Moisturizing cream and preparation method thereof

Abstract

The invention provides moisturizing cream and a preparation method thereof. The moisturizing cream comprises: by mass, 5-40%, preferably 10-25%, more preferably 15-35%, of a grease; 2.1-20%, preferably 2.5-10%, more preferably 3-8%, of an emulsifier; 1-40%, preferably 5-30%, more preferably 10-25%, of a humectant; 0-2%, preferably 0.1-2%, more preferably 0.1-1%, of a thickener; 1-10%, preferably 2-10%, more preferably 5-10%, of a skin conditioner. The emulsifier is a composite emulsifier composed of polyglyceryl-6 stearate, jojoba esters, polyglyceryl-3 beeswax, and cetyl alcohol. The moisturizing cream can form a constantly moisturizing protective film with better moisturizing degree on the skin surface, which is a bionic skin sebum film.

Description

technical field [0001] The invention relates to a moisturizing cream and a preparation method thereof, belonging to the field of cosmetics. Background technique [0002] Due to various factors, such as: skin aging caused by aging, stress from the external environment, severe temperature difference between the external and internal environment, frequent skin washing due to environmental pollution, and thermal aging of the skin caused by direct sunlight, etc. It becomes dry, causing the stratum corneum of the skin to peel off. As a result, the skin looks rough, brittle, dry and dull. [0003] At present, it is one-sidedly believed that dry skin is due to the lack of lipids on the skin surface. In fact, just applying oil to the surface of the skin does not make the skin soft. The real cause of the skin is the lack of moisture in the stratum corneum. The stratum corneum controls the moisture of the outer skin and acts as a barrier. In order to maintain the moisture balance of...

AI Technical Summary

Problems solved by technology

[0004] Traditional cosmetics mainly divide the raw materials with moisturizing function into two categories. One type of humectant, such as glycerin, propylene glycol, etc., moisturizes through water absorption, but it does not fully consider the moisture-locking and moisturizing of the skin and long-lasting nourishment.

Another type of non-polar moisturizer, such as vaseline and white mineral oil, etc., they form a closed oil film on the surface to reduce the evaporation of water on the skin surface, and the water in the lower layer of the tissue diffuses to the stratum corneum, so that the stratum corneum can be further hydrated to reach Moisturizing effect; however, this kind of moisturizer will make the skin have poor air permeability and be too greasy, resulting in poor use feeling, increasing the skin burden for oily skin consumers, resulting in clogged pores and the risk of acne and acne skin

[0005] In addition, in the prior art, there are also some moisturizing cosmetics that add a lot of functional moisturizing components, without sufficient consideration to promote percutaneous absorption, so that many functional moisturizing components stay on the skin surface and do not enter the stratum corneum of the skin. It cannot effectively stimulate the deep moisturizing ability of the skin, and the skin cannot be moisturized for a long time, resulting in a waste of the cost of cosmetic functional components
