Description

Lead of cosmetic pencil

Technical field

Being used to of using in liner, lip liner, eye shadow product, eyeliner, Kajal pen, Lipstick holder etc. decorates and the lead of cosmetic pencil of skin nursing purpose.When saying at this and during pen core, will be understood that chalk also belongs to this type of.This lead of cosmetic pencil contains pen core base material and oil, filler and the pigment of being made up of waxy substance such as wax, fat and emulsifying agent usually.

Disadvantageously, it has relatively low heat stability and particularly low maximum applied temperature in such pen core.At this, the maximum applied temperature is meant such temperature, promptly just still pen core material or chalk material can be coated on lip, eyelid or other parts of skin under this temperature, and pen core do not appear and smear confusion, distortion, perhaps pen core or chalk fractures.Though common pen core has 60 ℃-90 ℃ fusing point or fusion range, their maximum applied temperature is much lower naturally.Be used to form pen core method affect the micro structure of pen core base material, therefore influenced the machinery of the pen core that formed afterwards and used characteristic.The influence of dump method is minimum, and can produce application temperature with the method is about 40 ℃-45 ℃ pen core.In pressing method, the pen core starting material is compressed in cylinder and it is extruded with the rope form form through delivery outlet, if the pen core base material is subjected to the load of machinery and heat by this way, the pen core for preparing only has about 30 ℃-35 ℃ application temperature.

Summary of the invention

From this point, task of the present invention is, a kind of pen core that is used for cosmetic applications is provided, and this pen core is being improved aspect its heat stability, particularly can use under higher temperature.

This task is resolved by the pen core according to claim 1.The pen core base material of predesignating pen core like this is that oil or waxy substance form by the lipophilic substance of at least a soap and at least a fusion range＜50 ℃.At this, such material can be thought the pen core base material, and promptly this material is as the binding agent of solid particle, and uses characteristic and heat stability decisive role for pen core.

Show astoundingly, can prepare the pen core that fusing point surpasses 90 ℃ with such base material, therefore this pen core can withstand the storage temperature more much higher than common pen core harmlessly, and can promptly be higher than in the temperature higher than common pen core under 50 ℃ the temperature and use.In addition surprisingly, the pen core with the pen core base material that is provided can hold the solid particle until 90%, can prepare the very high pen core ingredients of color intensity thus.Can not prepare such pen core with common pen core base material.Because the high-load of solid particle, the pen core material that therefore becomes molten condition has too high viscosity, so that it can't pour into.But, in pressing method, be shaped or by for example extrusion molding also is impossible by means of extruser, because the liquefaction too consumingly under required temperature of common pen core base material.In contrast, pen core material of the present invention can be extruded on no problem ground under about 80 ℃-about 140 ℃ temperature, except other this be because pen core material or pen core base material this under this temperature, still have sufficiently high processing viscosity.With containing 1%-20%, the pen core of the soap of preferred 3%-10% can obtain good especially result.Adopt the fatty acid salt content of 4%-8% can obtain best result.The content of lipophilic substance is 5%-40%, preferred 10%-35%.The lipophilic substance content of 16%-32% is verified to be specially suitable.

At least 50%, the solid content of better 60%-90% has advantageously influenced the heat stability of pen core, has particularly influenced the application temperature of pen core.At this, think filler such as Talcum and Muscovitum and for example pigment all belong to solid particle.At first preferred lead of cosmetic pencil form is made up of 1-20% soap, 5-40% lipophilic substance, 30-90% solid particle, 0-10% additive, and further preferred pen core form is made up of 4-8% soap, 16-32% lipophilic substance, 60-80% solid particle, 0-10% additive.

Soap deemed appropriate soap, particularly calcium laurate, magnesium stearate, zinc stearate with chain length of 10-20 carbon atom, and palmitate, myristate, oleate and linoleate.Specially suitable is the mixture of lithium stearate, aluminium stearate, Aluminium Tristearate Micronized sterile and described soap.Can obtain optimal results with aluminium distearate.

Following material can be used as lipophile liquid or have＜50 ℃ low-melting oil or waxy substance: and Oleum Ricini, mineral oil, stearyl dimethicone, hydrogenation (sclerosis) Oleum Cocois, isopropyl palmitate, isopropyl myristate, triglyceride such as tricaprylin and decanoin, hydrogenated palm kernel oil-glyceride and hydrogenated palm oil-glyceride also have olive oil, Oleum Brassicae campestris and other to be usually used in the oil of cosmetics.

Can add be usually used in cosmetics the organic or inorganic pigment as coloring agent.It is also conceivable that the use dyestuff in addition, for example the lipophilic dyestuff.In needs, can consider absorb fillers, for example Talcum, Kaolin, Muscovitum or be coated with the Muscovitum of silicon dioxide.In needs, can add the one-tenth structural agent or the one-tenth of antiseptic, sunscreen, aromatic substance, vitamin, spice, care substance and low content and organize agent such as C 30-45 alkyl methyl siloxanes (CAS Nr.131459-42-2) as additive or auxiliary agent.At this, be 10% to the maximum in the total amount of additives in raw materials.

Material of the present invention is homogenized in mixer, kneading compactor, roller base etc., and be extruded into pen core or chalk in 80-140 ℃.

As basic recipe, can provide following composition:

Soap: 1-20%

The lipophilic substance of fusing point＜50 ℃: 5-40%
