• Ground nut shells and fruit stones from almond, coconut, walnut, apricot, avocado, olive or peach. These are rough and are suitable for hard areas of the skin such as feet and elbows.
• Plant seeds from blue poppy, evening primrose, rose hip or kiwi look natural and are used in shower gels.
• Corn cob granules exhibit mild abrasive action. Used in face and body scrubs.
• Adzuki beans are coarse milled Japanese washing beans; good for face and body washes.
• Ground luffa is used in hard skin removers.
• Jojoba wax prills are smooth, round beads with low particle size distribution for facial cleansers.
• Jojoba wax beads are irregular granules that come in various sizes and a variety of colors.They have visual appeal in shower gels.
• Microwax meal beads are jojoba seed powders incorporated in a microcrystalline wax. They appear as a beige color when used in shower gels and body cleansers.
• Hydrogenated vegetable oils such as palm and soybean have a “roll-up” action that visually collects grime. Ideal in emulsion type cleansers.
• Ground egg shells and pumice are fine ground powders. Pumice from volcanic lava contains about 71% silica (SiO2), 13% alumina (Al2O3) and small amounts of iron, potassium, calcium and other minerals.
Of course, whatever nature makes, chemists try to improve, or at least replicate. Some synthetic exfoliants include polyethylene spheres and granules. Polyethylene spheres are smooth, round beads with low particle size distribution, which are available in different meshes and colors and can be used in shower gels and body cleansers.
Polyethylene granules and styrene granules are both available in different colors and mesh sizes for use in shower gels and body cleansers. The following scrub from Aloecorp shows the use of polyethylene beads.

Chemical exfoliants are usually alpha hydroxyl acids (AHA) such as glycolic or lactic acids.They can also be a mixture of citric fruit acids as the formula below by Centerchem illustrates.
Magnesium aluminum silicate1.00
Glyceryl stearate (and)1.00
C12-15 alkyl benzoate4.00
Pronalen fruit acid AHA-355.00
Procedure: Disperse the silicate and gum in water and heat to 75°C. Add rest of A. Heat B to 75°C and add to A. Add TEA and mix for 30 minutes. Cool to 40°C and add last two ingredients. Mix and cool to 35°C.
