What are the alternatives? To obtain an oil phase product, natural waxes such as candelilla and carnauba waxes can be used as alternatives to mineral oil.21

Aluminum salts

What are they? Antiperspirants reduce sweat and decrease the pH of the skin, thus preventing bacteria from growing and causing foul odors. Aluminium salts, an important component in antiperspirants, minimize the sweating process by tightening pores and reducing the secretion of sweat.

Why the bad reputation? Exposure to aluminum via the repeated use of antiperspirant is regularly criticized and has been implicated in causing various diseases, including breast cancer.22 While to this day, a link to breast cancer has not been confirmed, the transcutaneous passage of aluminum, although low, is proven.23 After dermal application, the penetration of aluminum continues through hair follicles.

Should they be replaced? Probably. Aluminum salts can be irritating. They should not be applied to broken skin, and their use should be stopped immediately in case of itching.

What are the alternatives? Instead of aluminum salts, natural active ingredients such as triethyl citrate, alum stone and perlite can be used. Citric acid from the juices of cherry or currant inhibits the enzymes responsible for the decomposition of sweat. Alum stone (potassium alum) neutralizes odor and regulates perspiration without preventing the natural breathing of the skin. Perlite, a mineral extracted from volcanic rock, acts as a sponge to absorb moisture without preventing the natural breathing of the skin.24 Alchimie Forever does not use aluminum salts.
