Stabilization of cosmetic compositions

A method of moisture stabilizing a cosmetic product or personal care product against effects of exposure to humidity comprising the steps of:

• h) providing a highly refined cellulose fiber;
• i) combining the highly refined cellulose fiber with a liquid carrier that is either hydrophilic or hydrophobic to form a first additive composition;
• j) combining the first additive composition formed in step b) with at least one ingredient selected from the class of polymers, waxes and oils to form a cosmetic product or personal care product having a final composition;
• and
• k) storing the cosmetic product or personal care product.

A method of oil-migration stabilizing a cosmetic product or personal care product against effects of internal migration or blushing of oil:

• e) providing a highly refined cellulose fiber;
• f) combining the highly refined cellulose fiber with a liquid carrier that is either hydrophilic or hydrophobic to form a first additive composition;
• g) combining the first additive composition formed in step b) with at least one ingredient selected from the class of polymers, waxes and oils to form a cosmetic product or personal care product having a final composition with at least 3% by total weight of oil;
• and
• h) storing the cosmetic product or personal care product.
