Definitions
- the invention relates to an agent for protecting the skin from aqueous solutions, comprising 0.1 to 50% by weight of viscous paraffinol, 0.1 to 40% by weight of petrolatum, 0.1 to 10% by weight of camauba wax, 1 to 5% by weight of at least one additional wax, 0.1 to 30% by weight of low-viscosity paraffinol and / or silicone oil and 0 to 40% by weight of at least one additional macro- and / or microcrystalline wax.
- the natural lipophilic protective layer of the skin normally protects it from the penetration of aqueous pollutants and from drying out. Due to frequent contact with water, even by frequent hand washing, the natural moisturizing substances are lost and the skin dries out. The constant contact with water causes the skin to swell, making it even more permeable to damaging environmental influences. Pollutants dissolved in aqueous solutions can penetrate the body through the skin almost unhindered.
- the hands are often exposed to irritants when working in the laboratory, handicraft, clinics or during construction.
- hands are particularly at risk when coming into contact with water-miscible agents (e.g. dishwashing detergents, disinfectants, bleaching agents, water-mixed cooling lubricants, mixtures of lime, fertilizer, glues, resins or cement with water, dye solutions, acids, salt solutions).
- water-miscible agents e.g. dishwashing detergents, disinfectants, bleaching agents, water-mixed cooling lubricants, mixtures of lime, fertilizer, glues, resins or cement with water, dye solutions, acids, salt solutions.
- alkaline substances e.g. alkalis or permanent waving agents
- alkaline substances can overstress the skin's ability to neutralize alkalis. Therefore, it is advisable to: Contact with aqueous solutions that may contain irritants, lotion the appropriate skin areas with suitable skin protection ointments.
- water-in-oil (w / o) emulsions such as e.g. high-fat creams are used, which often only insufficiently protect the skin.
- w / o emulsions water-in-oil (w / o) emulsions, which often only insufficiently protect the skin.
- Another disadvantage of these creams is that they do not stick to the skin for a long time, but can be rubbed off or washed off very quickly. Since they usually contain large amounts of emulsifiers, they are too permeable when heavily used by aqueous solutions.
- the object of the invention is therefore to provide an agent which better protects the skin from the action of aqueous solutions and any irritants contained therein and, with simultaneous good application behavior, adheres longer to the skin and cannot be easily rubbed off.
- an agent comprising 0.1 to 50% by weight viscous paraffinol, 0.1 to 40% by weight petrolatum, 0.1 to 10% by weight camauba wax, 0.1 to 5% by weight .-% of at least one additional wax, 0.1 to 30% by weight of low-viscosity paraffinol and / or silicone oil and 0 to 40% by weight of at least one additional macro and / or microcrystalline wax.

- ⁇ TEWL TEWL (after the application) - TEWL (before the application).
- the measurement was carried out with a TEWA meter (TM 210, Courage and Khazaka, Cologne) at the application sites on the forearm before the application of the substances and at the end of the test. An air-conditioning period of at least 10 minutes was observed before each measurement. For each area of measurement, TEWL values and the reddening of the skin are recorded.
- various commercially available skin protection products are also tested (for composition, see Table 2). The following pollutant solutions (untreated / treated) are applied in succession for 5 minutes each:
- the skin protection formulation 1 further shows a much smaller transepidermal water loss compared to the unprotected skin when treated with the commercial bleaching agent, i.e. the damage to the skin by the irritants is significantly less when the skin protection formulation according to the invention is used (Table 4).
