Method for producing a pomade effect based on a single-phase, foam-forming hair treatment composition

Abstract

The method of obtaining a pomade effect on hair includes providing a foam pump apparatus for making a foam from a single-phase composition, which contains at least one anionic, carboxylate-group containing surfactant compound, preferably a sulfosuccinate, and at least one nonionic emulsifier; then generating a foam from the single-phase composition by operating the foam pump apparatus; and working at least a portion of the foam into the hair without subsequently rinsing the hair in order to provide the pomade effect.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The subject matter of the present invention is a method of treating hair with a foam made from a single-phase, foam-forming hair treatment composition to produce a pomade effect, especially a fixing effect and luster in the treated hair.

2. Prior Art

Research in the field of hair treatment compositions has included study of preparations in the form of pomades for many years. These pomades facilitate hair shaping and increase the luster and hold of a hairstyle. Pomades are usually applied as non-transparent masses in the form of creamy emulsions or gels. However the emulsions or gels are difficult to distribute evenly on the hair, so that hair styling is difficult, especially when only small sections of the hair are treated with this agent.

The products conventionally employed to produce a pomade effect, which means to simultaneously produce an intense luster and hold, have a high proportion of water-insoluble materials, such as fatty bodies. Because of these fatty bodies however the hair is strongly loaded and the product is removed only with difficulty by means of a shampoo to the extent that the hair does not have a residue. Furthermore this type of product suffers from the problem of undesirable separation of water and fat phase.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a method with which an intense pomade effect can be obtained, whereby the typically negative or poor properties of the prior art compositions, such as poor distributability on the hair, strong load of the hair, poor washability from the hair and phase separation of the product are avoided.

Pomade in the form of foam that breaks up when worked into the hair or on styling the hair offers a better possibility for application to hair.

Low or average viscosity masses with pomade properties can be applied with the help of aerosol foam. The advantage of a propellant aerosol product is that it is very easy to produce foam with it, even with small amounts of only poorly foaming contents. It is however a disadvantageously difficult problem to stabilize the propellant gas in the aqueous phase for packing the composition as a single-phase product. Phase separation can change the properties important to the composition's action as a pomade as well as its aesthetic properties. If the aerosol product should be packaged in a transparent container, only glass is considered for use as a packaging material. The packaging of an aerosol product in a glass container however results in a potential safety problem or a risk.

Foaming without propellant gas occurs in a simple way by the use of a strongly foaming surfactant compound selected from the classes of anionic surfactants, amphoteric surfactants or nonionic surfactants. The disadvantage of using these surfactants in concentrations which are required so that the pomade composition will be in the form of a foam is that when the foam composition is applied to the hair it does not break up. Furthermore an after-foaming occurs on the hair, as it does similarly with a shampoo, which is undesirable for application of a pomade. Furthermore pomade masses, which contain large proportions of these surfactants are too viscose to guarantee that good foaming action can be obtained without the help of a propellant gas. Dilution with organic solvent leads of course to a reduction in viscosity, however a drastic reduction in foamability also occurs because of the dilution. If the pomade composition is diluted with water until it reaches a viscosity at which it is easy to form foam, this leads to a reduction in the pomade effect.

According to the invention these difficulties are overcome by providing a product or article of manufacture for hair treatment consisting of

A) single-phase composition containing

a1) at least one anionic, carboxylate-group-containing surfactant compound, and

a2) at least one nonionic emulsifier; in combination with

B) an apparatus for making a foam from the single-phase composition (A).

The composition provides outstanding foam without the use of a propellant gas and can be worked into the hair satisfactorily without a disturbing after-foam formation. It imparts good shapability, a long-lasting luster and a long-lasting soft feel to the hair.

The carboxylate-group-containing surfactant compound or compounds is or are preferably present in the composition in an amount of from 0.1 to 30 percent by weight, especially preferably in an amount of from 1 to 10 percent by weight. The preferred carboxylate-group-containing surfactant compound or compounds is or are sulfosuccinate or sulfosuccinates, sulfosuccinamate or sulfosuccinamates, carboxylated fatty alcohol ethoxylate or ethoxylates, carboxylated fatty acid amide ethoxylate or ethoxylates or their mixtures.

When R 1 —X represents an alkoxylated or non-alkoxylated alkyl citrate group, it is preferably in the form

COMPARISON OF THE PROPERTIES OF VARIOUS FOAM COMPOSITIONS INCLUDING DIFFERENT SURFACTANT COMPOUNDS

The following hair treatment-relevant properties of the following compositions were determined. The hold of the hair style, its luster, the extent of undesirable after-foaming on working the foam in the hair, foam quality 15 seconds after foam production and foamability of the composition with the help of a foam pump were measured. The measurements were made by testing individual criteria by five persons independently. A value of 1 for a property means ‘very good’ while a value of 6 means ‘unusable’.

Table I shows the composition of the six tested compositions A, B, C, D, E and F. The amount of active surfactant plus emulsifier was maintained constant for all compositions, except for composition F. The ingredients of the compositions were labeled with numbers and a key showing the relationship of the ingredient number to the ingredient is provided here: (1), Arlatone® G; (2), REWODERM® S1333; (3), Ampho Betaine AM®; (4), Texapon® N 70; and (5), Oramix® NS 10.

A sample of the foam compositions receives an evaluation of ‘good’ for the property ‘foam quality after 15 seconds’ when it is as fine-pored as possible 15 seconds after its production and prior to working into the hair and when it breaks up as little as possible. Compositions C, D and E foam very strongly on working into the hair (shampoo effect) so that cleaning of the hair would be required.

The composition according to the invention corresponding to recipe B has essentially better properties for hair treatment than those of the composition A which only contains a nonionic surfactant ingredient and does not have the disadvantages of compositions C, D and E.

When the compositions B, C, D and E are compared with composition F, in which the active content of the Arlatone® G is the same as that of compositions B to E, the fact that the hold of the hair style and luster obtained with composition B according to the invention is significantly better than the other compositions is established.

This German Patent Application describes the invention described hereinabove and claimed in the claims appended hereinbelow and provides the basis for a claim of priority for the instant invention under 35 U.S.C. 119.

While the invention has been illustrated and described as embodied in a single-phase, foam-forming hair treatment composition for producing a pomade effect, it is not intended to be limited to the details shown, since various modifications and changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.

What is claimed is new and is set forth in the following appended claims.
