Description

  The present invention relates to a topical skin-care formulation (TSF) and dipped elastomer rubber polymer products made using TSF. The present invention particularly relates to a dipped elastomer rubber / polymer glove manufactured using TSF and TSF.

  When wearing disposable rubber gloves, especially when wearing rubber gloves for a long time, a physiological phenomenon occurs in which the hands sweat inside the gloves. Such damp conditions are typical conditions that cause skin irritation. Under these conditions, if bacteria or fungi are attached to the skin of the hand, these will proliferate, and the moisture will cause materials such as surfactants, chemical residues, and proteins to ooze out from the inner surface and base of the glove. There is a possibility. This condition ultimately causes skin irritation. Therefore, there is a need to provide a suitable coating agent for gloves in order to protect hand skin from inflammation and improve the overall comfort felt by the glove wearer.

  By using an approved powder such as starch having excellent absorbency, moisture is absorbed and the comfort felt by the glove wearer is improved. However, when the glove is worn for a long time, the problem is not solved. Users wear antiseptic cream or protective cream before wearing gloves, and in addition to this, gloves that are pre-coated with various lotions and additives are produced.

  US Pat. No. 6,274,154 describes a glove using a Barbados aloe solution in which the prepared barbados aloe solution is applied to the inner surface of a glove made of natural rubber and nitrile rubber. Barbados aloe is one of the folk remedies and is well known for its healing effects on burns, scratches and sunburn. Since the effectiveness of Barbados Aloe is reduced when exposed to air, even if a stabilizer is added to the Barbados Aloe extract, it is better to cut the planted Barbados Aloe and use it directly.

  The majority of gloves currently in use are low-cost disposable medical gloves, and ideally, the additives used to improve wearer comfort and hygiene are economically realistic. It must be true. That is, in order for glove coated for skin care to be sold at a reasonable price, these additives must be low cost materials or be effective in very small amounts.

  What is important in common with any applied coating is that it does not have any detrimental effect on the quality of the glove. The coating should not cause defects such as small blisters or holes in the glove or any significant effect on the physical properties of the glove, both before and after the glove has been worn for a long time. The coating agent should also not tend to propagate bacteria and fungi in some species of plant extracts that can cause glove contamination during glove storage.

  Therefore, vitamins A and B are coated on the surface of immersion elastomer, rubber and polymer products such as gloves and condoms to protect the human skin coming into contact with the inner surface of the immersion elastomer, rubber and polymer products and to obtain comfort. And a partial skin care formulation (TSF) comprising an effective amount of E, alpha lipoic acid, eucalyptus oil, jojoba and a carrier.

  Also contains effective amounts of vitamins A, B and E, alpha lipoic acid, eucalyptus oil, jojoba and moisturizing carrier to protect human skin in contact with the inner surface of the dipped elastomer, rubber and polymer products and to provide comfort. A dipped elastomer, rubber, polymer product, such as a glove or condom, with a partial skin care formulation (TSF) layer is provided.

A step of preparing a partial skin care formulation comprising an effective amount of vitamins A, B and E, alpha lipoic acid, eucalyptus oil, jojoba and a moisturizing carrier, the carrier comprising a dipped elastomer, rubber and polymer product In the final stage of manufacturing, the elastomeric rubber polymer product is immersed in a partial skincare formulation or applied to the surface of the elastomeric rubber polymer product by an off-line coating application process. A partial skin care formulation in contact with the surface of the elastomer, rubber and polymer product,
The surface of the elastomer, rubber and polymer product is evaporated by evaporating the moisture of the partial skin care formulation by transferring the coated elastomer, rubber and polymer product soaked in the partial skin care formulation to the drying process. Comprising substantially uniforming the upper partial skincare formulation layer and cooling the coated elastomeric rubber polymer product immersed in the partial skincare formulation to room temperature.
A method is provided for the production of elastomeric rubber polymer products such as gloves or condoms that are dip coated in a partial skin care formulation.

  In addition, a partial skin care formulation containing effective amounts of vitamins A, B and E, alpha lipoic acid, eucalyptus oil, jojoba and a moisturizing carrier is applied to the surface of a dipped elastomer, rubber or polymer product such as a glove or condom. It provides a carrier application that makes it possible.

  The present invention comprises a combination of some novel features and details fully described below and the parts set forth in the appended claims, and various modifications of the details of the invention depart from the scope of the invention. It is understood that this can be done without sacrificing any advantage of the present invention.

Preferred embodiment

  The present invention relates to a partial skin care formulation (TSF) and an elastomer rubber polymer product produced by dipping in TSF. In particular, the present invention relates to a dipped elastomeric rubber polymer glove manufactured to be integrated with TSF and TSF.

  This specification describes the invention below according to preferred embodiments of the invention. However, the fact that the description is limited to the preferred embodiments of the present invention is only for the convenience of the description of the present invention, and those skilled in the art will appreciate that various modifications can be made without departing from the scope of the appended claims. And equivalents can be devised.

  The invention described is a coating agent called Partial Skin Care Formulation (TSF), which is a disposable rubber glove made from natural rubber, various synthetic rubbers or blends of these rubbers. Applied to the mounting surface.

