Release Date:2013-11-21 Source:admin Views:1185
Natural surfactants come from animals and plants , is more complex organic polymer . Due to its hydrophilicity , thereby to form an emulsion . And such materials have high viscosity and more beneficial to the stability of the emulsion . Such as lecithin, cholesterol, lanolin, tea saponin , proteins , saponins , sugars and alkyl glycosides . Such surfactants are generally smaller surface tension capacity , emulsifying capacity are not the same . But some have strong surface activity, such as tea saponin , alkyl glycosides , decontamination activity, and can be directly applied to the bath products, hair preparations. The majority of natural surfactant with excellent emulsifying properties , and has other features and functions in the pharmaceutical , food, cosmetics and detergent application of broad. Such surfactants most non-irritating , non-toxic side effects, high safety performance , readily biodegradable , better performance and compatibility . Is the future direction of surfactants , especially with broad application prospects in cosmetic products.
    1 , lecithin
    Lecithin is present in biological cells, such as animal eggs , brain and other tissues and plant seeds or germ , egg yolk phospholipids extracted from egg yolk ; soybeans are rich in lecithin. Lecithin emulsifying, dispersing a physiologically active antioxidant , is an excellent natural surfactants , emulsifiers important . It has multiple functions : ① can involved in the metabolism of cells, activation of cells, has anti-aging functions ; ② on cell infiltration and regulation, may soften and protect the skin ; ③ improve the wetting properties of oils and secondary development , more for regulation, hair care , skin cosmetics ; ④ have good film-forming properties can be improved detergent degreasing effect on the skin ; ⑤ prevention and treatment of eczema and various skin diseases ; ⑥ promote hair growth , there are hair healthy hair effect ; ⑦ with spice and pigment dispersion stabilizing role ; ⑧ role in maintaining the stability of the emulsion formulation . So lecithin can be widely different from the skin and hair care , bath and beauty cosmetics.
    2 cholesteryl
    Also known as cholesteric cholesterol. The presence of the animal brain and nerve tissue , and lanolin and yolk . Is a natural emulsifier. Characterized in its molecular structure , the hydrophobic effect of strong base , and thus suitable for oil-soluble emulsifier , i.e., W / O type emulsion . Skin sebum secretion rich in cholesteryl and derivatives thereof , the cholesteric role in skin and hair care . Which is also a co- emulsifier , with the promotion and enhancement of the function of other surfactants . Applied lipstick and eye makeup preparations, beneficial and stable pigment emulsion . Multi- use on oily skin care products.
3 , lanolin
Lanolin is sheep s sebaceous secretions , mostly extracted from wool . With strong emulsifying and osmosis . Easy for the hair and skin absorption , and its compatibility performance is also good. Lanolin derivatives have more emulsification. ① lanolin wax : It is an excellent water / oil emulsifier , for a variety of cosmetic ingredients have a good dispersion , used lipstick ; ② lanolin acid isopropyl fat : strong hydrophilic interaction , also has a water / oil emulsifying properties , can be used in a cream formulation ; ③ lanolin alcohol : a strong water / oil emulsion characteristics , but also to stabilize the oil / water emulsion ; ④ hydrogenated lanolin : it is both a water / oil emulsion , and oil / water emulsion stabilizers, absorbent, easy to be absorbed by the skin , commonly used in lipstick , etc. ; ⑤ lanolin acid soaps : potassium , sodium , triethanolamine , etc., with emulsification , the product of formula in the gas volume , the raw material can facilitate dispersion and stability. In short lanolin and its derivatives obtained by the emulsion stability , and easy to skin absorption , good emollient properties , so much for creams and oily emulsion.
    4 , tea saponin
    Tea is tea saponin extract structure is a triterpenoid saponins , strong surface activity, anti- hard water capacity and foaming capacity are high. Tea saponin has emulsification, detergency , wetting , dispersing , foaming and other features. Use its emulsifying properties , may develop different "oil phase" emulsifiers. Washing hair with tea saponin directly silk fabrics . To maintain the fabric of bright colors , and a protective fabric effect ; for shampoo with shampoo, conditioner , black hair and dandruff , hair loss prevention functions. Emulsifying ability than oleic acid soap , alkyl sulfonates and polyoxyethylene fatty alcohol ether emulsifier is an excellent natural surfactants . And more used in high-end shampoo and detergent preparations .
