Abstract
The invention belongs to the technical field of production of cosmetics and relates to new application of ethyl cellulose aqueous dispersion in preparation of cosmetics. The ethyl cellulose aqueous dispersion is mainly formed by mixing ethyl cellulose, a stabilizer and water and has the thickening, suspending, bonding, emulsifying, film forming, dispersing, water holding and colloid protecting effects when being used for preparation of the cosmetics, so that the bottleneck that the ethyl cellulose aqueous dispersion is insoluble in water and can not be widely applied to the cosmetics is solved; meanwhile, the new application of the ethyl cellulose aqueous dispersion in the preparation of the cosmetics is safe and easy.
Description
Technical field
The invention belongs to Cosmetic Manufacture technical field, relate to the new purposes of Aquacoat for Cosmetics Production.
Background technology
At present; a lot of for the preparation of the raw material type with water conservation, thickening power of cosmetics both at home and abroad; wherein cellulose family macromolecule material has good thickening, suspension, bonding, floatingization, film forming, dispersion, water conservation and protective colloid action is provided with it; in market, occupy important share, this current series products mainly comprises methylcellulose, ethyl cellulose, hydroxyethyl-cellulose and hydroxypropyl emthylcellulose etc.Comparatively speaking, ethyl cellulose and hydroxyethyl-cellulose are a kind of good colloid thickening agents, water holding capacity exceeds one times than methylcellulose, there is good flow adjustment, it is the poorest that dispersibility and generally acknowledged methylcellulose and hydroxypropyl emthylcellulose are compared dispersibility, but protecting colloid ability is the strongest; And relative hydroxyethyl-cellulose, ethyl cellulose has nonflammable, Heat stability is good, good thermoplasticity, to daylight invariant color, pliability is good, dielectricity is good, have good alkali resistance weak acid resistant, anti ageing property is good, the resistance to good hygroscopicity of salt tolerant tolerance to cold, stable to chemicals, long term storage never degenerates, can be with many resin compatibilities, have the advantages such as good compatibility with all plasticizers, but be dissolved in the physical property of organic solvent because ethyl cellulose is water insoluble, greatly limited its application at cosmetic field.
Summary of the invention
In order to solve problems of the prior art; the invention provides the new purposes that Aquacoat is prepared for cosmetics; described Aquacoat is mainly mixed by ethyl cellulose, stabilizing agent and water; for cosmetics preparation process, play thickening, suspension, bonding, floatingization, film forming, dispersion, water conservation and protective colloid action is provided.
