My sister is wondering about how to preserve beauty products, including
creams for your face, hands and babies bottoms, so that they can last more
than a couple of weeks. Thanks.
Good question, especially these days, given that paraben preservatives commonly found in personal care products are hormone disrupters and it is in our interest to find healthy alternatives!
I think that the easiest way to preserve kitchen cosmetics is to use
grapefruit seed extract, easily found in health food stores and used by some
personal care product manufacturers such as Aubrey Organics. This choice
would be expensive for producing gallons of creams and lotions, but for
small batches it is by far the most convenient. Use 6 drops per ounce of
cream of oil, or 1/3 teaspoon per cup. You can also use antiseptic essential
oils such as rose, clove, rosemary or lavender. Only use small amounts. Per
ounce of cream or oil, use 3 drops or less (eye area), 5 drops or less
(face), or 25 drops or less (body).
