Function

ANTIFOAMING: Suppressing foam during manufacturing or reducing the tendency of finished products to generate foam.
SKIN CONDITIONING - EMOLLIENT: Acting as lubricants on the skin surface providing the skin with a soft and smooth appearance.
HAIR CONDITIONING: Enhancing the appearance and feel of hair. Leaving the hair easy to comb, supple, soft and shiny and/or imparting volume, lightness, gloss, texture, etc.
DISPERSING NON-SURFACTANT: Facilitating the dispersion of solids in liquids. They function primarily by coating the solid through the process of adsorption, thus changing the surface characteristic of the suspended solid.
SLIP MODIFIER: Enhancing the flow properties of other ingredients without reacting chemically with them.
SURFACE MODIFIER: Applied to other cosmetic components to make them more hydrophilic or hydrophobic, or to modify their physical/chemical properties.
