Description

Cosmetic and anti-aging stockings or tights impregnated with natural slow-release substances and its manufacturing process

The subject of the invention is a pantyhose or pantyhose, or any textile support in direct contact with the skin, cosmetic and anti-aging impregnated with natural substances with slow release and its manufacturing process.

According to the invention, the natural substances or active principle are contained according to one embodiment in the extracts of algae and iridaceae.

Algae extracts have the function of oxygenating the skin tissues and increasing the elasticity of the skin.

Iridacea extracts provide zinc and vitamin A. Zinc as a coenzyme takes part in the enzymatic reactions intervening during cell growth and the regeneration of damaged tissues by activating the healing process.

Vitamin A is one of the essential agents of cell growth by inducing cell multiplication.

The extracts of algae and iridaceae act in synergy to have an anti-radical action. The algae extracts are extracted from ulva lactuca. The extracts of this alga protect and reinforce the elastic properties of the skin.

The subject of the invention is also the manufacturing process which allows the stockings or tights, or any textile support in direct contact with the skin, to be impregnated with natural substances with slow release.

The manufacturing process consists, after the dyeing stage, of acting during the softening process by incorporating a combination of biomimetic phospholipids into the conventional softening bath.

The combination of the biomimetic phospholipid components is as follows:

A) Phospholipid GLA (Sodium Borageamidopropyl PG-Dimonium Chloride Phosphate) at 0.5% of the bath

B) Phospholipid PTC (Cocamidopropyl PG-Dimonium Chloride Phosphate) at 1.5% from the bath

The primary function of this combination of phospholipid components is to promote "anchoring" or impregnation of the active ingredients by an electrostatic process, and the secondary function of being an antibacterial agent which controls the bacterial flora.

To these two phospholipid components are added the natural substances to the active ingredient for a maximum total of 2.10%. The softening and impregnation phase lasts about 35 minutes at a temperature between 35 ° c and 37 ° c.

The proportion of fabric softener solution, including the phospholipid components, the active products, must be a proportion of 10 to 1, that is to say for 10 kg of solution, one kilogram of tights must circulate in a bath.

According to a preferred embodiment, the active principles or natural substances are the following:

A) Seaweed from 0.7% to 1.00% maximum

B) U a Lactuca from 0.3% to 0.5% maximum

C) Iris Florentina from 0.3% to 0.5% maximum

D) 0.1% fragrance essence For a maximum total of 2.1%.

According to another embodiment, the active ingredients are as follows: A) Ginseng from 0.25% to 0.35% maximum B) Ginko Biloba from 0.25% to 0.35% maximum

C) Hydrocotyle from 0.25% to 0.35% maximum

D) Green tea from 0.25% to 0.35% maximum

E) Aloe (Aloe Vera) from 0.50% to 0.70% maximum For a maximum total of 2.10%.

General description of the invention:

Properties of seaweed and flora extracts and their impact on a new generation of tights or any textile support in direct contact with the skin.

The invention relates to the properties of tights, or any textile support in direct contact with the skin, making it possible to use the substances contained in the extracts of algae and iridaceae which, during usual use, are released on skin contact.

These stockings and tights, or any textile support in direct contact with the skin, offer a soothing, decongestant, hydrating and above all anti-aging cosmetic advantage, properties obtained by the substances contained in extracts of algae and iridaceae. They also benefit from the efficiency, in synergy, of these substances alone or associated with other ingredients and those useful for their manufacturing process.

The algae belong to the group of chlorophyllous thallophytes, that is to say from the large family of cryptogams or plants without flowers, generally classified according to the color: green algae (chlorophyceae), brown (pheophyceae), red (rhodophyceae), and blue (cyanophyceae).

Rich in vitamins, mineral salts, antioxidants, capable of binding and promoting the elimination of polluting substances, they stimulate metabolism thanks to their iodine content. They help improve the general physical appearance.

Seaweed is used in many forms in the industrial and agricultural world. In addition, they play a nutritional role in the treatment of certain conditions due to nutritional deficiencies and / or linked to metabolic imbalances. Given the high iodine content, certain brown algae (kelp and fucus) were already used in the 17th century in the treatment of goiter and in Graves' disease.

