Voorbeeldzinnen

1. Helps eliminate the dead cells of the stratum corneum. MASKING
2. Multiple layers of viable epithelial cells (basal layer, stratum spinosum, stratum granulosum) should be present under a functional stratum corneum.
3. Enhances the solubility of substance which is only slightly soluble in water. KERATOLYTIC Helps eliminate the dead cells of the stratum corneum. MASKING
4. Histological examination of the reconstructed skin/epidermis should be performed by appropriately qualified personnel demonstrating human skin/epidermis-like structure (including multilayered stratum corneum).
5. It consists of organised basal, spinous and granular layers, and a multilayered stratum corneum containing intercellular lamellar lipid layers arranged in patterns analogous to those found in vivo. The principle of the reconstructed human epidermis model test is based on the premise that irritant substances are able to penetrate the stratum corneum by diffusion and are cytotoxic to the cells in the underlying layers.
6. The containment properties of the model should prevent the passage of material around the stratum corneum to the viable tissue, which would lead to poor modelling of skin exposure.
7. The stratum corneum and its lipid composition should be sufficient to resist the rapid penetration of cytotoxic marker substances, e.g. SDS or Triton X-100, as estimated by IC50 or ET50.
8. The principle of the reconstructed human epidermis model test is based on the premise that irritant substances are able to penetrate the stratum corneum by diffusion and are cytotoxic to the cells in the underlying layers.
9. Stratum corneum should be multilayered containing the essential lipid profile to produce a functional barrier with robustness to resist rapid penetration of cytotoxic marker substances, e.g. sodium dodecyl sulphate (SDS) or Triton X-100.
10. A dye-binding step is incorporated into the test procedure for confirmation testing of positive results in the TER including values around 5 kΩ. The dye-binding step determines if the increase in ionic permeability is due to physical destruction of the stratum corneum.
11. The term “Ceramide” as part of an INCI name will be assigned to those classes and structures of natural lipids derived from skin as reported by Wertz P.W., Miethke M.C., Long S.A., Strauss J.M. and Downing D.T. in “The composition of ceramides from human stratum corneum and from comedones”, The Journal of Investigative Dermatology, 84, 410-412 (1985).
12. HAIR WAVING OR STRAIGHTENING Modifies the chemical structure of the hair, allowing it to be set in the style required. HUMECTANT Holds and retains moisture. HYDROTROPE Enhances the solubility of substance which is only slightly soluble in water. KERATOLYTIC Helps eliminate the dead cells of the stratum corneum. MASKING Reduces or inhibits the basic odour or taste of the product. MOISTURISING Increases the water content of the skin and helps keep it soft and smooth. NAIL CONDITIONING Improves the cosmetic characteristics of the nail. OPACIFYING Reduces transparency or translucency of cosmetics. ORAL CARE Provides cosmetic effects to the oral cavity, e.g. cleansing, deodorising, protecting. OXIDISING
13. FOAM BOOSTING Improves the quality of the foam produced by a system by increasing one or more of the following properties: volume, texture and/or stability. GEL FORMING Gives the consistency of a gel (a semi-solid preparation with some elasticity) to a liquid preparation. HAIR CONDITIONING Leaves the hair easy to comb, supple, soft and shiny and/or imparts volume, lightness, gloss, etc. HAIR DYEING Colours hair. HAIR FIXING Permits physical control of hairstyle. HAIR WAVING OR STRAIGHTENING Modifies the chemical structure of the hair, allowing it to be set in the style required. HUMECTANT Holds and retains moisture. HYDROTROPE Enhances the solubility of substance which is only slightly soluble in water. KERATOLYTIC Helps eliminate the dead cells of the stratum corneum. MASKING Reduces or inhibits the basic odour or taste of the product. MOISTURISING Increases the water content of the skin and helps keep it soft and smooth. NAIL CONDITIONING Improves the cosmetic characteristics of the nail. OPACIFYING Reduces transparency or translucency of cosmetics. ORAL CARE Provides cosmetic effects to the oral cavity, e.g. cleansing, deodorising, protecting. OXIDISING Changes the chemical nature of another substance by adding oxygen or removing hydrogen. PEARLESCENT Imparts a nacreous appearance to cosmetics. PLASTICISER Softens and makes supple another substance that otherwise could not be easily deformed, spread or worked out. PRESERVATIVE Inhibits primarily the development of micro-organisms in cosmetics.
