If a product contains water (including hydrosols, floral water and aloe vera juice, all of which contain water), a preservative is essential to help prevent microbes growing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Anhydrous (water-free) products generally don\u2019t require preservatives as they are not prone to microbial contamination. This includes products like lip balms and anhydrous whipped body butters. The exception here is an anhydrous product that might come into contact with water (eg a body scrub or a cleansing balm applied with wet fingers). With these types of products you either need to be very careful not to introduce water to the product during use, or you should include a preservative. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">You will need to use a <strong>broad-spectrum preservative<\/strong>, which means it is effective against bacteria, mold and yeast.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s important to follow the manufacturer\u2019s instructions regarding the amount of preservative to use; too much or too little could be potentially hazardous.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The only way to know that your preservative is working effectively is to have a microbiological challenge test carried out by a lab. This is recommended (and in some countries compulsory) if you are selling your products.<\/span><\/p>\n<p class=\"p2\"><span style=\"font-weight: 400;\">Vitamin E, rosemary extract and grapefruit seed extract are <\/span><b>not <\/b><span style=\"font-weight: 400;\">preservatives.
