To prevent unpleasant underarm odour, deodorants are essential products in most people\u2019s daily hygiene routine. Consumers are becoming more selective when choosing their deodorants and are critical of conventional deodorising ingredients. As a result, there is a growing demand for natural and safe ingredients in the deodorant industry.<\/p>\n\n\n\n
CITROFOL\u00ae<\/sup>\u00a0AI<\/a>, also known as triethyl citrate, is a highly effective deodorising ingredient that is already widely used in formulating personal care products and can be used to formulate natural and aluminium-free deodorants. As 100% bio-based material, it is approved for use in natural personal care products certified according to the COSMOS and NATRUE standard. In deodorants,\u00a0<\/a>CITROFOL\u00ae<\/sup>\u00a0AI<\/a><\/strong>\u00a0functions as enzyme inhibitor, suppressing the enzymatic decomposition of sweat components and thus preventing body odour. When a deodorant containing\u00a0<\/a>CITROFOL\u00ae<\/sup>\u00a0AI<\/a><\/strong>\u00a0is applied to the skin, a deodorising cycle reaction is initiated. Triethyl citrate is enzymatically hydrolysed to citric acid and ethanol.\u00a0Citric acid<\/strong><\/a>\u00a0lowers the skin\u2019s pH, deactivating bacterial lipase enzymes and reducing the decomposition of sweat components that cause body odour. The skin\u2019s natural buffer function gradually neutralises the\u00a0citric acid<\/strong><\/a>, leading to an increase in skin pH and the reactivation of the bacterial enzymes. This starts the deodorising cycle with triethyl citrate again.<\/p>\n\n\n\n There are different mechanisms by which deodorising ingredients combat underarm odour. The basis to all of them is the fact that the unpleasant underarm odour is caused by bacterial degradation of sweat components. The reduction of malodour can either be achieved by (1) preventing or decreasing the amount of sweat formed in the armpit, by (2) binding or removing the volatile compounds in sweat that cause the odour, or by (3) preventing the bacterial breakdown of organic compounds. Deodorant formulations often combine different ingredients, such as (1) antiperspirants, (2) odour-covering agents, and odour absorbers, as well as (3) antimicrobial agents, and enzyme inhibitors, to effectively prevent malodour. In recent years, there has been increased concern among consumers about commonly used ingredients like alcohol, triclosan, and aluminium salts. Aluminium-free deodorants have gained popularity as some studies have argued the safety of aluminium salts and suggest a potential link between aluminium absorbed through the skin and breast cancer or Alzheimer\u2019s disease. However, there is currently no scientific evidence that exposure to aluminium from deodorants has a negative effect on health. Nevertheless, consumers are cautious, and many prefer to avoid deodorants containing aluminium.<\/p>\n\n\n\n Natural personal care<\/strong><\/a> ingredients with high functionality, like <\/strong><\/a>CITROFOL\u00ae<\/sup> AI<\/a><\/strong>, can help formulate deodorants that consumers desire for more natural and safe products.<\/p>\n\n\n\n For more information about <\/strong><\/a>CITROFOL\u00ae<\/sup> AI<\/a><\/strong> in deodorants, feel free to contact us.<\/p>\n\n\n\n Want to boost the efficacy of <\/strong><\/a>CITROFOL\u00ae<\/sup> AI<\/a><\/strong> in your deodorant?
