizing performance .

Description

Technical field: [0001] The invention provides a liquid natural rubber-based skin moisturizing agent and a preparation method of the skin moisturizing agent, belonging to the field of daily cosmetics. Background technique: [0002] Maintaining the dynamic water balance of the skin is an important factor to ensure skin health. However, this balance will be destroyed by various internal and external factors, resulting in symptoms such as dry skin, dull skin, and easy allergies. The dynamic water balance of the skin is maintained through the sealing of the stratum corneum barrier and the combination and storage of water molecules by hyaluronic acid in the dermis. There are two approaches to achieving the skin's dynamic water balance. One way is that when the relative humidity of the surrounding environment is greater than that of the skin surface, you can smear a substance that is easy to absorb water on the skin so that it can absorb moisture from the environment to maintain ...
