These Tea Tree Spheres are dry, spherical beads mainly consisting of Mannitol, Lactose or Xylitol and micro-crystalline Cellulose. They may contain pigments and up to 5% of water-insoluble active ingredients (Tea Tree Oil). They are not soluble in water but they soften in final products containing water and they can be easily rubbed into skin or hair with no residue.
Product Benefits of Tea Tree Spheres
- Spheres are optically striking beads which soften with water but retain their shape.
- When rubbed onto skin or hair, they break easily, releasing the active TeaTree content. They leave no shell nor residue.
- do not contain preservatives.
- are stable over a wide pH range, 3.0 to 10.0
- are stable to light and a wide range of temperatures.
- are extremely safe and non toxic.
- these Tea Tree spheres provide an optical visualization of the active Tea Tree Oil
- Hard and solid in bulk (easy to process, no water, no preservatives)
Suitable Application Areas
- Clear gels (e.g shower gels, shampoo, handwash)
- Melt and Pour Soap
Typical use level
Tea Tree spheres can be used in many types of cosmetic products, both clear formulations (gels, shampoos, liquid soaps, antiperspirants, deodorants) and emulsions (cleansers, creams and lotions, hair conditioners).
Different coloured spheres can be used in the same product for an enhanced visual effect. Formulas should have sufficient yield values to keep the beads suspended, usually with the aid of common associative thickeners or in high viscosity emulsions In very few cases, certain surfactants, solubilisers or emulsifiers may show incompatibilities with active compounds of the spheres. Spheres can take several hours to soften in a formula. They should be added at the end of the manufacturing process with low shear mixing, but can be safely pumped (using a membrane, peristaltic or piston pump) and filled without breakage.
Tea Tree Spheres soften best in formulas with at least 30% available water content. In low water-content formulas, or in formulas where other ingredients (surfactants, polymeric thickeners, etc.) tie up most of the water, the spheres can be pre-soaked in water to soften before adding to the batch.
