Description

252510?

  The invention relates to the field of cosmetics, more particularly to a new form of conditioning

bath preparations.

  The subject of the invention is new bath preparations in water-soluble sachets comprising a cosmetic base

  fluid contained in a bag made of a polyvinyl alcohol film.

  vinyl. The invention also relates to the following additional characteristics, considered individually or in all their technically possible combinations: the cosmetic base is anhydrous at 9 or more, the cosmetic base is a foaming bath, the cosmetic base is an oil foam bath, -the cosmetic base is a bath oil, -the polyvinyl alcohol film has a thickness of between about 30 and 50 microns and a weight per unit area of between about 40 and 60 g / m The invention especially relates to a preparation as defined above wherein said cosmetic base, anhydrous at 90%, is a bubble bath, a foaming bath oil

or a bath oil.

  Since the earliest times, the bath is not limited to the only cleaning of the body The baths are more and more taken for reasons of body care, medical treatment or for the pleasure of being in contact with this natural element What is water The temperature of the water cools or warms, the cleaning and care combined with products

  for the bath and the fragrance that emerges from it vivify, rafrat-

chit and relax.

  At present, the sector of cosmetic preparations for the bath knows a strong development, in particular that of the bubble baths These products consist essentially of synthetic surfactants and water as shown in the formula. type given below: Surfactants 15-50% Fatty acid alkylamides 5-10% * by weight Water 30-60% Preservative O 1 1% Softening agent 1-5% Fragrance 1-5% Coloring q s. Mostly present on the market in liquid form, foaming baths are generally packaged in bottles of various capacities, with or without a measuring cap, or in tubes, more particularly when it comes to

gels.

  Given the presence of water in high proportion in such products, one is forced to store, transport and pack large volumes of liquids to use

  in fact only about half of these in the form of

  active ingredients The presence of water, moreover, requires the use of preservatives intended to prevent the proliferation

  of microorganisms being stored.

  The use of bottles with measuring cups makes it possible to add to the bath water the quantity of suitable product.

  of these, however, often leads to fouling.

  These bottles, whose outer surface then becomes rapidly sticky, are progressively gradual, even if the dosing cap is rinsed after use, there is still the risk of reintroducing water into the bottle, thus diluting its contents and decreasing accordingly. efficiency,

  when used at equal volume.

  The invention provides a novel mode of packaging that makes it possible to easily overcome the disadvantages inherent in the use of the preparations known to date, particularly

bubble baths.

  The new preparations according to the invention are in the form of water-soluble sachets, intended to be added to the bath water at the beginning of the filling of the bath.

  consist of a bag itself made of polymeric material

  water soluble, polyvinyl alcohol (PVA) in this case,

  and containing a fluid cosmetic base.

  Compared to other water-soluble polymeric materials, such as polyolosides for example, PVA has the advantage

  to be perfectly soluble in the bath water. It is also

  easy to weld, which allows the realization of bags using the usual technological means, such as a simple

pulse welder for example.

  PVA films are also impervious to gases and perfume vapors, resistant to greasy substances, in particular

  those used in cosmetics and stable vis-à-vis the light

  The PVA also has the advantage of being well tolerated by the

  skin and mucous membranes, and is fully biodegradable

  From the point of view of cosmetics, PVA enables the manufacture of soft and translucent pouches that are soft to the touch and can

  to be shaped in any imaginable form.

  PVA films used for the manufacture of sachets

  water-soluble compounds according to the invention are available on the

  marketed and obtained from specialized manufacturers.

  Their thickness will be determined in particular by the tensions

  they will have to bear, as well as by the speed of dissolu-

  The results were obtained by the use of thick films.

  approximately 35 microns for a weight per unit area

of 45 g / m 2 (density 1.28).

  According to the invention, the cosmetic base packaged in

  PVA is a fluid, anhydrous 90% or more base.

  In fact, it has been found that below this limit

aesthetic, PVA.

  The fluid cosmetic base may be a foaming bath, a foaming bath oil or a bath oil for example, it is obtained from the ingredients commonly used in

  art It can be perfumed and colored at will and

  additionally contain skin care products such as softeners or superfatting agents If desired, it may be further incorporated opacifiers or nacrants;

  contrary, the said base will preferably be perfectly trans-

  cide. Given the low water content, the use of preservatives is no longer necessary. The base is further protected from external contamination by its individual packaging. The basic volumes used are almost halved. o less space,

  especially during the storage of the water-soluble sachets.

  The new bath preparations according to the invention are in the form of dose-units, adapted to the standard volume of the baths. These doses, preferably perfumed

  at a rate of 6 to 10% by weight, weigh from 10 to 15 g approximately.

  With a small footprint and easily transportable, they are particularly appreciated for the supply of

  hotel rooms for example, for the trip as well.

  The formulation of the fluid cosmetic bases used in the new bath preparations according to the invention can be drawn from the specialized literature / see, for example, Dehydag Information Edition 04/78, published by Henkel K Ga AD Usseldorf-RFA 7. will give some examples,

EXAMPLE

  PVA film: 35 micron g / m 2 1.28 density obtained by calendering, from commercial PVA powder; Manufacture of the bag From the PVA film mentioned above, a sleeve 4 cm wide, measured flat, was prepared. The sleeve thus obtained was then welded at one end and then

  filled with a fluid cosmetic base of bubble bath type.

  The desired unit doses were then obtained by welding the thus filled sleeve at regular intervals, approximately every cm. Each unit thus prepared weighed about 14 g. All the welds were made using a

commercial pulse welder.
