What Is Dihydrogenated Tallow Phthalic Acid Amide?
Dihydrogenated Tallow Phthalic Acid Amide is a specialty ingredient derived from tallow, the fat obtained from cattle or sheep, that has been hydrogenated to improve stability. Chemically, it is an amide formed by reacting hydrogenated tallow fatty acids with phthalic anhydride, yielding a waxy solid that blends readily with oils and surfactants. Its cosmetic journey began in the mid-20th century when formulators looked for multi-purpose agents that could both clean the skin and stabilize oil-in-water mixtures. By converting readily available animal fat into a more refined amide, manufacturers gained a cost-effective component that performs reliably under a variety of pH levels and temperatures.
Production involves first hydrogenating raw tallow to saturate its fatty acid chains, which prevents rancidity. The saturated fatty acids are then reacted with phthalic anhydride in the presence of a catalyst to create the amide link. The finished material is purified, cooled, milled into flakes or beads then shipped to cosmetic labs worldwide.
You will most often find Dihydrogenated Tallow Phthalic Acid Amide in cream cleansers, bar soaps, shower gels, rich body lotions, makeup removers and certain hair conditioners. It is prized in both rinse-off and leave-on products for its dual role as a mild cleansing agent and a dependable emulsifier that keeps formulas smooth and uniform.
Dihydrogenated Tallow Phthalic Acid Amide’s Cosmetic Benefits/Uses
This ingredient brings more than one technical benefit to a formulation, making it a versatile addition for product developers.
- Cleansing: It helps dissolve and lift away excess oil, dirt and product buildup without stripping the skin of its natural moisture, supporting a gentle yet effective wash experience.
- Emulsifying: It binds water and oil components together, preventing separation so creams, lotions and washes stay stable, smooth and appealing throughout their shelf life.
Who Can Use Dihydrogenated Tallow Phthalic Acid Amide
Most skin types tolerate this ingredient well. Its mild cleansing action and ability to lock water and oil together make it especially helpful for normal, dry or mature skin that benefits from extra emollience. Oily or acne-prone users might find it a bit rich because it is derived from saturated fats, so lighter alternatives may suit them better.
Because it comes from animal tallow, it is not suitable for vegans or vegetarians seeking plant-based formulations. Those following religious or ethical restrictions related to animal by-products should also check if the source aligns with their standards.
No safety flags have been raised for pregnant or breastfeeding women when the ingredient is used topically in cosmetics. This is not medical advice and anyone who is expecting or nursing should run their skincare choices past a qualified healthcare provider to be safe.
Dihydrogenated Tallow Phthalic Acid Amide does not make skin more sensitive to sunlight, and it is fragrance-free so it rarely interferes with scented products already in a routine.
Potential Side Effects/Adverse Reactions
Individual responses to topical Dihydrogenated Tallow Phthalic Acid Amide vary. The following points list potential side effects, yet most people will not experience them when the ingredient is properly formulated and used as directed.
- Mild skin irritation in very sensitive individuals
- Contact allergy presenting as redness or itching
- Follicular clogging or breakouts in acne-prone skin
- Unwanted greasy feel in lightweight formulations
If any uncomfortable reaction occurs stop using the product and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 3 out of 5 (moderately comedogenic)
Dihydrogenated Tallow Phthalic Acid Amide is built from saturated animal fats, giving it an occlusive, wax-like texture that can sit on the skin surface and potentially trap dead cells inside pores. While its amide structure is more refined than raw tallow, enough residual fatty character remains to raise the likelihood of clogged follicles in people who already struggle with blackheads or whiteheads. Those prone to acne or frequent breakouts may want to choose lighter, plant-based emulsifiers instead.
Formulation level matters: when used at very low percentages in rinse-off cleansers it poses less risk, whereas higher levels in leave-on creams or makeup can increase pore-blocking potential.
Summary
Dihydrogenated Tallow Phthalic Acid Amide acts as a mild cleanser that lifts grime without stripping skin and as a sturdy emulsifier that locks water and oil together so lotions, washes and balms stay smooth. Its waxy backbone anchors surfactants in place, helping formulas remain creamy and homogenous through temperature swings.
The ingredient enjoys steady but niche popularity, appearing more in bar soaps and industrial-style cream cleansers than in trend-driven skincare releases. Consumers focused on vegan labels or oil-free claims often pass it by, yet formulators appreciate its reliability and low cost.
Overall safety data show minimal irritation or sensitization for most users. As with any new cosmetic it is wise to patch test a small area first, especially for acne-prone or highly sensitive skin.
