Paraffinum liquidum is an emollient that has water-resistant properties making it an ideal choice for a variety of cosmetic and skin care products. It works well on all skin types offering smoothness and softness.
WebThe degree to which a mineral stands out against its background is a function of the difference between the respective refractive indices of mineral and background. In a colorless immersion oil of the same refractive index, a colorless mineral grain is hardly visible in plane-polarized light because it has no relief.