These different physiological effects explain the prescription of algae in diseases and syndromes such as: iodine metabolism disorders, organic deficiencies, deficiency of vitamins or trace elements, rickets, obesity, rheumatic, arteriosclerotic sites, various infections, intestinal parasitoses, certain disorders of the urinary tract, gastritis, colitis, circulatory disorders. In addition to the nutritional properties, algae are also finding increasing use in cosmetic care, in particular for their soothing, emollient and purifying qualities.

Here are some very often used algae and their assigned functions:

The use of algae in cosmetics has indeed increased over time.

The dermatological properties derive from a series of active substances, including: antioxidant vitamins, for example provitamins A and D and vitamin

VS ; specific hydrating and mucilaginous biopolymers; different biologically active secondary metabolics.

Currently used cosmetic products containing algae include: cleansing milk, toner, moisturizer, deodorant, hand, face and body cream, intimate cleanser, shampoo; as well as specific bath products, useful preparations to fight cellulite, stretch marks, acne problems and help improve the skin appearance.

The anti-cellulite treatment in thalassotherapy uses sea water rich in typical trace elements in association with different types of seaweed. It can be carried out with specific cosmetic preparations and is possibly developed by the topical application of preparations based on algae as such or in the form of extracts, such as mud, masks and other local extemporaneous applications.

The drawback of the cosmetic formulations currently used is linked to the time of application and to the contact with the skin surface, which is necessarily dependent on limited periods during the day.

The invention resides in particular in the fact of impregnating active substances on a support such as stockings or tights or any textile support in direct contact with the skin.

Stockings and tights, or any textile support in direct contact with the skin, are an ideal support for prolonging the cosmetic effects of our algae and iridacea preparations over time because they are in permanent contact with the skin and guarantee the beneficial properties of the active substances by their prolonged and progressive release. This represents an innovation in the sector.

Indeed, substances of different types of algae and iridaceae are used to be absorbed and deposited on the surface and inside the textile fiber of the stockings or of the pantyhose or any textile support in direct contact with the skin.

Different species of algae allow a particularly interesting application. For example:

Brown algae: Fucus, Pelvetia, Ascophyllum, Himanthalia, Laminaria, Sargassum species.

Red algae: Chondrus, Mastocarpus or Girgatina, Palmaria, Porphyra, Ceramium and Gracilaria.

Green algae: Ulva, Enteromorpha and Codium.

The following varieties of algae are also cited: Ascophyllum nodosum, Pelvetia canaliculata, Enteromorpha, Palmaria palmata, Sargassum muticum, Ceramium rubrum, Gracilaria verrucosa, Ulva lactuca, Laminaria digitata, Codium.

All algae have significant anti-radical and anti-aging behavior. In particular, brown algae, including Fucus vesiculosus.

According to a preferred embodiment, the alga chosen is Ulva lactuca which contains the same amounts of vitamin A as cabbage and C of oranges and moreover a wide spectrum of group B vitamins. We find a high content of salts minerals and trace elements: iodine, bromine; Ca, Mg and K; Mn, who can explain some of their anti-allergic effects.

Ulva lactuca is also rich in amino acids (proline, glycine and lysine) which have an important role in maintaining skin elasticity.

A full spectrum of the composition of Ulva Lactuca is described in Table I.

The algae extracts used in the context of this invention are prepared by conventional liquid phase extraction methods, including the use of supercritical fluids.

For extraction by aqueous means, it is carried out with a pH controlled by specific buffer solutions. The extraction is also done by the use of polar solvents, which are either used together or in combination with an aqueous medium.

The final manufacturing phases consist in dehydrating the extract, by concentration under vacuum, or by reverse osmosis, or by concentration and purification by chromatography or ultrafiltration. In special cases certain substances isolated from algae extracts are obtained by chemical synthesis, for example fucoli, polifucoli, difloretoli, polifloretoli, bifualoli, polifualoli and floretoli, which have remarkable anti-radical activity. Therefore, in this description the term "algae extract" is used in general to describe substances isolated from these extracts or obtained by chemical synthesis.

The algae extracts used, to impart a cosmetic action to stockings and tights, or any textile support in direct contact with the skin, are associated with iridacea extracts.

