Something about the cosmetics materials that you may interested

Cosmetics are compounded mixtures of various raw materials that have been rationally formulated. Cosmetics come in a wide variety of raw materials and properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two major categories: matrix materials and auxiliary materials. The former is a kind of main raw material of cosmetics, and it occupies a large proportion in the cosmetic formula, and is a substance that plays a main function in cosmetics. The latter acts on the formation, stabilization or imparting of colour, aroma and other properties of the cosmetic, which are not very useful in cosmetic formulations but are extremely important. Cosmetics are chemical mixtures that are processed by natural, synthetic or extracted various substances as raw materials and processed by heating, stirring and emulsification.

Introduction

The main raw materials for cosmetics are usually divided into general matrix materials and natural additives. Cosmetics universal matrix materials include: oily raw materials, which are the most widely used raw materials for cosmetics.

It acts as a protective, moisturizing and softening skin in skin care products, and plays a role in shaping and hairdressing in hair products. Surfactant can reduce the surface tension of water, and has decontamination, wetting, dispersing, foaming, emulsifying, Thickening and other functions, known as industrial MSG; moisturizer, is an essential raw material for cream cosmetics, its role is to prevent the cream from cracking and keep the skin moisture; adhesive, mainly used in hair gel, mousse and glue Mask, powder, mainly used in the manufacture of fragrant powder products; pigments, dyes, mainly used in the manufacture of cosmetic modified products; preservatives, antioxidants, inhibiting microbial growth during the shelf life of cosmetics and during consumer use; Increase the fragrance of cosmetics and increase the value of the products; other raw materials, including UV absorbers, dye intermediates for dyeing black hair, perm raw materials, antiperspirants, deodorants, raw materials for preventing skin cracking, anti-acne raw materials, etc. Common natural additives include hydrolyzed gelatin, hyaluronic acid, superoxide dismutase (SOD), royal jelly, silk fibroin, leeches, pearls, aloe vera, medical stone, organic alfalfa, pollen, alginic acid, seabuckthorn, and Chinese herbal medicine.

Oily raw material

Oily raw materials include natural oily raw materials and synthetic oily raw materials. They mainly refer to oils and fats, wax raw materials, hydrocarbons, fatty acids, fatty alcohols and esters, etc., and are a major raw material for cosmetics. Grease is a general term for oils and fats, including vegetable oils and animal fats. The main component of fats and oils is fatty acid glycerides composed of fatty acids and glycerol.

Vegetable fat

There are three types of vegetable oils, dry oil, semi-dry oil and non-dry oil. Dry oils such as: linseed oil, sunflower oil; semi-dry oil such as cottonseed oil, soybean oil, sesame oil; non-drying oil refers to olive oil, coconut oil, castor oil and so on. Most of the oils used in cosmetics are semi-drying oils, and dry oils are hardly used in cosmetic raw materials. Commonly used oils are: olive oil, coconut oil, castor oil, cottonseed oil, soybean oil, sesame oil, almond oil, peanut oil, corn oil, rice bran oil, tea seed oil, sea buckthorn oil, avocado oil, stone chestnut oil, European nuts Oil, walnut oil, cocoa butter, etc.

Animal fat

Animal fats and oils are used in cosmetics such as leeches, egg butter, lanolin, lecithin, etc. Animal fats and oils generally include highly unsaturated fatty acids and fatty acids, which are inferior in color and odor compared with vegetable oils. Pay attention to the anti-corrosion problem when using it. The leeches oil has good affinity, is easily absorbed by the skin, is smooth and not greasy after use, and has excellent performance, so it is widely used in cosmetics, such as nutrient cream, moisturizer, hair oil, shampoo, lipstick and Sunscreen cosmetics, etc. Egg butter contains oils, phospholipids, lecithin and vitamins A, D, E, etc. It can be used as a raw material for lipstick cosmetics. Lanolin oil has good affinity, permeability and diffusibility to the skin, good lubrication and softness, easy to be absorbed by the skin, and no irritating to the skin; it mainly acts on anhydrous ointment, lotion, hair oil and bath oil. Lecithin is extracted from egg yolk, soybean and grain. It has the functions of emulsification, anti-oxidation and moisturizing the skin. It is a good natural emulsifier and is often used in moisturizer creams and oils.

Wax

Waxes are esters of high carbon fatty acids and high carbon fatty alcohols. The ester acts as a stabilizer in cosmetics, adjusts the viscosity, and reduces the greasy feel. The waxes mainly used in cosmetics are: palm wax, candelilla wax, jojoba wax, wood

Wax, lanolin, beeswax, etc.

