Abstract

The invention relates to a hair care product for caring for hair, which contains specific amounts of C2-C6-monohydroxy alcohols, C8-C20 alkanes, C8-C24 alcohols and cationic surfactants, and which transforms into a cream, a lotion or a gel when coming into contact with water.

Description

2021P00090WQ - "Transformative Hair Care"

The present invention relates to hair treatment compositions for hair care, comprising an active substance combination of specific alcohols, alkanes and cationic surfactants. The invention further relates to a method for caring for hair using the hair treatment agent.

Over time, and especially with longer hair, damage to the hair fibers occurs. Damage is understood to mean both damage caused by friction damage such as combing, brushing, backcombing and structural or chemical changes in the hair fibers, which can be caused by processes such as dyeing, bleaching or permanent deformation. Sun exposure, environmental influences or (heat) styling can also damage the hair fibers.

Dry or damaged hair can be treated with standard leave-on or rinse-off care products, which contributes to a significant improvement in the inner and outer hair structure.

However, the needs of the consumers and also the know-how of the cosmetics manufacturers change or improve and require or enable a constant improvement and adaptation of existing hair care products.

Hair care products available on the market usually include a combination of different care ingredients such as cationic surfactants and polymers, oils of different polarity, silicones, etc., which have to be laboriously stabilized in a usually aqueous base. On the one hand, this requires higher energy consumption and, on the other hand, the stabilization of water-insoluble care ingredients in particular requires the additional use of synthetic auxiliaries, which are increasingly undesirable.

There is a need for less complex, innovative, fast-acting, simple and versatile application forms for hair care with high hair care potential.

The aim of the present invention was to provide such hair care formulations.

The goal is achieved according to the invention by a hair treatment composition for hair care which--based on its total weight--a) 20-40% by weight of at least one monohydroxy alcohol, b) 10-45% by weight of at least one C8-C20 alkane , c) 5-30% by weight of at least one C8-C24 alcohol and d) 0.1-5% by weight of at least one cationic surfactant.

The hair treatment agents according to the invention have the advantage that, due to their thin consistency, they can be removed from the packaging easily and with little residue, and spread quickly and very well to the ends of the hair. In combination with water, they transform into a cream, lotion or gel, which adheres to the hair even after a short exposure time and promotes good separation of the care ingredients. The hair treatment compositions according to the invention are particularly suitable for use as a rinse-off composition.

Hair treated with compositions according to the invention has a healthy, well-groomed appearance and a pleasant feel. In particular, they are easy to detangle and have very good combability in wet and dry hair, a well-groomed and supple hair feel right down to the hair tips, radiant shine and anti-frizz. A weighing down of the hair could not be observed even with regular use of the compositions according to the invention.

In addition, compositions according to the invention can be produced, packaged and transported in a resource-saving manner because they contain no or only a small amount of water.

The hair treatment agents according to the invention can be applied to the hair with a conventional conditioning agent immediately after the hair has been cleaned or after it has been cleaned and cared for. Alternatively, the hair treatment agents according to the invention can also be used as pretreatment agents before cleaning the hair.

The hair treatment compositions according to the invention can be applied to the towel-dried and/or moist keratin fibers.

The invention also relates to a hair treatment composition as described above, comprising (based on the total weight of the hair treatment composition): a) 20 to 40% by weight of at least one C2-C6 monohydroxy alcohol.

C2-C6 monohydroxy alcohols a) support the dissolution or solubilization of water-insoluble components in the hair treatment agents according to the invention, so that preferably transparent compositions can be provided.

The hair treatment agent according to the invention is preferably in the form of a low-viscosity solution and/or dispersion and is preferably transparent.

Such a product form can be manufactured, packaged and transported in a resource-saving manner, has no instabilities and has a number of practical advantages. For example, it can be easily removed from the packaging with little residue and distributed very well in the hair fibers. It is also advantageous that the care substances in the hair treatment compositions according to the invention are not bound in a solid matrix and therefore quickly reach the hair fibers. In addition, low-viscosity products are perceived as light, modern and yet caring and the transformation from "transparent, clear liquid" to "white cream or lotion" is visualized particularly well. “Low viscosity” preferably means a viscosity in the range from 1 to 1500 mPas, more preferably 5 to 1000 mPas. The viscosity was measured using a Haake model VT 550 rotational viscometer at a temperature of 20° C. and 8 rpm.

For the purposes of the present invention, “transparency” means that the hair treatment agents do not scatter light in the range that is usually visible to humans.

The hair treatment agent according to the invention can preferably be applied directly to the hair—preferably with the aid of an application bottle.

Alternatively, the composition of the present invention can be applied in the form of a spray-on hair treatment and sprayed onto the hair. The spray can be a pump spray or atomization can be achieved with the aid of propellants. Suitable propellants (propellant gases) are propane, propene, n-butane, isobutane, isobutene, n-pentane, pentene, isopentane, isopentene, methane, ethane, dimethyl ether, nitrogen, air, oxygen, nitrous oxide, 1,1,1,3-Tetrafluoroethane, heptafluoro-n-propane, perfluoroethane, monochlorodifluoromethane, 1,1-difluoroethane, more precisely either individually or in combination. Hydrophilic propellant gases, such as carbon dioxide, can also be used advantageously provided the proportion of hydrophilic gases is selected to be low and a lipophilic propellant gas (e.g. propane/butane) is present in excess. Propane, n-butane, isobutane and mixtures of these propellants are particularly preferred. It has been shown that the use of n-butane as the sole propellant can be particularly preferred. Receptacles made of metal (aluminium, tinplate, tin), protected or non-shattering plastic, or glass coated on the outside with plastic may be used as compressed gas containers; Compressive strength and breaking strength, corrosion resistance, ease of filling, as well as aesthetic aspects, handiness, printability, etc. play a role in their selection.

A further possibility consists in mixing the hair treatment composition according to the invention with water in a suitable container, shaking it and applying it to the hair as an emulsion in a conventional manner.

The combination of the essential and optional ingredients described makes it possible to provide hair treatment agents that can be applied easily and quickly and can be applied to the entire length of the hair right down to the tips of the hair.

Contact with water (e.g. by wetting the hair in the shower) transforms the hair treatment agent according to the invention into a cream, a lotion or a gel which can be massaged further into the hair and the care effect can be felt.

It has been found that the hair treatment agents according to the invention and their specific application promote the deposition of care substances on the hair fibers, so that a lasting conditioning effect can be achieved. To prevent unwanted cloudiness during storage of the agents according to the invention and/or so that the intended transformation into a cream, a lotion or a gel only takes place on contact with water, it is advantageous if the hair treatment agents according to the invention are essentially free of added water.

“Essentially free” means that the hair treatment compositions according to the invention (based on their total weight) preferably have a maximum content of 15% by weight, more preferably 12.5% by weight, particularly preferably 10% by weight and very particularly preferably 7.5% by weight of free water. Particularly preferably, no free water is added to the hair treatment agents according to the invention.

The agents according to the invention can nevertheless contain a small proportion of water within the limits mentioned above; for example in the event that water is a component of mixtures of active substances which can be added to the hair treatment agents according to the invention.

In addition to the active substances described above, the hair treatment compositions according to the invention can contain other ingredients. The group of these other ingredients includes in particular the cosmetically active ingredients, auxiliaries and additives.

A first group of optional ingredients are the so-called fats or oils e), which have already been described earlier in this application.

Other suitable active substances, auxiliaries and additives are, in particular, additional care substances. The hair treatment agent can contain, for example, at least one protein hydrolyzate and/or one of the derivatives thereof as a care substance.
