Definitions
- the present invention describes a cosmetic cleansing preparation which is intended in particular for preparing for shaving, but also for facial cleansing.
- the preparation contains a surfactant system that includes a selection of certain surfactants.
- the preparation is free of polymeric thickeners and sulfate surfactants.
- Cleansing the skin and skin appendages is now part of everyday life in many cultures, almost comparable to eating and drinking. Cleansing primarily involves removing dirt, which often lies on the surface of the skin in the form of a film, from the surface of the skin.
- the dirt film consists of solid or liquid components that have come onto the skin from outside.
- the dirt film also includes excess skin lipids and dead body cells.
- Surface-active ingredients in the cleaning compositions remove the components of the dirt film from the skin during the rinsing process and enter the washing liquor.
- surface lipids of the skin for example barrier lipids, can also be dissolved in the cleaning preparations by the surface-active substances and removed during the rinsing process. An attempt is therefore made to mitigate these phenomena by selecting suitable surfactants and/or incorporating moisturizing components.
- Preparation for shaving is a procedure, especially when shaving wetly, that results in the (beard) hair being softened so that the effort required during shaving is reduced. This reduces the pulling on the hair shaft ("pulling").
- the softening of the (beard) hair is achieved through water absorption.
- the sebum layer of the hair must be removed so that the water absorption can take place sufficiently well and quickly.
- Consumers are increasingly demanding products, including cleaning products, that do not harm the environment. There are two aspects to consider here; On the one hand, such products should consist largely or entirely of natural or nature-based ingredients and, on the other hand, the ingredients and the entire product should be readily biodegradable.
- natural cosmetic ingredients can be collectively described as substances that are available from plants, animals, minerals or microorganisms, including such substances , which are obtained from the sources mentioned through physical processes, fermentation processes (only those fermentation processes that also occur in nature and which lead to products that are also created in nature) and other manufacturing methods without intended chemical modification.
- the microorganisms may only be those be that have not been genetically modified.
- nature-based substances are compounds that are derived from natural starting materials or are produced starting from natural starting materials.
- BCI Biorenewable Carbon Index
- biodegradability describes the process of breaking down organic compounds by living organisms, especially saprobionts.
- inorganic substances are created, such as CO2, O2 and ammonia; Compounds that are reused by plants and microorganisms to build organic compounds.
- Organic chemical compounds that are easily biodegradable are classified according to OECD 301, and for cosmetic compositions they are usually classified according to OECD 301 B. These substances or compositions can be broken down quickly and completely.
- Organic chemical compounds classified according to OECD 302 are restricted but fundamentally biodegradable.
- cleaning preparations should have a suitable consistency.
- the preparations should be easy to remove from the packaging; On the other hand, they must not be too thin, as good distribution on the skin and remaining on the skin during the washing process and preparation for shaving is essential in order to achieve a cleansing effect and a comparatively pleasant shave.
- the cleaning preparations must have a certain viscosity in order to meet the criteria mentioned. This viscosity is usually described by the viscosity; for shower baths, for example, a viscosity of 3000 to 10,000 mPa-s is disclosed (cosmetics; Umbach, 1995; 1 12-1 13).
- polymeric thickeners are often incorporated into cleaning preparations.
- These polymeric thickeners are hydrocolloids. These are macromolecules that have a largely linear shape and have intermolecular interaction forces that enable secondary and main valence bonds between the individual molecules and thus the formation of a network-like structure. They are partially water-soluble natural or synthetic polymers that form gels or viscous solutions in aqueous systems. They increase the viscosity of the water by either binding water molecules (hydration) or absorbing and enveloping the water in their interwoven macromolecules, while at the same time restricting the mobility of the water.
- Such water-soluble or water-swellable polymers represent a large group of chemically very different natural and synthetic polymers, the common feature of which is their solubility or swellability in water or aqueous media.
- the prerequisite for this is that these polymers have a sufficient number of hydrophilic groups for water solubility and are not too strongly cross-linked.
- the hydrophilic groups can be nonionic, anionic or cationic in nature.
- the group of cosmetically and dermatologically relevant hydrocolloids can be divided into:
- the thickeners can therefore be of synthetic origin and then have no equivalent in nature. Therefore, there are no natural degradation pathways and such polymers are generally difficult to biodegrade.
- Sulfate surfactants are known to have a certain irritating potential for the skin and mucous membranes.
- the task was therefore to provide preparations for cleaning the facial skin and preparing for shaving, which do not contain sulfate surfactants or polymeric thickeners, but nevertheless achieve good shaving preparation and cleaning for the skin and are characterized by sufficient mildness.
- the preparations should have a consistency that allows easy removal from the packaging, but should not be too thin, so that distribution and retention on the skin is ensured during the cleaning process.
- Cocamidopropyl betaine is biodegradable and the BCI is around 63.