ビタミンＡ，Ｂ及びＥ、及びαリポ酸は、肌の酸化的老化から肌を守る効果のある抗酸化特質で知られている。ユーカリ油は多くの製剤において防腐剤としてよく知られ、また冷却効果もあり、一方、ホホバは保湿及び鎮静(soothing)効果を有している。 Table 1 shows a typical composition of components before drying of TSF applied to the surface of an immersion elastomer / rubber / polymer product. After drying, the moisture evaporates and there is no moisture on the soaked elastomeric / rubber / polymer product.

Vitamin A, B and E, and alpha lipoic acid are known for their antioxidant properties that have the effect of protecting the skin from oxidative aging of the skin. Eucalyptus oil is well known as a preservative in many formulations and has a cooling effect, while jojoba has a moisturizing and soothing effect.

  Various methods of applying a coating on a powderless disposable glove that can be manufactured by many different methods will now be briefly described. The coating can also be applied to powdered disposable gloves.

  Once coated with TSF, the coating agent is released from the inner surface of the glove to the wearer's hand skin through moisture (sweat) from the wearer's hand. At this time, the wearer can get a pleasant feel and the TSF can release moisturizing, protective and antiseptic properties.

  As mentioned above, the present invention also uses a carrier to enable the use of TSF. The carrier ensures uniform distribution of all components of the TSF to obtain a uniform distribution of the components of the TSF when the TSF is coated on a dipped elastomer, rubber or polymer product such as a glove or condom. Is necessary. Emollient cream is selected as a carrier for the constituents of TSF and as a moisturizing cream to provide a more comfortable softness to the skin.

  Details of an example of a method of manufacturing a rubber glove coated with skin care are as follows.

Example 1
Gloves are manufactured using conventional “powdered” gloves manufacturing methods. These gloves made of natural rubber, nitrile rubber, polyisoprene rubber, or blends of any of the aforementioned rubbers are chlorinated. This treatment is usually performed off-line using a specially designed machine during which the powder is removed from the glove and the chlorine chemically reacts with the rubber surface. This treatment is a single chlorination cycle or two chlorination cycles in which the gloves are flipped after the first chlorination cycle. In a single chlorination cycle, the glove is usually placed so that the glove's wearing surface is on the outside of the glove, and then the glove is turned over before or after the drying step.

  In such processes, chlorinated gloves are typically subjected to multiple water washing cycles at the final stage of the process to remove unwanted chemicals on the gloves. At this time, a suitable concentration of TSF can be added to the water and a water-based dispersion of TSF can be included in the final wash cycle so that the gloves are completely and evenly coated with TSF.

  After immersion of the TSF in the aqueous dispersion, the excess dispersion is removed by draining and gentle centrifuging of the gloves. The final stage involves a drying process in which the gloves are dried for 1 hour at a temperature of 50 ° C. to 90 ° C. in a suitably designed natural dryer.

(Example 2)
The glove may be coated by an online dipping process, in which the glove is dipped into the aqueous dispersion after all post cure leaching is complete. The gloves are then dried online at temperatures up to 120 ° C., cooled and removed. Such gloves typically use a coagulation system that does not require powder, so that the glove does not require any off-line process other than a drying process. Such gloves are coated with a polymer by an off-line process or subjected to on-line chlorination and then dried before being immersed in an aqueous dispersion of TSF. After soaking in TSF, the gloves are passed through a drying kiln set at a temperature of 80 ° C. to 120 ° C. before being removed.

(Example 3)
It is also possible to coat the gloves with TSF online by following the same process steps as in Example 2 and dipping in an aqueous polymer dispersion containing TSF.

Example 4
After the final rinsing step of online chlorination, the gloves can also be coated online by immersing them in a tank containing an aqueous dispersion of TSF. In this example, the gloves are not dried before being dipped into the TSF dispersion. After being lifted from the TSF dispersion, the gloves are passed through a drying kiln set at a temperature of 80 ° C. to 120 ° C., cooled, and finally removed.

(Example 5)
The gloves may be coated by spraying a fine mist of an aqueous dispersion of TSF onto the surface of the glove in a tumbler dryer. If the glove is turned over during this process, the mounting surface will be on the outside and coated with TSF. The temperature of the dryer ranges from 50 ° C to 90 ° C. This method is applicable to either powdered or powderless gloves.

(Example 6)
Powdered gloves coated with TSF can also be produced. TSF coating is done by incorporating the TSF dispersion into the final wet powder slurry, so that the mounting surface is coated simultaneously with the powder and TSF.

  After the moisture in the dispersion has evaporated during the drying process, a glove with a uniform coating of TSF, which is essentially a uniform residual coating on the glove surface, is applied to the rubber glove mounting surface by any of the methods described above. Can be manufactured. When wearing gloves, part of the TSF is released from the surface of the glove and comes into contact with the wearer's hand skin, producing a soothing effect and a degree of protection from bacteria and skin inflammation. According to the extensive test results of gloves coated with TSF, TSF material can be measured on the quality of gloves made of natural rubber, nitrile rubber, polychloroprene rubber, polyisoprene rubber or blends of these rubbers It has been shown that it does not have any harmful effects.

  Various types of gloves and methods that take advantage of the inner surface of the gloves coated with TSF have been described above. This does not necessarily include all of the methods for manufacturing coated gloves, and there will probably be other individual manufacturing techniques in this extensive glove industry.

In the foregoing specification, the invention has been described with reference to specific preferred embodiments thereof, and has been described in detail for purposes of illustration. However, for those skilled in the art, the invention is susceptible to additional embodiments. It will be apparent that the specific details described herein are capable of modification without departing from the basic principles of the invention.
