CN105106984A - Preservative-free facial mask sterilizing process - Google Patents

Abstract

Disclosed is a preservative-free facial mask sterilizing process. The process is characterized by including: 1), placing a facial mask which is encapsulated and thermally sealed well and does not leak liquid into a sterilizing machine; 2), heating and pressurizing; 3), stopping heating, feeding cooling water or cooling liquid for cooling, and controlling balance between pressure inside and pressure outside the facial mask; 4), waiting until temperature in the facial mask reaches normal temperature; 5), allowing standing for 20-28h; 6), repeating steps 1)-5) for 1-3 times; 7), finishing sterilization when the temperature of the facial mask reaches the normal temperature; 8), after sterilization, directly using the facial mask for external packing. The preservative-free facial mask sterilizing process has the advantages that adding of preservatives is not needed to guarantee quality and quality guarantee period of the facial mask, so that raw material cost is saved, and the facial mask is free of preservative adding and more natural; temperature, time and pressure are selected for balance, and balance between pressure inside and pressure outside the facial mask is controlled by cooling, so that expanding and breaking of a facial mask bag are avoided. By the preservative-free facial mask sterilizing process, batch sterilization can be realized, the facial mask bag is free of deformation, expansion and breaking, the facial mask is absolutely sterile, and product quality and quality guarantee period are guaranteed.

Description

A kind of without anticorrosion facial film sterilization process method

Technical field

The invention belongs to a kind of Biocidal treatment method without anticorrosion facial film.

Technical background

In mask product, because water content in facial film is very many, easily by microbial contamination, so have higher requirement to sterilizing and antiseptic power.Existing facial film has adopted antiseptic usually, and antiseptic as protecting product from microbial contamination, going bad, extends the shelf life of product for the application of face pack prescription inhibitor effectiveness.But be unwanted contributions itself for skin protection, even may increase the zest of skin and cause allergy etc.; For guaranteeing the safety of product, in order to prevent consumer from causing possible infection because using the product by microbial contamination, if the amount that antiseptic adds is inadequate, then may occur that microorganism adapts to growing environment around, develop immunity to drugs, thus cause anticorrosion inefficacy.Desirable antiseptic should have spectrum activity, can make faster microorganism deactivated, formulation stable, life-time service safely, have no stimulation and sensitization.In general, most of antiseptic or effective or effective to antifungal to antibacterium, can not be simultaneously effective to both; Be that Compositional antiseptic agent is more on the market at present.Antiseptic is useless to skin protection itself, can increase the zest and sensitization etc. of skin even on the contrary, the burning sensation that such as phenoxyethanol produces, Methylisothiazolinone (MIT) issuable allergy etc.Therefore existing cosmetics relevant laws and regulations require the also clear stipulaties addition requirement of regulated substance (antiseptic).At present in mask product is produced, employing be traditional pressure sterilizing process, the shortcoming that this method exists to make the mounted facial film in face cause facial film bag deformed dilation, fracture phenomena.

Along with Cosmetics in China consumption consciousness successive Regression script and natural safe theory, " zero adds " " zero burden ", " not adding antiseptic " etc. more and more come into one's own and praise highly, especially along with facial film fast sale in recent years, the development and application of sterilization technology plays a part more and more important to cosmetics safety and natural research and development field

Summary of the invention

Object of the present invention provides one not add any antiseptic to overcome the defect of above-mentioned prior art existence just, can directly as the mounted facial film in face without anticorrosion application, reach sterility requirements, effectively stop microbial contamination on the impact that product causes without anticorrosion facial film sterilization process method.The present invention have selected the equilibrium relation between more suitable temperature, pressure, time three, does not produce the swollen bag of facial film and breaks, make facial film reach sterility requirements, and product quality and shelf-life reach 6-36 month and be protected.

The object of the invention is to realize by following technical solution.

A kind of without anticorrosion facial film sterilization process method, feature of the present invention is:

1) fill has been sealed without leakage facial film and put into sterilizer;

2) temperature-pressure, temperature is 60 DEG C-200 DEG C, and pressure is 0.4-13 atmospheric pressure, constant temperature 10-180 minute;

3) stop heating, enter cooling water or liquid coolant cooling, it is 0.2 DEG C-0.6 DEG C/min that rate of temperature fall controls, and controls the intrinsic pressure and outer pressure balanced of facial film;

4) treat that face temperature in the shed is to room temperature;

5) 20-28 hour is left standstill;

6) as above 1)-5) step operates repetition 1-3 time again;

7) facial film temperature reaches room temperature, and sterilizing terminates;

8), after sterilizing, outer package is directly used in.

The invention has the beneficial effects as follows, quality and shelf-life that this technology does not need to add antiseptic and ensures facial film, economize in raw materials cost, make product " preservative free interpolation " more natural, selective temperature, time, pressure balance, cooling controls the intrinsic pressure and outer pressure balanced of facial film and does not make facial film bag shape produce swelling fracture; The present invention can realize bulk sterile, and facial film bag is without deformed dilation, fracture phenomena, and facial film absolutesterility, product quality and shelf-life are protected.

Detailed description of the invention

1) fill has been sealed without leakage facial film and put into sterilizer;

2) temperature-pressure, temperature is 60 DEG C-200 DEG C, and pressure is 0.4-13 atmospheric pressure, constant temperature 10-180 minute;

3) stop heating, enter cooling water or liquid coolant cooling, it is 0.2 DEG C-0.6 DEG C/min that rate of temperature fall controls, and controls the intrinsic pressure and outer pressure balanced of facial film;

4) treat that face temperature in the shed is to room temperature;

5) 20-28 hour is left standstill;

6) as above 1)-5) step operates repetition 1-3 time again;

7) facial film temperature reaches room temperature, and sterilizing terminates;

8), after sterilizing, outer package is directly used in.(as mounted box vanning etc.).

Embodiment one

Fill sealed, sterilizer temperature-pressure put into by without leakage mounted facial film, and temperature is 200 DEG C, and pressure is 0.6 atmospheric pressure, constant temperature 20 minutes; And then adopting cooling water or liquid coolant cooling, it is 0.6 DEG C/min that rate of temperature fall controls, and controls the intrinsic pressure and outer pressure balanced of facial film, until face temperature in the shed reaches room temperature, leaves standstill 26 hours; As above program operates repetition 1 time again, and till facial film temperature reaches room temperature, sterilizing terminates.

Embodiment two

Fill sealed, sterilizer temperature-pressure put into by without leakage mounted facial film, and temperature is 150 DEG C, and pressure is 6 atmospheric pressure, constant temperature 100 minutes; And then adopting cooling water or liquid coolant cooling, it is 0.2 DEG C/min that rate of temperature fall controls, and controls the intrinsic pressure and outer pressure balanced of facial film, until face temperature in the shed reaches room temperature, leaves standstill 22 hours; As above program operates repetition 3 times again, and till facial film temperature reaches room temperature, sterilizing terminates.
