A cigarette paper is disclosed that contains at least one burn additive the concentration c(x) of which varies along a direction x of the cigarette paper. For the position-dependent concentration c(x) over an interval of length L, for x over the interval 0,L, ƒ(x)−Δc≤c(x)≤ƒ(x)+Δc. In this regard, 3
A cigarette paper is disclosed that contains at least one burn additive the concentration c(x) of which varies along a direction x of the cigarette paper. For the position-dependent concentration c(x) over an interval of length L, for x over the interval 0,L, ƒ(x)−Δc≤c(x)≤ƒ(x)+Δc. In this regard, 3 cm≤L≤11 cm, ƒ(x) is monotonic over the interval 0,L, but not a constant function over the entire interval, and Δc≤1% by weight, preferably ≤0.7% by weight and particularly preferably ≤0.5% by weight, and especially preferably ≤0.3% by weight and particularly preferably ≤0.15% by weight and Δc0% by weight, each with respect to the mass of the cigarette paper.

1. Cigarette paper comprising at least one burn additive that increases or reduces a smoldering speed of the cigarette paper, wherein: a concentration c(x) of the at least one burn additive varies along a direction x of the cigarette paper,a position-dependent concentration c(x) over an interval of length L for x over the interval [0,L] is: ƒ(x)−Δc≤c(x)≤ƒ(x)+Δc wherein: 3 cm≤L≤1 cm,f(x) is monotonic over the interval [0,L], but is not a constant function over the entire interval,Δc≤1% by weight and Δc≥0% by weight, respectively with respect to the mass of the cigarette paper,|ƒ(L)−ƒ(0)|≥2Δc,the air permeability of the cigarette paper comprising the at least one burn additive is between 20 cm min−1 kPa−1 and 200 cm min−1 kPa−1, andthe at least one burn additive comprises at least one of: tri-sodium citrate, tri-potassium citrate, further citrates, malates, tartrates, acetates, nitrates, succinates, fumarates, gluconates, glycolates, lactates, oxylates, salicylates, α-hydroxy caprylates, or mixtures thereof. 2. Cigarette paper according to claim 1, wherein Δc≤0.7% by weight. 3. Cigarette paper according to claim 1, wherein |ƒ(L)−ƒ(0)|≥0.5% by weight. 4. Cigarette paper according to claim 1, wherein the function f(x) is defined as: f(x)={c00≤x≤L1c0+(cL-c0)x-L1L2-L1L1
