Definitions
- In-house enzymes in the sense of the present document are enzymes which are present on or near the surface of the skin.
- Such enzymes can be; Hydrolases, such as proteases, esterases, lipases, phosphatases, sulfatases and transglutaminases, but especially proteases such as the stratum comeum tryptic enzyme.
- Hydrolases such as proteases, esterases, lipases, phosphatases, sulfatases and transglutaminases, but especially proteases such as the stratum comeum tryptic enzyme.
- the most important stratum comeum enzymes known from the literature are shown in Tables 1 and 2 and below.
- Ammonia lyases play an important role in filaggrin degradation (Kuroda et al., 1979). Just like transglutaminases (Polakowska et al., 1991), which are essential for the formation of the 'Cornified Envelope'. Phosphatases are the hydrolases with the highest total activity in the stratum corneum. Influence of enzymes on desquamation (see Schepky et al., 2004, Influence of cleansing on stratum comeum tryptic enzyme (S CTE) in human volonteers, Int. Journal of Cosmetic Science, 26, 245 -253)
- SCCE stratum comeum chymotryptic enzyme
- SCTE stratum comeum tryptic enzyme
- Skin washing products contain anionic surfactants, eg sodium dodecyl sulphate (SDS) or sodium lauryl ether sulphate (SLES).
- anionic surfactants eg sodium dodecyl sulphate (SDS) or sodium lauryl ether sulphate (SLES).
- SDS sodium dodecyl sulphate
- SLES sodium lauryl ether sulphate
- Such anionic surfactants are strong because of their Binding to globular proteins on and into the skin by electrostatic interaction of their charged group with the oppositely charged amino acid group of the proteins is well known.
- the hydrophobic alkyl chain of the molecules of the surfactant also act on the non-polar zone of the globular proteins.
- surfactants induce conformational changes in the protein molecules that normally lead to the loss of biological, ie enzymatic, activity.
- Damage to the skin's own enzymes in the sense of the present document means any form of inactivation of these enzymes by denaturation, inhibition or chemical degradation. If enzymes come into contact with surfactants, denaturation very often occurs. Prottey et al., 1984 quantified the effect of surfactants on the acidic phosphatase of the stratum corneum (obtained by tape stripping) by measuring the phosphatase activity. A reduction in the enzyme activity by denaturing the enzyme was found. Based on further data, the surfactant sensitivity of most surface-active skin enzymes can be assumed.
- enzyme protection in the sense of the present document means reduced damage / impairment of the skin enzymes described.
- the known products contain, for example, mixtures of lauryl ether sulfate and alk ylamidopropyl betaine. By using such products there is a partial denaturation of the skin's own enzymes and thus damage to the skin, since these enzymes play an important role physiologically.
- the enzyme protection can be quantified as follows: First, an ex vivo determination of the effect of surfactants on trypsin activity in the human epidermis is carried out. Subjects wash themselves under supervision several times in 3 days with different products or water in different areas. The upper stratum com eum is extracted 24 hours later. The stratum comeum tryptic enzyme (SCTE) activity is measured in the extract. In parallel, the protein concentration of the extracts is determined in order to maintain the specific trypsin activity (correction of different extraction of the areas).
- SCTE stratum comeum tryptic enzyme
- EP 0 691 127 discloses mild shower products with anionic surfactants and MIPA laureth sulfate and oils.
- EP 0691127 B1 disclose the use of anhydrous oils in surfactant cleaning preparations to reduce the binding of certain surfactants to the skin surface.
- the use of oils reduces the damage to the skin enzymes caused by anionic surfactants and achieves effective enzyme protection. The cause is a reduced adsorption of the surfactants on the skin. This enables enzymes to better fulfill their tasks in the skin.
- the surfactant is a anionic surfactant, preferably a sulfate surfactant, particularly preferably MIPA-laureth sulfate.
- a buffer system consisting of citric acid and citrate ions is additionally contained and the pH value of the preparation is adjusted to the value 4 to 7.
- the concentration of anionic surfactants is 5 to 15% by weight.
- Oils are characterized in that they reduce the adsorption of the respective anionic surfactant. This enables the enzymes to better fulfill their essential functions in the skin. This effect can be increased by setting the product to a skin-neutral value with citric acid buffer.
- Preparations according to the invention can furthermore contain surfactants.
- Particularly preferred surfactants are nonionic surfactants. The following are considered as nonionic surfactants:
- Alkanolamides such as Cocamide MEA / DEA / MIPA
- Esters which are formed by esterification of carboxylic acids with ethylene oxide, glycerol, sor bitane or other alcohols, ethers, for example ethoxylated alcohols, ethoxylated esters, ethoxylated glycerol esters
- Alkyl polyglycosides such as lauryl glucoside, decyl glycoside and cocoglycoside.
- Fatty alcohols such as cetyl alcohol can advantageously be present. Furthermore, all straight-chain and branched fatty alcohols with 8 -22 C atoms
- Conditioning aids may also be present in the cosmetic cleaning agents, for example in amounts of 0.001 to 10% by weight, based on the total weight of the preparations.
- Preservatives approved in food technology which are listed below with their E number, can advantageously be used according to the invention.
- test areas were treated three times a day three times a day with 1 mL washing product or a tap water control for 45 s. After the treatment, the test area was rinsed with tap water for 30 s and dried with a disposable paper towel. The areas were treated three times on the 1st and 2nd day (morning, noon and afternoon), and on the 3rd day they were treated twice (morning and noon). Up to three washing products were tested against each other and against water.
- the protein content was determined using the ninhydrin method after alkaline hydrolysis.
- the corneocyte solutions were evaporated to dryness and the proteins were hydrolyzed for 5 h at 150 ° C. with 2 mL sodium hydroxide solution (6M).
- the solution was neutralized with 2 mL hydrochloric acid (6M) and 1 mL sodium propionic acid buffer (3.35 M, pH 5.5) was added. Then 50 ⁇ L of the lysate were mixed with 450 ⁇ L bidest.
