Description

FORMULA ANTIRROZADURAS BASED ON NATURAL MATERIALS Disposable sanitary products such as disposable baby diapers, adult disposable diapers, training pants, incontinent articles, feminine towels, panty hose and other similar articles are articles intended to absorb and contain body exudates. and they are discarded after use. There are also hygienic products intended for the cleaning of intimate areas, urogenital areas and skin in general such as wet wipes. There are an infinity of proposals aimed at improving the characteristics of this type of products, some aimed at improving absorption and retention, others to eliminate run-off, some more to make the articles soft and comfortable for the user: as well as discrete, others to decrease costs, etc.

Another branch of research to improve this type of articles is aimed at protecting the user's skin, so that chafing is avoided and the skin is kept healthy and lubricated. ' For many years it has been tried to incorporate different types of lotions to the disposable hygienic products to improve the conditions of the skin during its use, example of these attempts are the patents North American US 3,585,998 to Hayford et al; US 3,464,413 to Goldfarb et al; US 3,896,807 from Buchalter; US 3,489,148 Duncan et al and many others not mentioned, these formulations have not been efficient enough so that alternatives that really protect the skin of the user have been sought. Other more recent examples of formulations used for this purpose are US Pat. Nos. 5,693,037 assigned to Procter & Gamble, which protects the use of a silicone-based surfactant; US 5,830,487 to Procter & Gamble that protects a lotion containing an organic acid such as citric acid and hydrophilic solvents such as propylene glycol so that it kills viruses and imparts softness to the top layer; US 5,869,033 EnviroDerm Pharmaceuticals protects a fabric that incorporates an organoleptic clay dispersed preferably in a matrix of superabsorbent; US 5,938,649 to Drypers Corp. protects the use of aloe vera in the top layer of a disposable absorbent article; US 6,287,581 to Kimberly-Clark protects the use, on the surface of such an article, of a hydrophobic composition enriched in lipids, comprising a natural oil a sterol, a surfactant, a humectant and an emollient, as well as many other patents not mentioned. 1 : By means of the present invention a formulation of natural origin is proposed to be applied in a disposable hygienic product that will be in contact with the user's skin in a way that protects the skin, aids in its regeneration and controls odors; The formula contains emollients and odor control agents of natural origin. Cane wax extract with recognized pharmacological properties is used - as an anti-inflammatory and healing agent. Chlorophyll or one of its derivatives is used as an odor control element. On the other hand, the addition to the formula of an antimicrobial agent such as grapefruit or grapefruit seed extract is also contemplated.

Objectives of the invention An object of the present invention is the use of a formulation to protect the skin of the wearer during the use of such disposable sanitary products, such as disposable diapers, feminine pads, pantiliners, wet wipes and incontinence articles; It also helps in dermal regeneration (healing) more efficiently than emollients currently used in these products such as vitamin E, chamomile extract or any other anti-inflammatory of natural origin.

Another object of the invention is that said formulation preferably has components of natural origin.

As additional objectives, it could be considered to include an agent that helps to control the bad odors generated by the exudates of the body, and that the formulation also helps to stop the growth of microorganisms in the article.

Detailed description of the invention Disposable hygienic products are articles that are used in contact with the body, either to receive and contain the exudates of the body or for the general cleanliness, among them we can count on the disposable diapers for babies, the training shorts, the towels feminine, pantiprotectors, wet wipes and incontinence articles. It is desirable that this type of articles help to protect the skin of the user, since the constant rubbing of the skin with the upper layer of some products and the contact thereof with moisture and feces can cause damage and discomfort for the user.

There are many proposals aimed at protecting the user's skin by using lotions containing various compounds that soften the upper layer and lubricate the skin, however none of these contemplates the use of elements of natural origin mixed in a solution so that they act together to lubricate and regenerate the skin in an efficient way as well as to eliminate the characteristic odors of exudates from the body.

The present invention protects the use of the extract. , of cane wax in a solution that may contain a natural element for odor control such as chlorophyll or its derivatives and an antimicrobial agent such as grapefruit or grapefruit seed extract, so that the solution is applied to the product Disposable hygienic in order to protect the skin of the user, help in its regeneration in case of damage, control odors and stop the microbial development.

