OverviewThe Deceth ingredients (Deceth-3, Deceth-4, Deceth-5, Deceth-6, Deceth-7, Deceth-8, Deceth-9, Deceth-10) are polyethylene glycol ethers of decyl alcohol. The number in the name indicates the average number of units of ethylene oxide in the molecule. Sims 4 mod teenage romance with adults. In cosmetic and personal care products, the Deceth ingredients are primarily used in the formulation of hair dyes and colors and other hair care products.
All of the Deceth ingredients function as surfactant -- emulsifying agents.
Designed for high-purity applications, Tygon® Sanitary Silicone Tubing's ultra-smooth, inner bore can reduce the risk of particle entrapment and microscopic buildup during sensitive fluid transfers. In-house analysis of the inner surface of Tygon® Sanitary Silicone Tubing compared to other silicone tubing shows that it is up to three times smoother.

The Deceth ingredients are produced by reacting ethylene oxide with decyl alcohol. The numerical designation refers to the average number of repeating ethylene oxide units in the molecule. Decyl alcohol is a fatty alcohol with 10 carbon atoms. The fatty alcohols in the other polyethylene glycol ether compounds reviewed by CIR include lauryl alcohol with 12 carbons, stearyl alcohol with 18 carbons, and cetearyl alcohol which is a mixture of cetyl alcohol (16 carbons) and stearyl alcohol.

SafetyThe safety of the Deceth ingredients has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel as part of the review of the alkyl PEG ethers group of ingredients. The CIR Expert Panel evaluated the scientific data and concluded that the alkyl PEG ethers, including the Deceth ingredients were safe as used in cosmetic products when formulated to be non-irritating.
CIR Review:
Based on similar structures, the CIR Expert Panel determined that the alkyl PEG ether compounds, including the Deceth ingredients could be reviewed together. Developmental and reproductive toxicity studies as well as mutagenicity data were all negative for these compounds. These compounds can irritate the skin. Therefore, the CIR Expert Panel concluded that the Deceth ingredients, as well as the other alkyl PEG ether ingredients were safe as used when formulated to be nonirritating. Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in the Deceth ingredients. The potential presence of this material is well known and can be controlled through purification steps to remove it from the ingredients before blending into cosmetic formulations.

8,9-Dihydrocannabidiol (H2CBD) is a synthetic cannabinoid that is closely related to cannabidiol (CBD) itself.[1] It was shown to have anti-seizure activity essentially identical to that of CBD in tests with rats. It may have certain advantages over CBD, in that it is fully synthetic, inexpensive to produce, and it is not a scheduled drug (cannabis extracts are controlled substances in most parts of the world). In addition, there is no path to synthesize the psychoactive substance tetrahydrocannabinol (THC) from H2CBD. CBD has been shown to convert to some extent to THC in the gastric tract,[2][3] and the deliberate laboratory conversion of CBD to THC is simple.[4][5] H2CBD has therefore been studied for its potential use as an alternative to CBD in terms of its lack of abuse liability and absence of psychotropic effects.[1]
