Boudreaux's Butt Paste Maximum Strength Diaper Rash Cream, Ointment for Baby, 4 oz Tube

Boudreaux's Butt Paste Maximum Strength is a thick, cream-textured paste formulated with 40% zinc oxide, giving it more than twice the zinc oxide concentration of the Original Butt Paste Ointment. The formula contains no dyes, no preservatives, no parabens and no talc. The brand was created by a pharmacist and father of four, and has been made for over 40 years.

The paste has a dense, spreadable consistency that stays where it is placed rather than running or thinning out. It is made for daily use as part of a regular diapering routine, and the texture is intended to hold up through longer stretches, including overnight. A separate brush applicator is sold by the brand for those who prefer to apply it without using their hands.

• Size: 4 oz tube
• Format: ointment style paste
• FSA and HSA eligible in the US
• Other formats in the range: sensitive, natural aloe and butt barrier

When applying this paste, a thin, even layer over the affected area is typically enough given the high zinc oxide concentration. Because the formula is thick by design, warming a small amount between fingers for a moment can make it easier to spread. At diaper changes, wiping away any remaining paste too aggressively can cause irritation, so many caregivers gently pat or dab rather than rub during removal. The tube format makes it straightforward to dispense a controlled amount, which helps avoid waste compared to wide-mouth tub packaging.

Store the tube at room temperature and replace the cap firmly after each use to prevent the paste from drying out at the opening. When comparing maximum strength options in this category, the zinc oxide percentage is the most direct indicator of barrier thickness, so the 40% concentration here puts this paste at the higher end of over-the-counter options. The 4 oz tube is a practical mid-size for home use and fits in most diaper bags without taking up significant space. It suits parents who prefer a fragrance-free, no-dye formula and want something substantial enough for overnight protection without switching to a different product.