The extract of cane wax is recognized by its pharmacological properties as a cicatrizant, anti-inflammatory and antimicrobial. '! ! ' The extract of cane wax helps accelerate »the keratinization of the dermis and increases the level * of moisture in the skin leaving the skin soft and elastic. . ,; Said extract is obtained as a by-product in the production of sugarcane, it is a liquid of uniform appearance, a faint green color with a characteristic odor and is composed of a mixture of fatty acids: myristic, palmitic, stearic, arachic, dodecanoic), higher alcohols (tetracosanol, hexacosanol, octacosanol and triacosanol) and phytosterols (stigmasterol, campesterol and beta-cytosterol) among others.

In the proposed formula, the extract of cane wax or its derivatives are efficient used in amounts ranging from 1.0,% by weight.

Chlorophyll or its derivatives such as copper chlorophyll, sodium or potassium, are natural adsorbents, so that, by means of Van der Waals forces, they attract two odor-generating compounds, which adhere to the chlorophyll molecule and become trapped. in it, chlorophyll and its derivatives have been recognized for being powerful deodorantes, such that, when used together with natural extracts such as cane wax extract, you get a solution that also helps to lubricate and regenerate the skin, neutralizes bad odors. ·: ·: In the proposed formula, chlorophyll or its derivatives are efficient used in amounts ranging from; 0.01% by weight. : The antimicrobial agent such as grapefruit or grapefruit seed extract has antimicrobial activity against most Gram-positive, Gram-negative, fungal and yeast bacteria, another characteristic additional is its anti-inflammatory activity since it has been shown to be a potent inhibitor of cyclo-oxygenases and lipoxygenases, enzymatic keys of arachidonic acid metabolism, resulting in reduced formation of proinflammatory metabolites.

In the proposed formula, the antimicrobial agent based on grapefruit or grapefruit seed extract is efficiently used in amounts ranging from 0.01% by weight.

As a vehicle for the solution, pharmaceutical grade propylene glycols (USP) such as monopropylene glycol can be used instead of water to avoid; the growth of microorganisms.

According to the above, the formula proposed to be applied in disposable sanitary products contains at least 1.0% by weight of cane wax extract; and at least 1% by weight of vehicle. In addition, the formula can be added with an odor eliminating agent such as chlorophyll or derivatives in a concentration in amounts ranging from 0.01% by weight and an antimicrobial agent, such as grapefruit or grapefruit seed extract. , in amounts ranging from 0.01% by weight.

In general, to this type of articles you will add some fragrance to make them more attractive to the consumer, the same can be contained in the proposed formula in amounts ranging from 0.01% by weight, so that in a single operation the emollient formula and the fragrance are added to the product.

The proposed formula is applied to disposable sanitary products in amounts ranging from 0.06 g / cm 2.

Examples The formula below was experimentally tested under the following conditions and with the following results: Proposed anti-chaffing formula with healing effect Percentage Minimum Compound (%) Cane wax extract i. ,: 5: 00 Chlorophyll or its derivatives .0.05 Extract of grapefruit or grapefruit seeds 0: 5 Mono propylene glycol 94.45 Experimental development This formula was tested by the experimental method 240416-3 CIDEM, IPN 1994, which consists of using 30 male Swiss coballes housed in individual cages for 21 days with controlled temperature of 22 ± 2 ° C, humidity of 40-60% and light cycle / darkness | of 12/12 h.

All the animals were depilated 24 h before, to make the cut in the scapular region, in an area1 of 2 x 2 cm2, which included skin and subcutaneous cellular tissue. ' The application of the emollient to be evaluated was carried out daily for a period of 21 days, the time of appearance and fall of the scab and cicatrization of the area during the entire experimental period was observed.

Conclusion · | It can be concluded that the emollient with 5% cane wax extract was effective in wound healing developed in experimental animals and that: a. the four days of the test had already crusted the "80% of the animals and after 21 days had healed" 90%, while for the samples placebo (only vehicle) after four days had crusted only 10% of the animals and 21 days had healed 10% of: the animals.

With the placebo sample without extract or vehicle, after four days, zero% of the animals were crusted and 21% of the animals healed after 21 days.

We also carried out use panel studies where 50 users of the economic segment size 4 (babies with presence of irritation) were contacted, 25 users tested sample A containing the proposed scarring formula and the remaining 25 sample B as a control; Two deliveries of 10 diapers were made to each participant, explaining the dynamics of the study.

From the panel study of use it can be verified that sample A has a very high proportion with respect to sample B in terms of the reduction of irritation, in the first and second delivery of the sample. While; Sample B in the two deliveries has the same presence of decrease in irritation, much less than that presented by sample A.

While the invention has been described in terms of a presently preferred embodiment, it is clear that various changes and modifications may be made therein, such changes and modifications being within the scope of the invention, as defined in appended claims.
