  • How do I store alginate powder?

    Always store alginate cool and dry. When opening a bag, pour the alginate in an airtight container. The Cavex alginate container combines proper storage with ease of use.

  • After mixing, the alginate is running or too thin. What happened?

    Most likely too much water was used, which results in a thin and running mixture. Check packaging for right proportions. Make sure the right measuring tools are used. Cavex alginates have their own specific water cups and alginate spoons. They are easy to recognize as they all have the Cavex logo.

  • Setting time is too quick or too slow. What might cause this?

    Temperature directly influences the setting time of alginates. Rise in temperature of 1 °C will reduce the setting with approximately 5 seconds and vice versa. By using water at room temperature the setting time will be the same at all times. In tropical environments, room temperature might be too high. It is then advised to use colder water. Water containing a lot of Calcium will reduce the setting time. Distilled water will slow down the setting.

  • The alginate mixture contains air bubbles. What happened?

    The alginate was not mixed properly. For best mixing by hand, use a flexible cup and a firm spatula.

  • Does disinfection influence the stability of an alginate impression?

    No, as long as the impression is not submerged for too long (i.e. Cavex ImpreSafe). Cavex advises against the use of alcohol-based disinfectants. These disinfectants will too quickly withdraw water from the impression, thus resulting in deformation.

  • During disinfection the solution shows a haze. Is this harmful?

    No, this is normal. When submerging an alginate impression in a water-based solution the impression will dissolve a little. The longer the impression is submerged, the more the impression will dissolve. As long as the impression is not left submerged for too long, dissolving will do no harm to the accuracy.

  • How to handle an impression after removing it from the mouth?

    Immediately after removing the impression from the mouth, rinse under running tap water to remove saliva and other residues. Disinfect the impression as normal. See earlier questions for more information and recommendations regarding disinfection. After disinfection rinse impression under running tap water. Remove excessive water from impression by giving it a light tap or shake. Do not wipe or blow dry! Place impression in an airtight bag and/or container. Never include a piece of moist paper, cotton or water! This will cause swelling of the impression, resulting in distortions. Keep impressions at room temperature during the entire transport. Keep away from direct sunlight.

  • Does Cavex alginate contain latex, lactose, gluten or balsam of Peru?

    No. Cavex alginate does not contain latex, lactose, gluten or balsam of Peru.
    Hypersensitivity for gluten, coeliakie, is a food allergy in which the human body does not bear gluten. Gluten are proteins that are found in wheat, oat, rye, barley, spelt and kamut. When those who suffer from coeliakie eat gluten, they will show symptoms like fatigue, stomachache, loss of weight and apathy.

  • My patient is allergic to alginate. Can you give me the ingredients of your product?

    No, all ingredients of our alginates are confidential. However, if the patient can state his allergy, we can either confirm or deny if the allergic reaction is caused by any of our ingredients. If needed, we are willing to discuss the composition of the alginate with the patient’s dermatologist. The most common allergic reaction to alginates is caused by flavorings (peppermint) or coloring agents.
