Abstract
The invention discloses low-viscosity skin-care emulsion and a preparation method thereof. The preparation method comprises the following steps: firstly, weighing the following components by weight percentage according to a formulation: 1.0 to 3.0 percent of main emulsifying agent, 1.0 to 3.0 percent of auxiliary emulsifying agent, 0.4 to 0.8 percent of stabilizing agent, 17.0 to 27.0 percent of emollient, 0.6 to 1.6 percent of preservative, and the balance being additive and deionized water; and then adding an oil-soluble component into an oil-phase pot, adding a water-soluble component into a water-phase pot, heating the pots respectively, extracting raw materials in the oil-phase pot and the water-phase pot into an emulsifying pot to homogenate the mixture, later cooling the mixture, adding residual components into the mixture, and discharging the skin-care emulsion. The viscosity of the low-viscosity skin-care emulsion prepared by the method is between 1,500 mpa.s and 3,000 mpa.s, emulsion centrifugation does not cause oil-water separation phenomenon, the viscosity of the emulsion is affected by temperature little, and at the same time, the production method for the emulsion has the advantage of simple process and can produce the emulsion by using the prior producing technique and equipment.
Description
Technical field
The present invention relates to cosmetic field, specifically a kind of low-viscosity skin lotion and the method for making this low-viscosity skin lotion.
Background technology
Deep day by day along with what reform and open up to the outside world, the quick raising of people's living standard, the continuous expansion in cosmetics market, consumer not only proposes higher prescription to facial treatment milk, and requires also more and more harsher to product external packaging and aesthetics.Most in the market high-grade facial treatment milk all is low slimy milk liquid, and the high-grade hard material of employing is packing container such as materials such as glass, metal.Because low slimy milk liquid stability is difficult to control, the relative skin protection honey of specification requirement is higher, so high-grade mostly low sticking facial treatment milk product often sees big multinational corporations and joint brand product on the market, and domestic manufacturing enterprise is not many especially.China National Light Industrial Products Department's industry standard (QB/T2286) has strict demand to stability of emulsion: 38 ± 1 ℃ of emulsion constant temperature are after one hour, and 2000r/min is centrifugal, and the 30min emulsion must not produce oil-water separation, and this is to a strict regulations really of low slimy milk liquid.Domestic many manufacturing enterprises adopt manufacture method to have following several for making emulsion-stabilizing at present:
(1): improve emulsion viscosity, for making emulsion-stabilizing, emulsion almost there is not flowability, product can only fill in the soft package material, as plastic bottle, product uses by the extrusion plastic bottle.
(2): adopt the low slimy milk liquid of micro-emulsion technology manufacturing, but because the difficult control of manufacturing process, equipment requirements is high pressure resistant, the equipment complexity, and production cost is also higher, and this emulsion manufacturing technology is difficult in some small-sized cosmetics companies and is adopted.
(3): the low slimy milk liquid method of another kind of manufacturing is to adopt the solubilising technology, make water-fast skin protection oils and fats and essence soluble in water by the solubilising technology, this manufacturing emulsion process shortcoming is to add a small amount of oils and fats and essence, product skin moistening, skin protection fruit is bad, and too much solubilizing agent is used very big to skin irritation.
As previously mentioned, low sticking facial treatment milk can not only fill in the soft material container, also can be in top grade packing material be held by fill.Low slimy milk liquid on the market mostly is controlled in certain range of viscosities, emulsion viscosity generally is no more than 3000mpa.s, reason is when facial treatment milk viscosity is too high, in the hard material container, will can not topple over, consumer can't be used, and viscosity is not low more good more certainly, during emulsion viscosity low excessively (less than 1500mpa.s), the emulsion flowability is very good, also is not easy to consumer and uses.In addition, existing emulsion viscosity temperature influence changes greatly, is easy to cause emulsion to raise suddenly and can not pour out from rigid package in the winter time or in cold district viscosity.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of low-viscosity skin lotion, its emulsion-stabilizing, the viscosity temperature influence changes little.
Another object of the present invention provides a kind of preparation method of low-viscosity skin lotion, and its technology is simple, and production cost is lower.
The object of the present invention is achieved like this: a kind of low-viscosity skin lotion, it is characterized in that: count by weight percentage, prescription comprises following component: primary emulsion 1.0～3.0%, coemulsifier 1.0～3.0%, stabilizing agent 0.4～0.8%, emollient 17.0～27.0%, antiseptic 0.6～1.6%, all the other are additive and deionized water.