Among the Iridaceae it is particularly preferred the Germanic Iris Florentine variety, which is rich in polyphenols, flavonoids and anthocyanins with high antioxidant action, therefore with an important antioxidant activity. In order to develop the anti-aging properties of the devices which are the subject of the invention, the substances contained in the algae extracts are combined with one or more antioxidants.

The antioxidants suitable for our purpose include, in a non-exhaustive manner, the antioxidants contained in the seeds, leaves, flowers and bark of fruit and plants, and can be of extractive origin from natural bottoms or synthetic origin equivalents.

Representative antioxidants are certain amino acids (e.g. histidine and valine), flavonoids (e.g. armadendrine, morine, quercitrine, esperetine, naringenin, kaempferol, apigenin, luteolin, fosetin, fustin, rutin, miricetin), anthocyanins ( ex: pelargonidine, cianidine, delfinidin), catechins (ex: catechin, epicatechin, gallocatechin, proanthocyanosides), carotenoids and retinoids (carotene isomers, licopene, xanthine, retinol, cataxantine), tocopherols (ex: alfa-beta - and gamma-tocopherol), tannins (e.g. gallic acid, propyl gallate and gallic esters, tannic acid), phospholipids (e.g. egg and soy lecithin), L-ascorbic acid and esters, alfa- hydroxy acids (e.g. lactic acid, citric acid, L-tartric acid) polyascides of Monascus red, peanut and rice substances (e.g. cardanol, cardol, anacardic acid, oryzanol, mahogany oil), thiodiproprionic acid and lauric ester (DLTBP), alfa-lipoic acid, nordihydroguaiaretic acid (NDGA), guaiacol, hydroxytirosol and olive oil esters (ex: oleuropene, verbascoside), other phenols of spices and herbs (ex: rosemary, cloves, chilli, cinnamon, ginger, paprika (TBHQ), citrus oils, trihydroxybutirophenol (THBP), BHT and BHA), maclurine, ethoxyquin, ellagic acid, musizine, boldine, but also their corresponding glucosides, esters and ethers, and their combinations. Among the particularly preferred antioxidants are gallic acid and its derivatives, ascorbic acid and its derivatives, but also the flavonoids contained in plant extracts or in purified form.

Other types of active ingredients with adjuvant and / or synergistic function are also used in the present invention.

Although not limited to these categories, general examples include anti-wrinkles and anti-inflammatories.

Examples of anti-inflammatory drugs include licorice derivatives, flavonoids, alfa-bisabolol, rosemary, azulene, asiaticoside, ruscogenin, escin, betulinic acid and its derivatives.

Examples of anti-wrinkle are retinol, tocopherol, salicylates and their derivatives.

For the production of tights, or any textile support in direct contact with the skin, object of the present invention, several of these methods can be used.

Anchoring with polymeric gels or resins including the active ingredients (algae and synergistic agents), the deposition of microcapsules, impregnation, precipitation or surface absorption, for example by using suitable surfactants.

Cationic, nonionic, anionic, amphoteric surfactants and combinations thereof are also usefully used.

Among the surfactants, mention is made of: nonionics: alcohol alkoxylate and fatty or sorbitan acids, polyoxypropylene and polyoxyethylene, alkyl polyglycosides; anionics: fatty acid soaps, sodium lauryl sulfate or lauryl ether sulfate, alkyl benzensulfonates, mono and or dialchil phosphate and the like; amphoterics: dialchilammine oxides, different types of betaines, phospholipids and natural ceramides.

Among the surfactants, preference is given to biomimetic phospholipids (products of Mona, USA), substances of glycerophosphocolinic nature with a cationic charge.

In addition, the device which is the subject of the invention is treated with substances with anti-prolific action on different species of microorganisms, for example with the external alkyls of p-hydroxybensoic acid, idantoin, paraben, imidazolidinil urea, sodium dehydroacetate. , benzyl alcohol and a range of quaternary ammonium components, in addition to inorganic or mixed substances such as iodine and mercury components.

Sunscreens can be incorporated into the softening bath and active products, for example PABA derivatives, benzophenone, and cinnamati, in an amount depending on the degree of ultraviolet protection desired.
