- step (c) cut the bar obtained in step (b) to obtain a solid composition according to the invention.
- this process for manufacturing a composition according to the invention comprises at least the steps consisting of:
- (a) have a fatty phase, a phase deriving from a saponification reaction and/or a phase comprising at least one synthetic detergent (or surfactant) (ie SYNDET phase), in liquid or semi-liquid form. liquid ;
- step (b) passing the phase of step (a) through an extrusion device provided with a die (or extrusion grid) of suitable shape to form a solid bar, and
- step (c) cutting the solid bar obtained in step (b), whereby a composition according to the invention is obtained.
- step (b) is carried out at a temperature adapted to have a composition with sufficient viscosity and capable of retaining the shape assigned by the die.
- the shape of the die of the extrusion device is also adapted to ensure the formation of the cavities.
- step (b) is carried out at a temperature below ambient temperature, and for example at a temperature less than or equal to 15°C, or even less than or equal to 10°C.
- the extrusion device comprises a die with a shape adapted to form the cavity(ies) and the desired level of porosity at the level of the solid bar.
- an extrusion process comprises a die such as that illustrated in Figure 4.
- Step (c) can be carried out using a knife or a wire, such as for example a butter cutting wire.
- steps (b) and (c) are simultaneous.
- the process for manufacturing a composition according to the invention is extrusion process no. 2 described above.
- step (i) / (a) consists of having a fluid composition which can comprise at least one solvent capable of evaporating in all or part during step (ii) / (b), or even additionally during step (iii) and/or (iv) / (c).
- a solvent we can for example cite a non-polar or slightly polar organic solvent, for example cyclohexane, THF (tetrahydrofuran), and their mixture.
- a non-polar or slightly polar organic solvent for example cyclohexane, THF (tetrahydrofuran), and their mixture.
- step (i) / (a) may require heating said composition to a temperature greater than the highest melting point of the lipophilic gelling agents present in said composition.
- extrusion process no. 2 can be carried out using a 3D printing technique.
- a composition according to the invention is dedicated to the hygiene and/or beautification of a keratin material, in particular of the skin and/or hair.
- a composition according to the invention is dedicated to the hygiene of a keratin material, in particular of the skin and/or hair, such as for example toothpastes, deodorants, shower gels, intimate cleansing gels. , soaps, shampoos, mouthwashes, hair care products (hair dyes and bleaches), hair care products, cleaning products, shaving and depilatory products, such as for example aftershave, depilatory creams and shaving creams, bath and shower preparations, such as for example bubble baths, bath oils and bath salts.
- a solid composition according to the invention is a soap and/or a shampoo.
- a solid composition according to the invention is not in the form of a mask.
- a solid composition according to the invention is intended to be brought into contact with an aqueous phase, in particular water before, simultaneously and/or after its application to the keratin material to be treated.
- a composition according to the invention is of the single-dose type
- the contact with water is extemporaneous, that is to say just before use and/or simultaneously if applied to a wet keratin material.
- a composition according to the invention when a composition according to the invention is not of the single-dose type, the contact with water is carried out during the first use only, and requires conditioning of the mixture " solid/water composition” in a suitable receptacle.
- this requires a solid composition of suitable formula and a sufficient quantity of water to ensure the transition from a solid composition to a liquid composition, for example in gel form.
- this requires the presence in the solid composition of at least one preservative to guarantee good preservation over time of the liquid composition thus formed.
- the present invention also relates to a non-therapeutic cosmetic treatment process for hygiene and/or beautification of a keratin material, in particular of the skin and/or hair, comprising at least one step of application on said keratin material of at least one composition as defined above.
- Figure 1 represents a composition according to the invention in a parallelepiped shape with a cylindrical-shaped cavity.
- A is the side view and B is the top view.
- Figure 2 represents a composition according to the invention in an ovoid shape with cavities (view from above), representing the word “SOAP”.
- Figure 3 represents a composition according to the invention provided with honeycomb cavities (view from above).
- Figure 4 represents a die used for the process of the invention.
- Figure 5 represents a comparative sector.
- Figure 6 represents other examples of solid compositions according to the invention.
- Step 1 - manufacturing
- step 1 The mixture C obtained in step 1 is injected into an extruder provided, in a first case, with a die according to the invention as illustrated in Figure 4 and in a second case, with a comparative die as illustrated in Figure 5;
- Step 3 is carried out on a panel of 18 women and 18 men between 22 and 47 years old (hereinafter the “candidates”), 3 groups then being formed, each group being made up of 6 women and 6 men (groups A, B and C).
- Each of groups A, B and C will use soaps 1, 2 and 3, but each time in different orders.
- candidates evaluate the performance of soaps 1, 2 and 3 in terms of (i) gripping capacity, (ii) foaming capacity (iii) condition of the soap after use. Rating criteria :
- the soap according to the invention 1 makes it possible to combine the advantages of classic soaps 2 and 3 without their disadvantages.
- a composition according to the invention thanks to the presence of cavities in the contents considered, allows access to solid compositions capable of generating more foam with less material while generating less loss, and this without prejudice to the properties of grip.
- a solid composition according to the invention therefore requires less raw materials and is therefore advantageous both ecologically and economically.
- SYNDET also referred to as “soap-free soap” or “dermatological bar”