    5 , protein
    A protein consisting of amino acids , both hydrophilic group and hydrophobic group , which is essentially a polymer surfactant. Protein is necessary nutrients the body , mostly used as a food emulsifier, it resembles its kind , such as milk, egg protein , casein, soy protein , etc., all have a protective effect emulsification , foaming and colloids used in the food industry and more food emulsifier application . However, the application of different species of protein function and are not the same : ① mucin : is a glycoprotein , characterized in its molecular structure , able to bind water molecules , stable emulsions can be used as the secondary emulsifier in skin care products , nutritional and moisturizing effect , can also enhance the conditioning and stability of other active substances ; ② phosvitin ; extracted from the egg yolk , has significant capacity and stability of the surface properties of the emulsion , soluble in water. Good performance and compatibility with a variety of cosmetic ingredients , is also excellent nutritional agents, humectants , skin can increase the nutritional , skin care cosmetics are excellent emulsifying agents and nutrients ; ③ lipoproteins : the protein , cholesterol , phospholipids , and other emulsifier , which is a multifunctional and therefore emulsifiers and stabilizers. Lipoprotein also has some antibacterial activity , can be used for soap, shampoo , and a nutritional role . Commonly used in anti-wrinkle nutritional emulsion.
    6 , phytosterols
    Plant sterols can be soybean oil extraction. Of sitosterol, stigmasterol , campesterol , VE and other components. And cholesterol have similar physical and chemical properties . With a weak surface activity and bactericidal anti-inflammatory effect on hair care role , with its mixture of the shampoo with a silicone product quite . Can reduce static electricity, improve combing , hair care and UFA s role , should be particularly noted that the liquid crystal structure of plant sterols , and more are used to prepare liposomes. Stigmasterol is also a plant sterol , also with a surfactant , a co-emulsifier , also an antioxidant . Skin care cosmetics for skin clear water holding capacity , are excellent humectants , nutritional agents and conditioners. If used in conjunction with phospholipids , the effect will be better. Used for emulsion and hair care products.
    7 , alkyl glucosides
    Alkyl glucosides are made from natural renewable resource sugar synthesis. Because of its derived from natural substances that may be regarded as a natural surfactant. Skin irritation weak , with broad-spectrum antibacterial properties, and other types of surfactants have good compatibility performance. Wetting and foaming performance, and significant thickening effect, so it is widely applied in the field . Adding detergent, anti- hard water can increase detergency ; lotion for meals , can improve the solubility of the formulations and mild , reducing the skin degreasing ; used in hair care, skin care cosmetics, skin care moisturizer obvious , soft, moist and hair care, hair care functions.
    8 , saponins
    Many plants contain saponins , more than a detergency and emulsification capabilities are an important class of natural surfactant . ① Tenuigenin : a surfactant used as an emulsifier and dispersing agent for lotions , shampoo and stimulating hair growth has a dual function ; ② aescine : its salt with a surfactant , detergent and can be used as starting foaming agents , anti-inflammatory effects have antibacterial , with moisture absorption properties, excellent cosmetic conditioning agent , and a stable emulsion effect ; ③ Quillaja acid : is a saponin component , a surfactant having a good foaming power and strong . Can be widely used in shampoo cosmetic lotions, shampoo alternative decontamination in the ingredients that can give hair soft and shiny ; ④ camellia saponin : also has some surface activity, can be used as an emulsifier , there foaming , wetting and dispersing functions. For hair products , can soften the scalp, itching and anti- dandruff hair loss have functions used for hair cosmetics .
9 , sugars
   Saccharide natural surfactants , detergency weak, but more than a thickening and emulsifying capacity and emulsion stability. And a function of other aspects . ① carrageenan : the case of sugar. Is widely helped emulsifier has a stabilizing effect on the colloid ( such as toothpaste , shaving cream ) , with a film-forming functions , used in hairsprays, performance can be improved combing hair ; ② alginate : the case of sugar. Alginic acid and its sodium salt , is commonly used thickeners and emulsifiers , can stabilize the emulsion , has a moisturizing effect, can be used in shampoo shampoo ; ③ pullulan : also has emulsifying properties , commonly used in cosmetics clean , with moisturizing ; ④ alkyl and hydroxyalkyl cellulose : its aqueous solution with a surfactant with emulsifying and emulsion stabilizing role , and thickening and film-forming properties , including hydroxyethyl cellulose , a highly efficient thickening effect , excellent rheological strong, safe , non-toxic side effects on the skin , can be used as thickeners , emulsifiers , emulsion stabilizers and moisturizers , and is widely used in cosmetic preparations ; ⑤ cyclodextrin : the case of oligosaccharides : composed of glucose units , in a ring structure having a hydrophobic cavity which can be organic or inorganic material with many forms an envelope with other emulsifying , solubilizing and dispersing surfactant . For essential oils and flavors , has a stabilizing effect on the envelope . There are anti-foaming detergent for the role . Used in toothpaste and other oral agents, in addition to bad breath function ...... there is a special function of surfactant ; ⑥ plastic substances : secretions from trees , legume seeds, such as gum arabic , tragacanth gum, guar gum , etc. , are polysaccharides, as ancient emulsifier , can increase the viscosity of water-soluble formulation , make more auxiliary emulsifier applications.