The palm wax refined product is a white or light yellow brittle hard solid with a pleasant scent. The main components are beeswamel alkoxylate and wax wax. In cosmetics, the melting point of wax esters is mainly increased, hardness, toughness and gloss are increased, and there is also a tendency to lower viscosity, plasticity and crystallization. Mainly used in lipsticks, mascaras, hair removal wax and other products.

Candelilla wax is a pale yellow translucent or opaque solid. The delicate product has a lustrous and aromatic scent and is slightly viscous. The main components are carbohydrates, wax esters, higher fatty acids, higher alcohols, and the like. It is used in starch-like cosmetics such as lipstick.

Jojoba wax is a transparent, odorless, light yellow liquid. It is mainly a wax ester composed of a fatty acid of twelve or more carbons and a fatty alcohol. Its characteristics are not easy to oxidize and rancid, non-toxic, non-irritating, easy to be absorbed by the skin and have a good moisturizing effect. Therefore, it is widely used in moisturizers, creams, shampoos, hair conditioners, lipsticks, nail varnishes, baby care products and detergents.

Wood wax, also known as Japanese wax, is a pale milk wax with a sour taste, not hard, tough, malleable and sticky. Its main component is triglyceride of palmitic acid, which is vegetable fat or high-melting fat. It is easy to be compatible with beeswax, cocoa butter and other triglycerides, and is easily saponified by an alkali to form an emulsion. Used in lotions and creams.

Beeswax, also known as beeswax, has the characteristics of high melting point. Therefore, it has been a raw material for cold cream since ancient times, and it is also a raw material for making cosmetic cosmetics such as wax, rouge, lipstick, eye shadow stick and mascara. In addition, it has anti-bacterial, fungal, healing wound functions, and is also used in shampoos, shampoos, and high-efficiency anti-dandruff shampoos.

Lanolin is a cortical gland secretion from sheep. The product is a yellow translucent oily viscous ointment-like semi-solid. There are water and water. The main component is a fat of various fatty acids and fatty alcohols, belonging to a melting point wax. It has good emulsification, wetting and osmosis. It has soft skin, prevents defatting and prevents chapped skin. It can be compatible with a variety of raw materials and is a good cosmetic raw material. It is widely used in skin creams, sunscreen products and hair care esters. It is also used in cosmetics such as soaps and lipsticks.

Hydrocarbon

Hydrocarbon refers to a class of carbohydrates derived from the processing of natural minerals. They have a high boiling point, more than 300 ° C, no saponification price and acid value of animal and vegetable oils. According to its nature and structure, it can be divided into three major categories: aliphatic hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons. In cosmetics, it is mainly used as a solvent to prevent evaporation of moisture on the surface of the skin and improve the moisturizing effect of the cosmetic. Hydrocarbons commonly used in cosmetics are liquid paraffin, solid paraffin, microcrystalline paraffin, ozokerite, petrolatum and the like.

Liquid paraffin is also called white oil or wax oil. It is a colorless, transparent, odorless, odorless, viscous liquid. It is widely used in cosmetics such as hair oil, hair wax, hair cream, cream, cold cream and shaving cream.

Vaseline, also known as mineral grease, is a white and light yellow uniform paste. Primarily a mixture of C16-C32 higher alkanes and higher carbon olefins. It has the characteristics of odorless, odorless, chemically inert, good adhesion, low price, lipophilicity and high density. It is used in cosmetics such as skin creams, hair cosmetics, beauty cosmetics, such as: cleansing cream, beauty cream, hair wax, lipstick, eye shadow, mascara and hair cream. In the pharmaceutical industry, it is also used as an ointment base or as an important component of pharmaceutical cosmetics.

Since the paraffin wax has no adverse reaction to the skin, it is mainly used as a raw material for oils such as hair wax, balsam, blush cream and lipstick.

The ground wax is divided into two grades in cosmetics. The melting point of the first grade product is 74 ° C -78 ° C, mainly used as the raw material of the emulsion product; the melting point of the second grade product is 66 ° C -68 ° C, mainly used as an important raw material for wax and the like.

Squalane is produced by hydrogenation of squalene obtained from deep sea shark liver oil. It is a colorless, transparent, odorless, odorless, non-toxic oily liquid. The main components are myristic acid, myristate, squalene., squalane, etc. Squalane has good permeability, lubricity and safety and is often used in high-grade cosmetics such as creams, lotions, lotions, lipsticks, hair conditioners and eyeliners.
