Description

Wrinkle cosmetic product.

The present invention relates to a product anti-wrinkle cosmetic, suitable for application to a skin that it presents wrinkles and bags, in order to provide smoothness and smoothness to said skin.

Currently, most products Cosmetics are particularly used for an application in the skin of the face, which presents wrinkles and bags, in order to tersar and give more smoothness to said skin. However, these products do not eliminate wrinkles and bags completely, to the extent that this effect can only be obtained by means of one or more surgical interventions. The present invention relates to a new type of wrinkle cosmetic product, provided with a different composition with respect to the cosmetic products used in the prior art, and comprising a reduced number of components that allow a wrinkle effect to be obtained Complete and excellent on the skin on which they are applied.

The cosmetic product is made with the composition described below, making reference in particular to the appended patent claims. The invention it will become more clear from the description Next of this cosmetic product.

The wrinkle cosmetic product according to the invention comprises a wrinkle tensioning agent that includes the silica and water which are the two main components that act As an active ingredient, able to provide smooth skin uniform and smooth, being able to complement these components also with the excipients described below.

In particular, silica is a pyrogenic silica amorphous that normally acts as a thickening agent but has discovered that said silica, surprisingly, is suitable for act as a tensor agent, that is an agent that is used to tersar the skin and therefore is used herein Invention with this function. The silica is formed by spherical particles having a diameter between 7 and 40 nm, whose surface is constituted by siloxane groups (Si-O-Si-O-Si-) and silanoles (-Si-OH) with a greater amount of siloxane groups, which means that this compound is inert. The silica, when surrounded by water molecules, such as in the present combination of the two main components silica and water, forms a gel-like structure. The two components of silica and water combined in this way can be used as a system or solution sol, a system or gel solution, or a system or spray solution

The two main components can be combined or mix at room temperature, with a percentage of silica preferably between 0.1% and 3% by weight with respect to weight of the resulting composition and with a percentage of water between 99.9% and 97% by weight with respect to the weight of the resulting composition, water can be added to the composition in smaller percentages if one or more excipients are added to said composition.

The present composition may be added to some excipients that develop particular functions and that are, for example, of the following types:

a) moisturizing agents;

b) soothing agents;

c) humidifying agents;

d) emollient agents;

e) refreshing agents;

f) thickening agents;

g) preservative agents;

h) stabilizing agents;

i) film forming agents.

The following describes, by way of example, at least one possible agent and its weight percentage for a eventual use for each excipient.

a) moisturizing agent: Panthenol from 0.1 to 3 per weight percent; 0.5 to 3 percent sodium hyaluronate in weight;

b) calming agent: Ethoxyglycol, Caprilil glycol, sodium polyacrylate, each presenting 0.1 to 3 per weight percent;

c) humidifying agent: Glycerin, Propylene Glycol, presented each 10 to 30 percent in weight;

d) emollient: Dimethicone copolyol 0.1 to 5 per weight percent;

e) cooling agent: Aloe barbadensis 0.5 a 3 percent by weight;

f) thickening agent: xanthan gum from 0.1 to 3 per weight percent;

g) preservative agent: as in b)

h) stabilizing agent: Algin from 0.1 to 3 per weight percent;

i) film forming agent: 0.1 to 3 agar weight percent

Obviously others can also be used excipients, combined in different percentages by weight with silica and water, and therefore without departing from the scope of this invention.

By way of example only, they are detailed Here are other excipients that can be used:

- Disodium edta of 0.1 to 1 percent in weight;

- Salicylic acid of 0.1 to 0.5 percent in weight;

- Sodium alginate, Osmocide, etc.

The composition prepared in this way, when It is applied to the skin, forms a homogeneous film and causes the skin absorbs it and that it is terse and gain smoothness, producing by consequently the tensor effect. In addition, this composition, thanks to the ability to retain water, provides a moisturizing effect on the skin surface, with an improvement in its aesthetic appearance (smoother and more uniform skin) while thanks to a pH slightly acidic allows biological balance to be preserved of the skin.
