Abstract

A cosmetic oil-in-water cleaning emulsion is described, comprising a) at least one anionic carboxylate surfactant, b) at least one C16-30 fatty alcohol, c) at least one vegetable butter, d) at least one vegetable oil and e) water in a proportion by weight of at least 70% by weight based on the total weight of the oil-in-water cleaning emulsion.

Description

The invention is in the field of cosmetics and relates to O / W cleaning emulsions, comprising anionic carboxylate surfactants, fatty alcohols and vegetable oils and butters. The invention also relates to a method for producing cosmetic O / W cleaning emulsions.

Cosmetic cleaning agents such as liquid soaps, shampoos, shower baths, foam baths, shower and / or washing gels have been known for a long time and are regularly adapted to the changing needs of consumers.
In the past, so-called 2-in-1 preparations were developed which allow the human body to be cleaned and cared for in one application step. This results in less packaging waste and reduces the time and / or costs involved in personal cleaning and / or care.
The problem with the production of such preparations is the incorporation of water-insoluble care components necessary for the care, because the dispersion and stabilization of the care components in conventional cleaning agents can often only be achieved by incorporating additional crystalline or polymeric components.

There are also shower lotions available on the market that can be used directly in the shower after the body has been cleansed with a conventional cleansing composition. It is used by applying it to the skin and then rinsing it off with water. Such shower lotions do not contain conventional surfactants, which is why the rinsing step with water takes a long time and requires large amounts of water. In addition, shower lotions leave a slippery film in the shower tray, which in turn has to be removed with water.

There is a need for improved 2-in-1 preparations that use less water when used.

In DE 102015219021 cleaning emulsions have been disclosed which comprise an O / W emulsion phase and a surfactant phase. The cleansing emulsions are intended for use in the shower, ensure excellent cleaning and care of the skin and can be rinsed off quickly and easily with water.

However, the desire of consumers for more natural products (according to the COSMOS standard) that can be produced and used more sustainably remains. In particular, sulfate-free products are increasingly preferred.

Dispensing with sulfate surfactants has so far led to the aforementioned problems with commercially available shower lotions, because sulfate surfactants have previously been necessary for sufficient solubilization and thus the rinsability of water-insoluble care components.

• - einfach und energieeffizient herstellbar sind,
• - überwiegend aus natürlichen Quellen erhältliche Inhaltsstoffe umfassen,
• - bei der Anwendung einen geringeren Wasserverbrauch verursachen,
• - dem COSMOS-Standard entsprechen,
• - keine Sulfattenside enthalten und
• - eine hohe Pflegeleistung (insbesondere eine gegenüber vergleichbaren Produkten verbesserte Hautaustrocknung) aufweisen.

The object of the present invention was to provide 2-in-1 cleaning and care preparations which do not have or cause the problems mentioned.
The aim was in particular to provide 2in1 cleaning and care preparations that

• - can be produced easily and energy-efficiently,
• - contain ingredients that are predominantly available from natural sources,
• - cause less water consumption during application,
• - conform to the COSMOS standard,
• - do not contain sulphate surfactants and
• - have a high level of care performance (in particular, skin dehydration is better than that of comparable products).

It has surprisingly been found that the aforementioned objects can be achieved by combining specific carboxylate surfactants and water with specific oil and fatty substances to form an oil-in-water cleaning emulsion.

Such available O / W cleaning emulsions (so-called shower creams) have the advantages of a mild, sulfate-free shower gel and a caring body lotion.

It is sufficient to apply the Shower Creams on wet skin while showering and then rinse off. Compared to existing market products, this saves a lot of water, because the surfactants contained make it easier and faster to rinse off the shower creams and the shower tray is also soiled much less or not at all by product residues.

The raw materials used correspond to the Cosmos regulations, i.e. correspond to the desire of consumers for natural products (99% natural ingredients according to Cosmos). A new method of manufacturing the shower creams, adapted to natural ingredients, also allows the incorporation of sensitive components such as cold-pressed vegetable oils without adversely affecting the stability of the products.

Another advantage is that no additives that consumers or NGOs have recently seen as critical (such as solid or liquid microplastic components) need to be used in the shower creams for stabilization or viscosity adjustment.

The oil-in-water cleansing emulsions can be spread very easily on the skin while showering and rinsed off quickly and thoroughly with water without the need to add sulfate surfactants.
It is also not necessary to add synthetic stabilizing products to the cleaning products. In particular, the use of alkoxylated compounds is not necessary.

A preferred embodiment is accordingly characterized in that the oil-in-water cleaning emulsions according to the invention are essentially free of anionic sulfate surfactants.

“Natural origin” is understood to mean that the abrasive does not have to be produced synthetically, but that naturally occurring materials are used, which may be crushed beforehand. Organic and inorganic materials can be used as abrasives.

The at least one abrasive of natural origin can be used in the oil-in-water cleaning emulsions according to the invention preferably in a weight proportion of 0.01 to 5% by weight of the total weight of the oil-in-water cleaning emulsions. Preference is given to proportions by weight of 0.05 to 3% by weight, particularly preferably 0.1 to 2% by weight and in particular 0.15 to 1% by weight.

Examples of organic abrasives of natural origin are (crystalline) cellulose; Vegetable waxes such as jojoba wax; crushed and / or ground parts of plants such as shells, seeds, kernels and / or nuts, such as peach kernels, apricot kernels, walnut kernels, orange kernels, bitter orange kernels, grape kernels, lychee kernels, almond kernels, cherry kernels, cranberry seeds, lotus seeds, macadamia nuts and other nuts, coconuts; Bran such as almond bran, wheat bran; Flours such as oatmeal, sawdust (wood flour), nutshell flour; Powders such as ginger powder, green tea powder, hibiscus seed powder, star anise powder; crushed and / or ground algae; Polylactic acid.
Examples of inorganic abrasives of natural origin are clay, talc powder, zeolites, rhyolite, sand, sea sand, powdered pumice stone, chalk, powdered shell limestone, powdered marble, coal and / or lava ash.

The absolute particle sizes of the organic and / or inorganic abrasives of natural origin can preferably be in the range from 40 to 500 μm.
The use of smaller particle sizes leads to an overall poorer effect of the cleaning products according to the invention, the abrasives of particularly small particle sizes - especially in the case of the Use on large-pored skin - can sometimes lead to clogging of the skin pores. Inflamed skin pores can result in undesirable inflammatory reactions.
The use of larger particle sizes also leads to a poorer effect of the cleaning products according to the invention, since the abrasive effect of large particles is too strong and can lead to irritation and / or damage to the skin.
Particle sizes of the abrasives in the range from 40 to 400 μm, more preferably from 50 to 300 μm, particularly preferably from 60 to 250 μm and in particular from 70 to 200 μm are therefore particularly preferred.

In a preferred embodiment, the cleaning products according to the invention contain one or more abrasives of natural origin selected from plant waxes, crushed and / or ground plant parts such as shells, kernels and / or nuts, bran, celluloses, minerals such as sand and / or lava ash .
