Sweet Jojo Designs Silicone Bowl Liners with Lids for KitchenAid Mixer, Is It Non-Toxic?
Silicone bowl liners raise uncertainty. No coating details disclosed.
Sweet Jojo Designs reveals nothing about additive composition or manufacturing on these silicone bowl liners. Though silicone itself avoids PFAS, absent brand transparency leaves the risk profile unknown.

Is Sweet Jojo Designs KitchenAid Mixer non-toxic? What it is made of
These liners are silicone, a synthetic polymer backbone of silicon and oxygen that resists degradation and leaching far better than many plastics or coated metals. However, silicone compounds require additives (plasticizers, colorants, cross-linking agents) whose identity KitchenAid does not publicly disclose. The composition of these additives determines whether any chemicals migrate into food or air, especially when heated. Without transparency, you cannot independently verify safety margins.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Undisclosed plasticizers, colorants, and cross-linkers in silicone can leach into food, especially when heated above 300F or in contact with fatty/acidic foods. KitchenAid's silence on additive identity makes independent hazard assessment impossible.
Source, ATSDR ↗Heat-induced polymer breakdown and off-gassing
If silicone liners are used above their additive stability threshold (not published by KitchenAid), volatile organic compounds and odorous breakdown products may be released into mixed ingredients. Repeated heating cycles accelerate degradation.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Microplastic shedding from mechanical wear
No recalls or published reports of silicone liners fragmenting during mixer use. Silicone is more durable than plastic, but microtears from repeated flexing or sharp mixer accessories could theoretically release particles over years of heavy use.
Lead
No documentation of KitchenAid testing silicone liners for heavy metal pigments. Food-contact silicone should not contain these, but the brand has not publicly committed to color-safety standards.
Source, ATSDR ↗Coating or adhesive failure between silicone and bowl interface
Product details do not specify how the silicone liner adheres to the steel bowl. Delamination or peeling over time could expose adhesive residues to food; no field reports are documented, but failure mode is not ruled out.
How is this PFAS grade calculated?
The brand's record and disclosure
KitchenAid (owned by Whirlpool) maintains silence on PFAS use in silicone products and does not publish material safety data sheets or third-party certifications for bowl liners. The brand offers no documented history of independent testing for silicone additive safety. This absence of disclosure is a yellow flag in a category where competitors increasingly publish certifications (FDA food-contact status, NSF, or BPA-free claims).
How it compares in its category
Silicone bowl liners are a niche product; most mixer users rely on stainless steel, ceramic, or glass bowls without any coating. Among silicone mixing accessories, brands like Rubbermaid and OXO publish clearer heat limits and material certifications. KitchenAid's lack of publicly available safety documentation puts it at a disadvantage to competitors offering FDA compliance statements or third-party lab results.
If you buy it
Confirm the maximum safe temperature with KitchenAid before use; silicone typically withstands 400-500F but additives may have lower limits. Do not use at mixer speeds high enough to generate sustained friction heat beyond the rated temperature. Replace liners if discoloration, stickiness, or odor develops, as these indicate additive breakdown. Hand wash only (dishwashers exceed safe temperatures for some silicone products) and inspect the liner for microtears before each use.
