The most frequently used oils and fats are caprylic-capric glycerides, hydrogenated polydecenes, triethylhexanoin, shea butter and jojoba oil. They are thickened with synthetic or natural waxes, dextrin palmitate, etc.
Vegetal extracts such as thyme, sage, Eugenia caryophyllus and St. John’s wort are often used for their refreshing, soothing and mild antimicrobial actions. Either glycol or oil extracts can be used based on whether the formulation is oil-based or water/alcohol-based. Innovation The following are recent innovations in hygiene products, with more innovation to come.
Neat Feat has recently created a creama that fights against irritation in intimate zones, where the skin is subject to maximum chafing. The formula contains traditional emollients and claims to prevent skin rubbing discomfort and sweat-related skin disorders.
To provide deodorancy to the intimate area without traditional preservatives, a recent trial20 has combined the enzymatic deviator triethyl citrate with the nontraditional preservative sodium caproyl/lauroyl lactyl lactate. In vitro tests demonstrate the combination’s antibacterial efficacy, particularly against the Candida species that cause skin disorders in intimate zones, while in vivo tests show a 24-hour lasting deodorant efficacy. Triethylcitrateb is an enzymatic deviator, as it is hydrolyzed by bacterial enzymes, leading to the formation of citric acid that inhibits the further action of sweat decomposing enzymes.
