Industrial skin cleansing products are part of the company's three-stage skin protection concept. In industrial practice today almost only pure (without soaps), synthetic surfactant mixtures (synthetic detergents = syndets) are represented in the pH skin neutral range. In addition to the washing raw materials, skin-friendly rubbing agents such as wood flour or plastics are also used in these. As an alternative to plastics, biodegradable materials such as nut shell flour, olive kernel flour and corncob flour ("bio grating bodies") are used. This enables a graduated and gentle skin cleansing. For example, a skin cleansing agent against coarse soiling consists of descending proportions of water, surfactants, rubbing agents, solvents, consistency agents, refatting agents, colours, preservatives and perfume.
Selection and composition of skin cleansing agents basically depend on the type of soiling (simple, coarse, special), whereas a corresponding step-by-step plan has to be observed depending on the degree of soiling. Strictly to be avoided are cleansing procedures with technical cleansers, brushes or pumice stone which are highly straining for the skin.
Surfactants have the task to emulsify or disperse water-insoluble soiling. They alone, however, do not guarantee a thorough cleaning of the skin in case of coarse soiling. Rubbing agents (abrasives) must be used for mechanical support.
Every cleaning of the skin also removes lipid substances. In case of normal stress the skin is able to replace these substances relatively quickly. In the industrial sector it is useful to support this regeneration process. If the replenishment of moisture and lipid substances is mainly left to the skin care products, the additional application of re-fattening agents directly in the skin cleansers is another possibility to support the regeneration process. For this purpose e.g. fatty acid monoglycerides, lanolin derivatives, ethoxylated triglycerides, polyol fatty acid esters and others may be considered. However, the use of skin care products should not be avoided here either.
The use of organic solvents (dibasic esters, paraffins, isoparaffins) is limited to special products as they always have a degreasing effect on the skin.
Auxiliary agents are consistency enhancers (thickeners), colorants, preservatives and perfumes. The auxiliary substances adapt the properties of the already usable cleansing product to special requirements like storage stability, acceptance by the user or dosage.
With regard to the pH value as a physical quality parameter, most manufacturers are currently aiming at a pH range of 5.5 to 7 for products containing surfactants.
When cleaning the skin, the principle always applies that it should be as gentle as possible on the skin, but at the same time it should also effectively remove soiling.
Recommended procedure for washing hands:
- Do not wash hands out of habit
- Remove coarse soiling first with paper towels or a clean cloth
- Apply hand cleanser/pH-skin neutral syndet without water and rub in thoroughly
- Dissolve dirt and wash hands with a little lukewarm water
- Rinse hands thoroughly with plenty of lukewarm water
- Dry hands carefully with soft disposable towels if possible.
