Abstract
The invention discloses a camellia seed oil extract moisturizing cream which comprises an emulsifier, glycerol, butanediol, a preservative, a modified tea seed oil deodorized distillate, a bile acid mixed micelle, a surfactant, organosilicon modified polyurethane, a bile acid crude product and tea seed oil crude oil. According to the invention, the tea seed oil deodorized distillate is extracted by refining the crude tea seed oil, so that the moisturizing effect of the face cream is improved. The deodorized distillate is modified to enhance the effect of phytosterol on skin in cream, prevent skin dryness and sclerosis, and soften keratinized skin. The bile acid ionic micelle can promote the absorption of skin on fatty acid, and reduce the effects of cream and water. The organosilicon modified polyurethane is added to reduce the moisture in the cream and enhance the cohesiveness and permeability of the cream. The camellia seed oil extract moisturizing and moisture-preserving cream disclosed by the invention realizes the maximum effect of moisturizing and moisture-preserving on skin.
Description
Technical Field
The invention relates to the technical field of cosmetics, in particular to camellia seed oil extract moisturizing and hydrating cream.
Background
Water is a source of life, generally, 70-90% of life quality is water, normal metabolic activity can be carried out by a human body only when the water content of cells is not less than 65%, and the in vivo metabolism can reach a state that the cells are active when the water content is more than 70%. The water content and the water existence state influence the metabolism and the life activity. Skin is a part of the body, and dry, tight, rough and dark skin can appear when the skin lacks moisture; when the moisture content of the skin is extremely low, the skin barrier is easily damaged, and external factors such as ultraviolet rays, dust, microorganisms and the like are easy to attack the skin, so that skin problems such as aging, sensitivity and the like are caused, so that sufficient moisture can ensure that the skin functions normally, the skin metabolism is promoted to be activated, and the skin is also a basic condition for maintaining the skin state and delaying aging.
Moisturizing is the maintenance of skin moisture and water. If only water is supplemented, water is not locked, and water is prevented from losing, just like a container with a leak, the addition of more water is also a vain; if only water is supplemented and locked, the water is not prevented from being dissipated, and the water still dissipates quickly like a rainy asphalt road; if only water supplement and water loss prevention are considered, and water locking is neglected, the skin is still in a dangerous state of water shortage due to overhigh local temperature and blocked water absorption. Therefore, the water replenishing, the water locking and the water loss prevention are all impossible. Adding water after water replenishing. The lotion, spray, essence, jelly mask and the like can increase the water content and humidity around skin cells due to the emulsion and the cream in the aspect of water content. Water retention, i.e., retention, increases water content, which is generally increased by both methods of promoting water retention and enhancing water absorption of the skin. The promotion of the skin water-fixing ability is generally achieved by filling with cell lipids, mucopolysaccharides, and the like. The water absorption capacity of the skin can be enhanced by utilizing the moisture absorption of the raw materials, and the water content of the skin is improved by capturing water molecules in the air. To prevent moisture loss, skin tightness is improved. When a film with good sealing performance is formed in terms of moisture retention, moisture can be retained in cells or intercellular spaces, and the emollient and the sealant can be prevented from water dispersion and evaporation to the maximum extent.
In life, a lot of people neglect the effects of lotion and cream when protecting skin, and only use the toner, so that the moisture is allowed to evaporate in real time, and the moisture is not beneficial to keeping. Therefore, it is necessary to design the camellia seed oil extract moisturizing and moisturizing cream which can lock water and prevent water loss.
Disclosure of Invention
The invention aims to provide a camellia oil extract moisturizing and hydrating cream to solve the problems in the background technology.
In order to solve the technical problems, the first aspect of the invention provides the camellia oil extract moisturizing and hydrating cream which comprises the following raw materials in parts by weight:
20-25 parts of an emulsifier, 10-15 parts of glycerol, 10-15 parts of butanediol, 2-4 parts of a preservative, 10-15 parts of a modified tea seed oil deodorized distillate, 5-10 parts of a bile acid mixed micelle, 5-10 parts of organosilicon modified polyurethane, 50-100 parts of a bile acid crude product and 100-200 parts of a tea seed oil crude oil.
Preferably, the modified tea-seed oil deodorized distillate is prepared by modifying a byproduct obtained from refined oil of crude tea-seed oil.
Preferably, the bile acid mixed micelle is obtained by reacting bile acid with a tea seed oil deodorization distillate.
Preferably, when the organosilicon modified polyurethane is synthetic polyurethane, organosilicon containing amino is introduced into a polyurethane chain segment in the process of synthesizing a prepolymer.
Preferably, the preservative is one of an alcohol preservative, a formaldehyde donor and aldehyde derivative preservative, and other organic compound preservatives.
In the technical scheme, the tea seed oil deodorization distillate can reduce the loss and evaporation of moisture to the greatest extent, the skin moisture-shrinking and preserving capacity is directly improved, and the modified tea seed oil deodorization distillate obtained by treating the tea seed oil deodorization distillate is better in effect.
In the technical scheme, the bile acid ionic micelle can promote the absorption of skin on fatty acid, can protect the face cream as much as possible and reduce the combination with water, so that the added organosilicon modified polyurethane can be combined with more water.
In the technical scheme, the added organosilicon modified polyurethane increases the cohesiveness and permeability of the cream.
The second aspect of the invention provides a preparation method of camellia seed oil extract moisturizing and moisture-preserving cream, which comprises the following steps:
(1) refining the tea seed oil to prepare tea seed oil deodorized distillate;
(2) preparing modified tea seed oil deodorized distillate;
(3) extracting bile acid;
(4) preparing bile acid ionic micelle;
(5) preparing organic silicon modified polyurethane;
(6) mixing glycerol and butanediol and stirring;
(7) uniformly mixing and stirring the substance mixture obtained in the step (6) and the step (2);
(8) adding the substance obtained in the step (7) into an emulsifier, and mixing and stirring;
(9) mixing the substance obtained in the step (8) with the substance obtained in the step (4), and uniformly stirring;
