Silicone additives for antiperspirants based upon alum
Recently there have been a number of new approaches to improving personal care formulations. Our recommended approach to formulation development is Minimally Disruptive Technology (MDT). Small additions of silicone compounds to formulation ( less than 5% by weight) can result in major alterations of aesthetics. This article will address additives that can be placed into formulations of this type to improve aesthetics.
ANTIPERSPIRANT / DEODORANT
One of the first topics that needs to be addressed is the concept of an alum based antiperspirant. The definition of terms that are used in the market of products used in the control of perspiration and the odor that it can cause is the first item that needs to be addressed. A very good discussion is provided reference (1).
The terms “antiperspirant” and “deodorant” are often used interchangeably but they do in fact refer to different products. Antiperspirants control sweat and body odor in two ways: firstly by preventing sweat reaching the skin surface and secondly by eliminating the bacteria that causes body odor via antimicrobial ingredients. Deodorants differ from antiperspirants as they only contain antimicrobial agents to prevent body odor; they do not control the flow of sweat. Both antiperspirants and deodorants often contain fragrances to help mask the smell of body odor.
When an antiperspirant is applied to the skin surface, its active ingredients – usually aluminum salts – dissolve in the sweat or moisture on the skin surface of the armpit. The dissolved substance forms a gel, which create ...
