Abstract
The invention relates to an emulsifying agent-free protective cream. (1) The protective cream has the functions of resisting bacteria and industrial corrosive chemicals at broad spectrum, and comprises and is not limited to ethanol sanitizers, common detergent, petrochemical materials and impurities of the material, and part corrosive solvent. (2) The protective cream comprises 1-20% of polydimethyl siloxane, is insoluble in water, comprises alcohol, mineral oil and the like, has better spreadability and can easily form a hydrophobic protective film. (3) The protective cream also comprises a water-soluble film forming material, a hydrophilic film formed by the water-soluble film forming material is insoluble in alcohol, benzene, ether, acetone and the like, and the hydrophilic film is complementary with a hydrophobic layer formed by the polydimethyl siloxane, so that the hurt caused by the corrosive chemicals can be widely resisted by the protective cream. (4) The protective cream does not contain essence or an emulsifying agent, and contains an anti-inflammatory repairing agent, thus being capable of effectively repairing the hurt to the skin caused by organic solvents such as surface active agents, slightly alkaline matters, peroxide, sulfydryl derivatives and acetone.
Description
Technical field
The present invention relates to a kind of spectrum protection type cosmetics, contain hydrophilic and hydrophobic double protection membrane structure, and do not contain essence, emulsifying agent, and contain antiinflammatory reparation composition and skin care composition, to alkalescence material, acidulous material, surfactant, peroxide, sulfydryl analog derivative, ethanol, methanol, mineral oil, DMSO, benzene, ether, acetone etc. have protective action preferably, and can help to repair the skin injury that these chemical substances cause.
Background technology
Polydimethylsiloxane because its chemical inertness and preferably spreadability be widely used in general protection cream, but the spreadability of the polydimethylsiloxane of different viscosities, the compatibility of water proofing property and solvent is different.Viscosity that the present invention is preferred as hydrophobicity protecting film composition, composite in addition forms the double protection film with the hydrophilic film composition at the polydimethylsiloxane of 200cst-500cst.The hydrophilic film composition comprises: carbomer, PVA, cellulose, perhaps one or more in the polysaccharide have stronger molecular force between the preferred poly-galactoside Sulfates of polysaccharide wherein, itself and keratoprotein, can form hydrophilic protecting film closely, and have certain rub resistance.In addition, a kind of protection cream that does not contain the gel-type vehicle of emulsifying agent of exploitation that the present invention is breakthrough, safety and stability are all good, and are fit to cold allotment of labor's skill, can effectively reduce energy consumption.
Patent documentation WO90/01325 discloses a kind of waxiness that contains, the moisture barrier agent, and antiseptic, astringent, the emulsion of antibacterial by emulsifying agent and wetting agent, is uniformly distributed in skin surface with wax component, forms to stop infiltrative barrier.This invention fails to specify the kind of the harmful chemical of protection, and what adopt is emulsified body, fails to adopt hydrophobic and hydrophilic duplex film structure, has described protection cream that substantial differences is arranged with the present invention.
The object of the invention is to provide a kind of protection cream with wide spectrum protection effect of safety and stability; make the labourer who is engaged in housework or industrial labour not use glove or in the protective gloves breakage; aging; many one heavily protection under the situations such as infiltration; and by superior repairing effect, alleviate the damage that chemical substance causes.
Summary of the invention
For realizing above purpose, the present invention adopts and contains hydrophilic and hydrophobic double protection membrane structure, wherein to select viscosity for use be the polydimethylsiloxane of 50cst-1000cst to the hydrophobicity protecting film, and preferred viscosities is the polydimethylsiloxane between the 200cst-500cst, and further preferred viscosities is the polydimethylsiloxane of 350cst.Selected polydimethylsiloxane has chemical inertness, water insoluble, ethanol, and methanol, DMSO, and mineral wet goods have better spreadability and very easily form the inert protection film.The hydrophilic protecting film is selected carbomer for use, perhaps PVA, perhaps cellulose, perhaps one or more in the polysaccharide, the wherein preferred poly-galactoside Sulfates of polysaccharide.The hydrophilic film of its formation is insoluble to alcohol, benzene, and ether, acetone etc., the water-repellent layer that forms with the polydimethylsiloxane siloxanes forms complementation, thereby can extensively resist the injury of corrosive chemical.Protection cream of the present invention also contains anti-inflammatory renovation agents such as low melting point class ceramide and Hong No medicine alcohol, can effectively repair surfactant, alkalescence material, the skin injury that peroxide, sulfydryl analog derivative and acetone and other organic solvent cause.Described protection cream also contains the skin care composition in addition, as glycerol, vitamin E etc., repairs and nourishing effect except the protection effect also possesses, and also can be used as the skin-protection product of sensitivity skin.In addition, described protection cream does not contain essence, and emulsifying agent etc. have low irritability, the characteristics of low irritant.It is characterized in that: described protection cream comprises following component in percentage by weight:
Described preparation method may further comprise the steps:
(1) by described percentage by weight weighing A phase, is heated to 60 ℃ to 80 ℃;
(2) by described percentage by weight weighing B phase, and stir;
(3) A add B in mutually successively mutually and C mutually, mix and stir the back and add the D phase, the employing High shear device stirs and homogenizing homogenizing speed, mixing speed;
(4) described high temperature gel stirring is cooled to 40 ℃ to 45 ℃ and adds the E phases.
Above process is practicable preparation at normal temperatures also.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Contact the skin appearance photo of SDS under Fig. 1 is coated with protection cream and is not coated with the protection cream condition repeatedly, A is blank, and B is for being coated with the protection cream zone;
The skin haemachrome that contacts SDS under Fig. 2 is coated with protection cream and is not coated with the protection cream condition repeatedly changes;
Under being coated with protection cream and not being coated with the protection cream condition, Fig. 3 contacts the variation of the skin trans epidermal water loss rate of SDS repeatedly.
