Abstract
Description
- This invention relates to a product for permanent shaping keratin fibres consisting of a packaging and a ready to use aqueous composition comprising at least one reducing agent.
- It is generally known that permanent shaping is carried out in two steps, the reductive splitting of the cystein disulfide bonds in the hair by a reducing agent and the subsequent neutralisation by application of an oxidizing agent, whereby the cystein disulfide bonds are restored.
- The reducing agent used still most frequently is thioglycolic acid also in the form of the salts thereof, in particular its ammonium salt, although numerous other thio compounds have been proposed for this purpose which, however, mostly have not been successfully applied because of toxicological reasons. The reducing agents especially of interest are thiogylcolic acid, cystein, thiolactic acid and cystamine. Another one is glycerine monothiogylcolate (GMTG) showing very good permanent shaping effect, however, has some toxicological problems. The reducing agents are in general used at a concentration of 1 to 20% by weight, preferably 1 to 15% by weight. It should be noted that regulations on the concentration of reducing agents must be followed in those countries where authorities do so.
- Compositions for permanent shaping hair are usually packed as single dose units because of their sensibility to oxidation when contacting air. Multi-portion products are as well available although the great stability concerns. Once products is opened and emptied partly, remaining product is losing its effect as a reducing agent and this certainly affects the results of the permanent shaping process. In order to overcome such stability problem, pressurised packaging materials have found their application which often requires use of flammable propellants limiting their effective use as packaging for permanent shaping products. Therefore, there is a great need for multi-portion products for permanent shaping hair. Products as single does units brings certainly high packaging costs and waste, which is, in addition, not always environmental friendly. Additionally, usually because of stability reasons, they have to be packed into a multi phase products, which are mixed prior to application. This requires as well expensive special packaging technology, which brings certainly limitations in practice.
- It is, therefore, highly desirable to achieve ready to use products, without any mixing step prior to use, for permanent shaping hair, especially from the view point of a multi-portion product, with low cost without loosing the performance in terms of stability and permanent shaping ability during whole life time of the product. This invention starts form the problems as explained and aims primarily for finding an alternative, which is more cost effective and environmental friendly and as well be packed without using propellants. The alternative packaging makes withdrawal of content of package in smaller portions than the whole content of the product without affecting the stability of the remaining product
- It has now been found out that a multiportion permanent shaping ready to use product can be achieved by using a tube or a pouch confectioned with a cap which releases its content when a pressure is applied and closes without sucking gas from its environment. This form of preparation show advantages over the conventional packaging has been used until now as well as over aerosol packaging proposed to solve stability problem in the literature. Product for permanent shaping is released from packaging as it is without forming foam.
- With the term permanent shaping throughout the description and as well with the claims, the reference is made to perming and straightening processes.
- The inventors have surprisingly found out that the use of a twist cap (A) on a tube (7) or a pouch packaging component (8) or a bottle consisting of a seal (1), temper evident (2), thread (3) and a carrying element (4) and confectioned with a silicone valve (5) and a retainer therefore (6) filled with a permanent shaping composition solves the above mentioned problems. Packaging with such kind of closure cap have been proposed in a US patent application published US 2003/0106910 A1.
- Accordingly the object of the present invention is product for permanent shaping hair consisting of a packaging and an aqueous composition wherein packaging is consisting a twist cap (A) on a tube (7) or a pouch packaging component (8) or a bottle consisting of a seal (1), temper evident (2), thread (3) and a carrying element (4) and confectioned with a silicone valve (5) and a retainer therefore (6) filled with a permanent shaping composition comprising at least one reducing agent.
- Further object of the present invention is multiportion product for permanent shaping hair consisting of a packaging and an aqueous composition wherein packaging is consisting a twist cap (A) on a tube (7) or a pouch packaging component (8) or a bottle consisting of a seal (1), temper evident (2), thread (3) and a carrying element (4) and confectioned with a silicone valve (5) and a retainer therefore (6) filled with a permanent shaping composition comprising at least one reducing agent wherein the composition can be removed partially without effecting the stability of the remaining product.

- Filling of the aqueous composition into tube or pouch for obtaining product comprising at least one reducing agent for permanent shaping hair is carried out in a process in which the compositions is filled into the tube or pouch with an extendable filling nozzle entering into pouch or tube in order to secure the long lifetime of the content (reducing agent comprising composition for permanent shaping hair) - long-term stability.
- The following examples are used to illustrate the invention, but not limit it
Example 1 % by weight Ammonium thiogylcolate 9.5 Ammonium hydroxide (25%) 6.6 Ammonium carbonate 1.0 Cremophore RH 60* 1.5 C12-C16 alkyl polyglucoside 1.5 Fragrance q.s Water to 100 - * Ethoxylated hydrogenated castor oil
- The composition of example 1 was filled into the tube as described above. The product was stable over the period of 12 weeks (period tested) at 40°C and at room temperature. No instability is observed in terms of perming performance on hair, which was shown in a comparative permanent shaping test on hair switches, where the permanent shaping was carried out with a product as above aged and a freshly prepared composition. In the perming process, as an oxidation agent 2.3% by weight hydrogen peroxide comprising oxidizing agent is used.
- In another test the same product was filled into a packaging with a volume of 500 ml according to the invention and in a bottle without containing the silicone valve, meaning that when the cap is opened the content is directly in contact with air. Both products were stored at room temperature and their content was emptied every week by removing 50 ml. With the removed composition perming test was carried out as described above. Comparison was also made with a freshly prepared composition. The evaluation was carried out by a hair dresser according to following scale.
- 1 no permanent shaping at all (no curls observed)
- 2 slight permanent shaping (slight waves)
- 3 permanent shaping (waves)
- 4 good permanent shaping
- 5 very good permanent shaping
- The results are presented in Table I.
Table I: Results of permanent shaping test of the products stored in different packaging as described above and a freshly prepared permanent shaping composition. Storage Example 1 stored in according to (see above) Period (weeks) Invention Comparative Fresh composition 1 5 5 5 2 5 4 5 3 4 3 5 4 5 3 5 6 4 1 5 - From the above results it is clear that the composition stored in a packaging according to invention shows very good perming performance and therefore without loss of its thiogylcolic acid content, whereas the composition stored in a bottle with a cap without silicone valve did not show any permanent shaping effect after storing 6 weeks at room temperature indicating that the reducing agent thioglycolic acid is not stable under those conditions. Thus, the product of the invention has a longer shelf life than that of comparative product.
- Similar results are obtained with the following examples as well.
-
% by weight Ammonium thiogylcolate 5.0 Cystein 2.5 Ammonium hydroxide (25%) 3.2 Cremophore RH 60* 1.5 Oleyl polyglucoside 0.5 Fragrance q.s Water to 100 *Ethoxylated hydrogenated castor oil - The preparation and filling and perming tests were carried out as above. No instability was observed.
-
% by weight Thiolactic acid 12.5 Ammonium hydroxide (25%) 9.0 Ammonium bicarbonate (25%) 5.0 Urea 4.0 Polyquatenium-6 0.5 Cocobetaine 0.8 Fragrance q.s Water to 100 - The preparation and filling and perming tests were carried out as above. No instability was observed.
